Angular Contact Ball Bearings


Angular Contact Ball Bearings

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

Self Aligning Ball Bearings are very useful in applications where there is a displacement of the centers around the shaft and housing rotate and deflection are likely to occur. Self-aligning bearings come in a pressed steel cage, snap-type steel cage and copper alloy machined cages.

Types Of Angular Contact Ball Bearings

  • Thrust Bearing.
  • Cylindrical Roller Bearings.
  • Ball Bearings.
  • Deep Groove Ball Bearings.
  • Rolling Bearings.
  • Axial Load.
  • Bistables

Features And Benefits Of Angular Contact Ball Bearings

  • Support both radial and axial loads These bearings 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, with the internal clearance adjusted. Pressed steel cages are generally used, though polyamide resin cages are typically used for high-precision bearings with contact angles under 30°.
  • Self-aligning ball bearings are a great way to reduce the noise and vibration levels for instance, in fans.

Application And Uses Of Angular Contact Ball Bearings

  • Self-aligning ball bearings produce less friction than other kinds of rolling bearings, which allows them to run cooler even at speeds that are high.
  • This type of bearing is most commonly used in the machinery industry, industrial fans, agriculture, etc.
  • High rigidity Ideal for applications requiring bearing rigidity.
  • Pumps, compressors, screw chillers, elevator hoists
