Products Description

A unidirectional thrust ball bearing is composed of a washer shaped ring with a ball rolling raceway and a cage assembled with a ball. The ring installed on the shaft is called the shaft ring, the ring installed on the bearing housing is called the seat ring, and the bi-directional bearing installs the middle ring on the shaft for use.

Unidirectional thrust ball bearings can withstand axial loads in one direction, while bidirectional bearings can withstand axial loads in two directions.

In order to reduce the impact of installation errors, a thrust ball bearing with a spherical seat ring is also installed on the outer ring.

Small bearings mainly use steel plate stamped cages. Large bearings, using cut retainers.

This type of bearings can be used to carry radial-axial combined loads.At the same time in carrying radial loads.additional axial threst will be implicated.Therefore it is in duplex arrangement in general.The outer ring and inner ring with rollers assemble can be separately.Besides both the axial and radial clearaces are adjustable in mounting.

The larbe tapered angular bearings is mainly used to carrysingle directional axial loads.thus it is not suitable to carry radial loads alone.

Double rows or four rows tapered roller bearings is used to carry heavy radial loads and part of the axial loads in either direction.There are separating rings between the interval of inner rings and that of the outer rings.By changing the width of the separaing rings.the aim of clearance adjustment can be achieved.
