Double Row Angular Contact Ball Bearing

Double row angular contact ball bearings can withstand large radial loads, mainly radial loads, combined radial and moment loads.
Double row angular contact ball bearings have limited tilt between the inner and outer rings, and the permissible tilt angle depends on the bearing's internal clearance, bearing size, internal design and the forces and moments acting on the bearing, while the maximum permissible tilt angle should ensure that no excessive additional stress is generated in the bearing.

Product Introduction

product-625-215

If there is an inclination angle between the inner and outer rings of the bearing, it will affect the life of the bearing, and at the same time cause the bearing running accuracy to decrease and the running noise to increase.
Double row angular contact ball bearings generally use nylon cages or brass solid cages. Care should be taken when mounting double row angular contact ball bearings that although the bearings can accommodate axial loads in both directions, care should be taken not to allow the main axial load to pass through the groove on the notched side if there is a ball notch on one side. When the bearings are used, care should be taken to accommodate the main load on the raceway side without ball notching.

Application for Single Row Angular Contact Ball Bearings:

Compared to single row bearings, double row angular contact ball bearings have better rigidity and it can withstand overturning moments. The bearings are non-separable. It is particularly suitable for applications with high rigidity requirements. It is often used in the front wheel hub of a car.
