Anti - Friction Heavy Industry Angular Contact Thrust Bearing High Speed
Angular Contact Ball Bearings 7309B
Types
1. Single row angular contact ball bearings: 78XX,79XX,70XX,72XX,73XX,74XX
It can only support axial load in single direction.
2. Double-row Angular contact ball bearings: 52XX,53XX,32XX,33XX,LD57,LD58
This is basically a back-to-back mounting of two single-row angular contact ball bearings, but their inner and outer rings are each integrated into one.
3. Matched Angular Contact Ball Bearings
Back-to-back (DB) (Example)7208 A DB
Face-to-face(DF) (Example)7208 B DF
Tandem(DT) (Example)7208 A DT
4. Four-point angular contact ball bearings: QJ2XX,QJ3XX
The inner ring is split radially into two pieces.
Their design allows one bearing to sustain significant axial loads in either direction.
The contact angle is 35°, so the axial load capacity is high.
This type is suitable for carrying pure axial loads or combined loads where the axial loads are high.

Description
Angular contact ball bearings, also known as spindle ball bearings, consist of an inner ring, outer ring, ball, and a cage to contain and separate the ball. They are designed for combination radial and axial loading. Single-row bearings have high thrust capacity in one direction. Double-row Conrad bearings can accommodate thrust in both directions.
