Overview of self-aligning ball bearings
A self-aligning ball bearing is a bearing equipped with spherical balls between the inner ring of two raceways and the outer ring whose raceways are spherical.
Self-aligning ball bearings have two structures: cylindrical bore and tapered bore, and the cage is made of steel plate, synthetic resin, etc. Its characteristic is that the outer ring raceway is spherical and self-aligning, which can compensate for the errors caused by the misalignment and shaft deflection caused by the self-aligning ball bearing, but the relative inclination of the inner and outer rings shall not exceed 3 degrees.
Product characteristics of self-aligning ball bearings
Mainly bear radial load, and can bear small axial load at the same time. The axial displacement of the shaft (housing) is limited within the clearance limit, and it has a self-aligning performance. It allows normal operation under the condition that the inner and outer sides are not relatively inclined. It is suitable for parts where the support seat hole cannot strictly guarantee the coaxial.
Features and advantages of self-aligning ball bearings
1. It can adapt to static and dynamic misalignment. Like spherical roller bearings or CARB bearings, this type of bearing also has the ability to self-align.
2. Excellent high-speed performance. Compared with any other types of rolling bearings, self-aligning ball bearings produce the lowest friction, and the temperature rise is lower even at high speeds.
3. Minimal maintenance requirements. Because the bearing produces less heat, the temperature is lower, thus prolonging the service life of the bearing and the maintenance interval.
4. Low friction. The clearance fit between the rolling elements and the outer ring can reduce friction and frictional heat.
5. Excellent light load performance. Self-aligning ball bearings have lower minimum load requirements.
6. Low noise. For example, self-aligning ball bearings can reduce the noise and vibration level of the fan.
