Products Description

This type of bearings can only be used to carry axial loads but not radial loads and to fix axial direction but not radial direction.Therefore,it is used to work together with the radial ball or roller bearings.Besids,it is merely suitable for low speed rotation and can not be applied in the high speed machinery rotation.In order to prevent sliding at the ball-to -raceway contact caused by centrifugal force.It is necessary to apply for the axial preloading mounting.

Double direction thrust ball bearings can be used to carry axial loads in both directions,else can limit the axial dis-placement in both directions too.The thrust ball bearings with seating rings that used to compensate for fitting errors.it not suit able for self-alignment during operation.
