PolyLube self-lubricating bearings offer low coefficient of friction and high load-carrying capacity. PTFE super-filaments, which exhibit tensile strengths 20 times greater than PTFE resins, are integrated into the bearing surface. They resist cold flow and demonstrate impressive wear characteristics. This engineered composite material permits optimum strength and rigidity, and is strong enough to support heavy loads and pliant enough to tolerate moderate shaft misalignments without highly stressing the bearing corners, says the company.

The high-strength composite wall acts like a spring – the thicker the wall section of the bearing, the more opportunity there is to design for deflection as needed. The supporting surface supports the shaft primarily as a function of the load, rather than the shaft clearance.

PolyLube bearings will support a bearing load of 30,000 psi while handling high radial and longitudinal stresses. They also resist shock loading and abrasion. These qualities make them suitable for operation of high loads in rotational and stroking movements as well as in oscillation. The bearings allow designers to eliminate grease, increase functionality, and achiever more cost-effective bearing solutions, says the company.
