This slideshare presentation offers a definition of what push-pull control cables are and how they are used. Furthermore, it offers a breakdown of some design considerations for push-pull cables, information about cable end fittings, and provides a long list of products offered by CMA Cable.

1. Push-Pull Control
Cables
By: Cable Manufacturing & Assembly

2. When Are Solid Core Controls Used?
• Used in applications that require the transmission of forces in both
the push and pull mode of operation.
• Most products use various conduit styles and solid wire cores in
their construction.

3. How Are Push-Pull Cables Used?
• If the load is light and the combination of cable and conduit is
carefully considered, stiffer, small diameter cables can be used for
push-pull cables.
• To eliminate the need to apply separate fittings or terminations, sold
wire cores can be formed on the cable ends.
• Use large bend radii and simple routing to avoid creating a
permanent set in the core wire.
• All push-pull controls have a larger capacity in the pull mode than in
the push mode.

4. More InformationAbout Push-Pull Cables
• The molded conduit fittings, conduit selection, assembly function,
and dimensions of push-pull cables help to affect the design of these
products.
• It is important to be aware of these factors and to have a practical
design for these products in order to create the most successful,
reliable, and cost-effective custom cable assembly.

5. Push-Pull Cables Design Considerations
• A solid wire or specially constructed core materials MUST be used
for pushing applications except for extremely light loads.
• 1x7 or 1x19 cables can be used for the lightest of loads
• Minimal bends and turns along with a large radii is required for the
cable assembly routing in the final application
• Save the highest work loads for the pull direction
• The loads should be half of the pull load when in compression
mode
• 5 inches or less should be used for the travel dimension

6. Push-Pull Cables Design Considerations
• The number of bends in the system as well as the difference
between cable outside diameter and conduit inside diameter will
affect the amount of cable travel
• This is known as lost motion in the cable assembly
• To simplify your mating construction design, consider using plastic
molded and steel swaged conduit end fittings.
• Custom molded conduit and end fittings may also be used.
• Keep the push-pull cable as straight as possible when exiting the
conduit to the final attachment point.

7. Control Cable/Cable End Fittings
• It is easy to create a custom cable control assembly with CMA’s large
inventory of core wire, conduit fittings, clamps, and accessories.
• By applying these components to cable specifications and technical
information and guidelines provides by the design guide, you can
exercise creativity and flexibility while solving various functional
problems.

9. Control Cable/Conduits/ConduitFittings
• Do you need flexible routing with good compressive strength? How
about a more rigid application with good crush resistance?
Regardless of what you need, you’ll find the perfect conduit for your
project through CMA Cable.
• Some of our available conduits include:
• Braided Reinforced
• Bowden
• Flat Wire Bowder with a Liner or Long Lay
• If you’re looking to create a durable, flexible, and cheap cable
manufacturing assembly, consider combine our shuttle-molded
components with our standard control components.
