QA1 AIB10T AIB-T Series Spherical Bearing PTFE Lined 5/8 in. Bore

The QA1 AIB10T is an AIB-T Series spherical bearing engineered for demanding suspension and performance applications. Built from heat-treated chromoly alloy steel, this bearing delivers superior wear characteristics over traditional carbon steel alternatives, making it the go-to choice for race cars, street rods, and performance builds.

The bearing ball is precision-ground from 52100 bearing steel, heat treated, and hard chrome plated for smooth, consistent rolling under load. The race features a self-lubricating PTFE liner, eliminating the need for routine greasing while reducing friction and extending service life. The race itself is constructed from heat-treated alloy steel with a protective coating for corrosion resistance.
