    TriSteel | Stainless Steel Bearing Reinforced for Longer Wear

TriSteel™ are the only bearings to offer a stainless steel substrate and are among the top performing composite bearings. Featuring a unique polymer liner that is sintered to a porous bronze interlayer, TriSteel bearings are self-lubricating and can withstand the most rigorous of working environments.  TriSteel can easily manage high-loads and excessive speeds, and can protect your machinery in the rare instance of a liner wear-thru, since the supporting interlayer is also self-lubricating. 

Whether your job calls for standard or metric dimensions, or requires a steel, zinc or copper-plated backing, TriSteel has you covered.  We’ll help you match the right material to enhance product wear life by evaluating the speed, load, temperature and lubrication of your hardware.  And we’ll do it all at a competitive value.

TriSteel Benefits

Self-lubrication (both inner and outer layers)

TriSteel bearings utilize special polymer liners for self-lubrication and improved wear properties.

Longer wear

The metal backing supports liner materials made to withstand high loads, speeds and adverse environments.

Standard or metric dimension

TriSteel bearings are available in inch and metric dimensions in various combinations of liners and backing materials.

TriSteel Technical Resources

TriSteel in Automotive

Choose the TriSteel bearing that’s best for your application:

TriSteel AC Data Sheet

  • Ultraflon 601 (AC) POM lined metal backed bearing system
