The Best Places to Buy Angular Contact Ball Bearing Online and In-Store

The structure of angular contact ball bearings produces an axial component when a radial or combined load is applied; therefore, two opposed bearings or a multi-bearing arrangement are used.
A preload is often used to increase the rigidity of single-row angular contact ball bearings, particularly in the main spindles of machine tools where high running accuracy is crucial.
Bearings with a contact angle of 30° (A) or 40° (B) typically use pressed steel, molded resin, or machined brass cages, though machined synthetic resin or specialized polyamide resin cages are used for certain applications.

SeriesPressed Steel CagesMachined Brass Cages79A5,C--A--C--A,B--C--A,B--

Features

• Support both radial and axial loads
  Single-row ACBBs can take radial loads and axial loads in one direction with typical contact angles of 30° or 40°.
• A variety of contact angles
  Larger contact angles offer greater capacity for axial loads, while smaller contact angles are better for high-speed rotation.
• Two opposed bearings are used to adjust internal clearance. Pressed steel cages are common, though polyamide resin cages are typically used for high-precision bearings with contact angles under 30°.

Applications

• High rigidity
  Ideal for applications requiring bearing rigidity.
• Pumps, compressors, screw chillers, elevator hoists

A back-to-back paired mounting of single-row angular contact ball bearings is turned into a bearing with a single inner ring and outer ring.
Double-row angular contact ball bearings are often used as fixed-end bearings as they can sustain axial loads in both directions and have the capacity to take moment loads.
These bearings feature pressed steel cages.

Features

• Compact design
  An integrated back-to-back mounting of two single-row ACBBs in the form factor of a single inner ring and outer ring.
• Support axial loads
  Double-row ACBBs can take axial (thrust) loads in both directions.

Applications

• Compressors, press machines, automatic guided vehicles (AGVs), belt conveyors

Four-point-contact ball bearings feature an inner ring split into two pieces. Just one of these bearings can sustain significant axial loads in both directions.
A contact angle of 35° allows for high axial load capacity. This type is suited for carrying pure axial loads or combined loads where the axial load is high.
These bearings feature machined brass cages.

Features

• Easy to handle
  The outer ring of these specialized single-row angular contact ball bearings can be separated from the two halves of the inner ring split along a plane perpendicular to the shaft center.
• High axial load capacity
  With a contact angle of 35°, four-point-contact bearings are well-suited for pure or combined loads where axial load is high.
• Compact
  A single bearing can be used to replace a face-to-face or back-to-back arrangement of bearings.

Applications

• Tractor transmissions, robot gearboxes, servomotors
