Product Description

High Quality Top Grade Super Precision Gcr15 Material Heavy Duty KHRD Qj238n2ma Four Point Contact Ball Bearing for Bullet Train                         
 

Four Point Contact Ball Bearing 
     
Four point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported (Load ratio). The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves.

Features and Benefits

 -Accommodates axial loads in both directions
 -Less axial space
 These bearings take up considerably less axial space than double row bearings.
 -High load carrying capacity
 A large number of balls are incorporated, giving the bearing its high load carrying capacity.
 -Separable design
 The split inner ring leads to easier mounting and dismounting of the bearing. 
 -Improved oil flow
Limited inner ring deformation when subjected to high clamping forces

Applications

Angular contact bearings are commonly used in gearboxes, pumps, electric motors, and clutches and other high-speed applications. Bearings having larger contact angles can support larger axial loads, and the contact angle does not usually exceed about 40 degrees.
