Angular contact ball bearings mostly use brass cages, but also steel stamping cages, nylon plastic cages or bearings without cages, and those with spacers
Allowable tilt angle
The tiltability between the inner and outer rings of angular contact ball bearings is limited. The allowable tilt angle depends on the internal clearance of the running bearing, bearing size, internal design, and the force and moment acting on the bearing. The maximum allowable tilt angle should ensure Will not produce excessively high additional stress. If there is an inclination angle between the inner and outer rings of the bearing, it will affect the life of the bearing. At the same time, the bearing's running accuracy will decrease and the running noise will increase.
The clearance of single row angular contact ball bearings. Each bearing manufacturer has its own supporting radial clearance standard to ensure the contact angle. There is no unified standard in the country. The radial clearance of double row angular contact ball bearings is still a self-made matching clearance, and the axial clearance company has a self-made recommended value.
Mainly used for machine tool spindles, high frequency motors, gas turbines, centrifugal separators, front wheels of small cars, differential pinion shafts; oil pumps, Roots blowers, various compressors, various transmissions, fuel injection pumps, printing machinery Wait.
