Application scenarios of angular contact ball bearings

There is a contact angle between the ring and the ball, with standard contact angles of 15 °, 30 °, and 40 °. The larger the contact angle, the greater the axial load capacity, and the smaller the contact angle, the more favorable it is for high-speed rotation. Single row bearings can withstand radial and unidirectional axial loads, while DB combination, DF combination, and double row bearings can withstand radial and bidirectional axial loads. DT combination is suitable for situations with large unidirectional axial loads and insufficient rated load of a single bearing. ACH type bearings with small ball diameters and many balls are mostly used for machine tool spindles. Angular contact ball bearings are suitable for high-speed and high-precision rotation

Structurally, two single row angular contact ball bearings with a back combination share the inner and outer rings, which can withstand radial and bidirectional axial loads. There are also sealed types of bearings without filling grooves, mainly suitable for steel plate stamped cages (bowl shaped... single row; S-shaped, crown shaped... double row), copper alloy or phenolic resin cut cages, and synthetic resin formed cages

Main use:

Single column: machine tool spindle, high-frequency motor, gas turbine, centrifugal separator, small car front wheel, differential small gear shaft

Dual row: oil pump, Roots blower, air compressor, various transmissions, fuel injection pump, printing machinery

Four point contact ball bearings can withstand radial and bi-directional axial loads. A single bearing can replace front or back combination angular contact ball bearings,
