Angular contact ball bearing can bear radial load and axial load at the same time, and can work at a higher speed. The larger the contact angle, the higher the axial load carrying capacity. Single-row angular contact ball bearings can only withstand single direction axial load, so generally are long to use pairs of installation.
angular contact ball bearings are non-separate design, the shoulders on both sides of the inner and outer rings are different in height. In order to increase the load capacity of the bearing, the shoulder on one side is machined lower, so that the bearing can be filled with more balls. Single row angular contact ball bearing back-to-back pair form, can withstand two directions of the axial load, while can withstand radial load.
can withstand larger radial load mainly radial and axial combined load and moment load, limiting the axial displacement of both sides of the shaft.
1. single row: machine tool spindles, high frequency motors, gas turbines, centrifugal separators, small car front wheels, differential pinion shafts.
2. Double row: oil pumps, Roots blowers, air compressors, all kinds of transmissions, fuel injection pumps, printing machinery.
Deep groove ball bearings can bear radial load and two-way axial load. Frictional resistance is small and the speed is high. Suitable for high speed rotation and low noise and low vibration requirements.
Sealed type bearing with steel plate dust cover or rubber seal is pre-filled with appropriate amount of grease, outer ring with stop ring or flange bearing, that is easy to axial positioning, and easy to install in the shell.
Maximum load type bearings have the same size as standard bearings, but the inner and outer rings have a filling groove, increasing the number of loaded balls and increasing the rated load Mainly applicable cage, steel plate stamping cage (waveform, crown-shaped … single row; S-shaped … double row) copper alloy or phenolic resin cut cage, synthetic resin forming cage.
automotive: rear wheels, transmissions, electrical device components; electrical: general-purpose motors, household appliances; other: instruments, internal combustion engines, construction machinery, railroad vehicles, loading and unloading machinery, agricultural machinery, various industrial machinery.
