- 6. Debunking the myths • Today’s engineers have more component specifying choices than ever. • Standard or application-specific components? Both have advantages and disadvantages. • This decision should be driven by the application.
- 7. Debunking the myths • Design engineers should choose the ideal component for their design instead of what is in a catalog or online. • We’ll explore the strengths and applications for both standard and special components. • We’ll help engineers make the most educated decision when specifying.
- 8. Special vs. Standard Components
- 9. What is a standard component? • Manufactured to an exact industry standard. • Predictable in design. • Governed by specific guidelines for tolerances and dimensions. • Generally produced in mass quantities. • No customization for specific applications.
- 10. When is a standard component used? • In applications that don’t require components to be modified or have unique considerations. • When space is unrestricted. • When engineers have the time and funds to design around the component or purchase additional materials to accommodate it. ROUGHLY 90% OF component usage roughly
- 11. Why choose standard components? • Standard components have usually been the most common and accessible. • They are often seen as the only viable option. • Easily found in catalogs. • Seem more cost- and time-effective. However: not necessarily true any longer.
- 12. What is a special component? • A special component is precisely designed and built to fit a specific application. • Special components have no limit or standards for size, shape or construction.
- 13. When is a special component used? • When standard components don’t fit the space, won’t last within the application, etc. • When engineers need to define a specific use. • For new designs without predetermined limits. ROUGHLY 10% OF component usage roughly
- 14. Why choose special components? • When engineers need more flexibility than a standard piece offers. • To accommodate the exact needs of a specific application. • When a standard component isn’t working. • To solve a problem that a standard component can’t.
- 15. The Disadvantages of Standard Components
- 16. The disadvantages of standard components • Today’s designs require that components used are precise and fit the exact application needed. • Engineers design around a standard component instead of getting the exact component they need. • To make a standard component work often requires additional materials, time and cost to mount the piece properly.
- 17. The disadvantages of standard components • Mass produced and uniform components often limit engineers’ options. • There are times when standard components work just fine.

- 19. The truth about special components • Special components are often avoided because there are many misconceptions surrounding them. • They have been viewed as too expensive, hard to get and impossible to replicate. • Some manufacturers have been working to overcome these obstacles and give engineers the option to get the exact component they need.
- 20. 3 Myths About Special Components
- 21. Myth #1: higher cost Myth #1: Custom components are more expensive (even cost-prohibitive) than standard ones Standard components often require extra parts, increasing costs by 10-15%. Special components can be designed to withstand repetitive use and extra force, decreasing the frequency of needed replacement. Additional engineering time to make standard components work can increase a project timeline and cost. Designs with special components will work better and more effectively over time, reducing life cycle costs.
- 22. Myth #2: longer production time Myth #2: Custom components take much longer to produce Designing around standard components already adds considerable time to the project. Special components will eliminate the time spent searching for, securing and applying parts to make a standard component “fit.” Equipment changes allow for smaller production runs, reducing the required manufacturing time. Careful ordering can make the production process just as fast as ordering standard components off the shelf.
- 23. Myth #3: parts are hard to get Myth #3: Spare or replacement parts for custom components aren’t readily available. Spare or replacement parts can often be produced in less time than it took to build the original part. This gives engineers the flexibility to order what they need, when they need it. Streamlined processes and equipment allow for a ready supply of additional parts for each specialized component designed and built. Some manufacturers don’t even have a minimum for custom orders.
- 24. What’s the real story? • Special components have become: • more affordable. • more convenient. • quicker to secure. • Manufacturers are overcoming roadblocks to help design engineers get the exact component they need for their application.
- 25. Making the Standard vs. Special Component Decision
- 26. Consider your options - 1 1. What is the temperature environment the component will be operating in? 2. Will the component be subject to any kind of “wash down”? 3. Will there be any kind of abrasive materials in the area? 4. How much linear force do you require out of the component? 5. Do you have enough room for a “standard” component? 6. Are you replacing an existing component that is failing? YES NO YES NO YES NO YES NO
- 27. Consider your options - 2 7. Do you require the flexibility of adjusting the end of stroke position? 8. Does your application require you to know where the piston is at times? 9. What is the operating pressure? 10. What is the operating media? YES NO YES NO
- 28. Summary
- 29. Summary • Design engineers should choose special or standard components based on what’s best for their design. • Standard components are often mass-produced and may require design compromises. • Special components can be cost effective and easily obtained and serviced with modern production techniques.

Editor's Notes
- Today’s engineers have more choices than ever when it comes to specifying the proper components for all types of applications. There are advantages and disadvantages to choosing an application-specific component or a standard component. This decision is mostly driven by the application.
- The goal of a design engineer should be to choose the ideal component for a design, and not to limit this decision by what is in a catalog or what is found online. Therefore, today we will explore the strengths and appropriate applications for both standard and special components so that design engineers can make the most educated decision when specifying for their designs.
- What is a standard component? A component manufactured to an exact industry standard. They are predictable in design. Trade organizations such as NFPA, ISO and others have established specific guidelines governing the tolerances and dimensions of standard components. Standard components are generally produced en mass – more of a production driven model – with no customization for specific applications.
- When is a standard component used? Standard components are usable in a wide range of applications that don’t require components to be modified or have unique considerations. They are normally chosen when space is unrestricted. Standard components cannot be manipulated or customized without additional cost, so engineers will design around this type of component or purchase additional materials to accommodate the piece. Standard components are currently used roughly 90% of the time.
- Why do engineers choose standard components? Standard components are historically the natural selection for design engineers because they have been the most common and accessible. Standard components are often seen as the only option, as they appear in catalogs and have been the more cost effective and timely option in the past. However, recent innovations have now made it possible to use special components when it would have been impossible or cost and time prohibitive before.
- What is a special component? A special component is precisely designed and built to fit a specific application. There is no limit or standard to the size, shape or construction of a special component.
- When is a special component used? Special components lend themselves to designs in which standard components do not fit the space, do not last within the application, etc. Special components also allow engineers to define how to use them and are great for new designs where the engineer’s only limit is his or her creativity. They are currently used roughly 10% of the time.
- Why choose special components? Design engineers use special components when they need more flexibility than what a standard piece offers. Design engineers can create a component to accommodate the exact needs of a specific application. Additionally, you may choose to specify a special component when you’ve tried the standard and it’s simply not working properly – to solve a problem that a standard component cannot.
- There are several disadvantages of standard components. First, the complexity and accuracy involved in today’s designs requires that components used are precise and fit the exact application needed. Because all applications are different, design engineers often end up designing around a specific component instead of securing the exact component that they need. To make a standard component work within an application, engineers are often required to source additional materials to mount the piece properly, which increases the project time and cost.
- Continuing with the disadvantages of standard components – Components that are mass produced and designed to a certain, uniform standard are not always what will work best within a design or application, but engineers often feel limited by these options. There are times when standard components work just fine. But when they won’t, it’s important to note that there are other, affordable and timely options at your disposal. But first, you have to understand the truth about these special components.
- The truth about special components is that Special components are often avoided because there are many misconceptions surrounding them. Historically, these application-specific components have been viewed as too expensive, hard to get and impossible to replicate. In recent years, some manufacturers have devoted energy to overcoming these obstacles and addressing the issues today’s engineers face to ensure they have the option to get the exact component they need.
- To illustrate the changes that have taken place, I’ll walk you through three myths and facts:
- Myth #1: Custom components are more expensive (even cost-prohibitive) than standard ones This is false! Facts: That isn’t universally true anymore. Standard components often require extra parts to properly mount within a design, which can increase the costs by as much as 10-15% on a single project. Multiply that across a number of components required for a single design, and that cost increase is significant. This also requires additional engineering time and can slow down a project’s timeline as modifications are needed. Both of these scenarios increase the overall cost of the project. Application-specific components may be more expensive on the front-end, but the savings realized over the life of the piece and overall application are significant. With a component designed SPECIFICALLY for the application, the design will work much better and more effectively over time. Special components can also be designed to withstand repetitive use and extra force, allowing them to be built correctly the first time and decreasing the frequency of needed replacement.
- Myth #2: Custom components take much longer to produce This is also false! Facts: Engineers often find themselves designing around standard components, which – on its own – can add considerable time to the project. Many manufacturers are now using manual equipment, allowing them to produce smaller quantities of components, keeping them from breaking into larger production runs. This decreases the turnaround time of a special component to roughly the same amount of time it takes to secure a standard component. With the right information on the front end, this process can be just as quick as ordering a standard off the shelf. Choosing an application-specific component also eliminates the additional time and work spent searching for, securing and applying additional parts needed to make a standard component fit.
- Myth #3: Spare or replacement parts for custom components aren’t readily available. Again, this is false! Facts: Manufacturers can often produce spare or replacement parts for a custom component in less time than it took to build the original part. Today’s manufacturers have streamlined processes and utilize manual equipment that enables them to have a readily-available supply of additional parts for each specialized component they design and build. Some manufacturers do not even require a minimum order for custom orders, giving engineers the flexibility of ordering what they need, when they need it.
- What’s the real story? Over the years, these special components have become more affordable, more convenient and quicker to secure. With a growing number of complex and precision applications, manufacturers are overcoming previous roadblocks ensuring that design engineers get the exact component they need for their application.
- So how do you know which decision to make when considering standard and special components? For the purpose of this example, we will pretend we’re in the process of specifying a pneumatic cylinder for your next machine.
- When you’re designing your next machine, consider your options by asking yourself the following questions: What is the environment that the component will be operating in? Hi temperature? Low temperature? Will the component be subject to any kind of “wash down”? Will there be any kind of abrasive materials in the area, such as metal shavings, grinding dust, etc…? How much linear force do you require out of the component? Do you have enough room for a “standard” component? If not, an inline multi-piston component might meet the application requirements Are you replacing an existing component that is failing? If so, it’s possible to design a component to last longer in the same footprint, while addressing the failure point
- Here are the last 4 questions to consider when considering special vs. standard components for your next design: Do you require the flexibility of adjusting the end of stroke position? Does your application require you to know where the piston is at times? What is the operating pressure? What is the operating media? Air, hydraulic, water, brake fluid, etc… Answering these simple questions will allow you to determine whether your design (and its application) will be better served by a standard or an application-specific component.
- In summary, we have reviewed the pros and cons of standard and special components, and debunked some common myths about special components. The key points to remember are: Design engineers should choose special or standard components based on what’s best for their design, rather than compromising the end product. Standard components are often mass-produced and may require design trade-offs. With modern production techniques, special components can be cost effective – especially when total lifecycle cost is considered. Special components can also be produced with minimal turnaround times, and spare and replacement parts can be easily available.
