Thrust Bearing Series 3000


This bearing is located at the end of the 4701-3000 direct drive crank assembly and power lift systems. It rides on the thrust nut and takes the pre load off the crank system.


Installation tip: Take note of the direction of the thrust bearing installed in the crank system. The thrust bearing needs to face in the proper direction for the system to operate correctly. If the bearing is installed backwards, the system will be difficult to crank. The proper installation has the open / smaller surface of the bearing facing against the base of the thrust nut. This allows it to spin freely when the system is compressed.

Measurements are 1-7/8" wide, 5/8" tall, 1" center.
