Material Notes:

Ultraflon 601T (AT) POM bronze with PTFE, lined metal back bearing system, high PV, self lube, high speed. This liner will run with zero lubrication required. Most commonly used in clip bearings, lift and tilt on medium speed and load applications. Liner thickness allows for secondary machining to accommodate misalignment or minor ID tolerance corrections.
