The self-aligning ball bearing is a bearing with spherical balls and a centering function between the inner ring of the two raceways and the outer ring of the spherical race. The radial load capacity is large, and it is suitable for heavy load and impact load. The self-aligning ball bearing cage is made of steel plate or synthetic resin. The characteristic is that the outer ring raceway has a spherical shape and has self-aligning property, but the relative inclination of the inner and outer rings must not exceed 3 degrees. The inner diameter of the self-aligning ball bearing is cylindrical or conical. The conical inner bore has a taper of 1:1 2 or 1:30. In order to enhance the lubrication performance of the bearing, an annular oil groove and three oil holes are machined on the outer ring of the bearing. Self-aligning ball bearings with dust caps and seals are filled with the right amount of grease. They should not be heated or cleaned before installation. No lubrication is required during use. Adapt to operating temperature - 40 °C to + 120 °C. between.
