Product Description

Description:

1. Description
Thrust ball bearing is a sperate bearing, the contact ball is 90° , this kind of bearing is composed of inner ring, outer ring and retainer. Single-row thrust ball bearing can carry axial load from single direction. Two-row thrust ball bearing can carry axial load from double direction. Thrust ball bearing with spherical rings has aligning performance, which can eliminate installation error.

Thrust ball bearings are produced as single direction or double direction thrust ball bearings. They are designed to accommodate axial loads only and must not be subjected to any radial load.
Thrust ball bearings are separable, i.e. the shaft washer, housing washer(s), ball and cage assembly(s) can be mounted separately. Shaft washers have a ground bore to enable an interference fit. The bore of the housing washer is turned and always larger than the shaft washer bore.


2. Structure
Single-row thrust ball bearing
Double-row thrust ball bearing
CHIK Single Direction Thrust Ball Bearings consist of two flat washers with raceways, balls and cage which are detachable. The washers have a flat seating surface therefore they have to be embedded so that all balls are equally loaded. Bearings only transfer axial loads in one direction.

3. Cage
Steel stamping cage, machine solide cage(brass) Thrust ball bearings have as standard pressed steel cage, where the material and application is not marked. Larger size bearings use massive brass cage to offer more robust solutions.

4. Features
CHIK thrust ball bearings are design to accommodate large axial load, however they must not be subjected to radial load. Most frequent bearings are single direction thrust ball bearings. During operation these bearings must be constantly subjected to a specific axial load. These bearings can be also combined with spherical rings to cope with small initial misalignments.

5. Application
Machine spindle, worktable of vertical lathe, auto steering mechanism, Fluid control valves
Machine tool tables and spindles
Oil and gas rotary tables
Screw Jacks
