Work Requirements for Self-aligning Ball Bearings

What is self-aligning ball bearing
Self-aligning ball bearing is a bearing fitted with spherical ball balls between the inner ring of two raceways and the outer ring of a spherical raceway. The curvature center of the outer ring raceway surface is consistent with the bearing center, so it has the same self-aligning function as the automatic self-aligning ball bearing. In the case of shaft and housing deflection, it can be automatically adjusted without increasing the bearing burden.

Characteristics of self-aligning ball bearings
1. The outer ring raceway is spherical, with automatic self-aligning, which can compensate for the errors made by the self-aligning ball bearing with different concentricity and shaft deflection, but the relative inclination of the inner and outer rings shall not exceed 3 degrees.
2. Can bear large radial load, but also can bear a certain axial load. The outer ring raceway of this kind of bearing is spherical, so it has the performance of self-aligning. When the shaft is bent or tilted and the relative tilt of the center line of the inner ring and the center line of the outer ring is less than 1° ~ 2.5°, the bearing can still work.
3. There are two kinds of inner hole of self-aligning ball bearing: cylindrical and conical. The taper of the conical inner hole is 1:1 2 or 1:30.

Working requirements of self-aligning ball bearing
1. For heavy loads, poor working conditions or bearing configuration with special requirements for sealing, built-in contact sealed aligning roller bearings can be used. The outer dimension of the bearing is exactly the same as that of the non-sealed bearing, and it can replace the non-sealed bearing in many occasions. The allowable self-aligning Angle is 0.5°, and the working temperature is -20℃~110℃. The bearing has been filled with an appropriate amount of lithium-based anti-rust grease, and grease can be added according to user requirements.
2. According to the difference between the inner ring and the cage used, it can be divided into two basic types: Type C and Type CA. Type C bearing is characterized by no inner ring and stamping cage with steel plate, while Type CA bearing is characterized by both sides of inner ring and using solid cage made of car. This kind of bearing is especially suitable for heavy load or vibration load work.
3. The self-aligning roller bearing is equipped with a drum roller bearing between the inner ring with two raceways and the outer ring with a spherical raceway. The curvature center of the outer ring raceway surface is consistent with the bearing center, so it has the same self-aligning function as the automatic self-aligning ball bearing. The inner diameter of the bearing ring is taper hole, which can be installed directly or installed on the cylindrical shaft by using a tight set sleeve or a disassembly cylinder.
