Four Point Angular Contact Ball Bearings

Four point angular contact ball bearings comprise 1 piece solid outer rings, 2 pieces split inner rings and ball and cage assemblies with brass or phenolic resin cages. The raceway profiles are such that the ball contacts the outer ring at two points and the split inner ring at one point each. Such a design allows the bearing to carry axial loads in both the directions like a double row angular contact ball bearings without taking up as much axial space. The balls have a contact angle of 35° with each ring.

Types of four point angular contact ball bearings:

QJ 2 series;

QJ 3 series;

QJ 10 series;

Bearing Features:

Less axial space: take up less axial space than double row bearings.

High load carrying capacity: a large number of balls are incorporated;

Separable design of inner rings: easier mounting and dismounting of the bearing.

Applications:

Agricultural machinery;

Pumps;

Industrial machinery for cleaning and bottling;

Machining equipment for steel, glass, marble, wood, etc;
