Double-row angular contact ball bearings

Innner Diameter: 100-340mm
Outer Diamater: 180-520mm
Weight: 6.1-132kg

Features
Technical data

The design of double row angular contact ball bearing is almost totally same as that of the single row angular contact ball bearing. However, its axial dimension is relatively small.So,the double row angular contact ball bearings can be considered to a pair of back-to-back single row bearings. It can bear axial loads in two directions as well as torques.

Double row angular contact ball bearings usually have fitting solt, the side of the raceway without fitting solt must carry main loads when bearings are in use.
