 AP-2 Integrated Bearing Assemblies
 |Based on the design of the AP™  bearing, Timken’s AP-2™ rail bearing is designed for heavier loads. It  reduces bearing set outs fuel cost and bearing failure due to water ingress.  It also reduces  component wear rejection  and axle fillet damage, decreasing potential axle failure and ultimately  reducing the occurrence of axle grooving.
