1: Thrust ball bearings features:1, one-way thrust ball bearings can only support axial load in one direction from the axis of its ring structure, with a full set of ball seat and maintain the frame. Which axis ring installed in the shaft seat ring bore hole bigger than the shaft, seat hole can not be grinding.2, two-way thrust ball bearings can withstand import axial load in both directions on both sides it has a ring with the axial channel and the two seat,

Needle roller and cage thrust assemblies are complements of small diameter needle rollers arranged in a spoke-like configuration. Needle rollers are equally spaced by means of a cage whose web section separates the rollers and provides guidance to keep them tracking in an orbital path. The purpose of these assemblies is to transmit a thrust load between two relatively rotating objects while greatly reducing friction.

Install thrust bearing, they should test shaft ring and shaft centerline perpendicularity. Method is to dial gauge fixed on the tank shell face, so touch the table top of the head ring in the bearing raceway upper rotating shaft bearings, side observation dial gauge pointer, if the pointer yaw show ring and shaft axis is not perpendicular to the centerline.
