Established in 2016, UDM continuously invests in research and development, applying for or registering two to three patents each year. While most competitors manufacture ball bearings, UDM focuses on fluid bearings, which overcome the shortcomings of ball bearings using fluid between metals to minimize friction. UDM manufactures fluid bearings with carbon composite materials, which have 1,100%-better abrasion ratio than other products. Their excellent durability effectively reduces equipment maintenance costs.

Differentiation of hybrid composite bearing
• Improved properties in all fields to compare with white metal 18% ~900%
• High efficiency (Reduce power loss-Torque)
• High reliability under emergency situation (Oil cut, Lower amplitude, higher load, higher oil supply
temp., etc)
Technical value
• Reduce operating cost by high efficiency & reliability
• Reduce back up system cost (No need jacking oil system)
• Apply unique design by overcoming of mechanical limitation ( more than 2itmes higher load, higher
wear resistance, lower power loss, lower amplitude, etc.)
• If oil supplying temp. is higher due to you can’t sufficient oil cooling when your system has to be
operated Middle east area, Africa, etc.), The hybrid composite bearing can give higher reliability &
reducing power loss
• Strong marketing factor by product differentiation

25. Understanding the Industry
- Anxiety about being supplied
with proper price and quality
- Anxiety due to non-standardized
intermediate process
- Source diversification policy
- Various problems that existing
suppliers have not improved
- Find new suppliers by developing
new products
- Reduce costs by trading with
more specialized companies
- - Supplier becomes buyer
- Introduction through network
- Internet search
- Onsite visits
-> Lack of information about
suppliers
-> Limited to proximity
-> Detailed information for pre-
conformity assessment (no
equipment, experience, major
products)
-> Supplier evaluation not
possible before site visit
-> Lack of expertise by replacing
generations of buyers
- Request a quote based on
limited information
-> Low Estimated Reliability
-> Anxiety about quality and
delivery
-> Non-realistic estimate
criteria by non-specialized
suppliers
- Verifying pre-performance
- Verification of test processing
request
-> Additional orders upon verification
-> High failure rate (delivery, poor
quality, etc.)
-> Restart process
-> Much time and money
Manufacturing, Semi-machining, Engineering and Knowledge
