A new series of custom engineered high speed bearings, made from a proprietary thermoplastic (patent pending) which lasts up to 10 times longer than conventional PEEK, PEI, and polyimide bearings, is being introduced by Tri-Mack Plastics Manufacturing Corp.

Maxton HS-Series High Speed Bearings are made from a composition of proprietary reinforcing and lubricating fillers that can be formulated with PEEK, PEI, polyimide, and other resins, to achieve specific performance characteristics. The bearings feature 100,000 PV @ 1,000 FPM, which is the highest PV limit at high speed of any injection-moldable material, claims the firm.

Providing up to 10 times the life of conventional thermoplastic bearings, the high speed bearings are self-lubricating and operate at up to 500°F. They can be machined with ±.0005" tolerances in complex shapes from 1/8" x ¼" up to 24" dia. Applications include electric and pneumatic motors, rotary vane pumps, and fans.
