Hot sale durable original self-aligning ball bearing 1209 1210 1211 1212 long life

The self-aligning ball bearing has two structures: cylindrical hole and conical hole, and the material of the cage includes steel plate, synthetic resin, etc. Its characteristic is that the outer ring raceway is spherical in shape and has automatic centering, which can compensate for errors caused by different centricity and shaft deflection. The reasons for its centering are as follows:The curvature center of the outer race surface of the self-aligning ball bearing is consistent with the bearing center, so it has the same self-aligning function as automatic self-aligning ball bearings. When the shaft and casing are bent, they can be automatically adjusted without increasing the bearing burden; Self aligning ball bearings can withstand large radial loads as well as certain axial loads. The outer ring raceway of this type of bearing is spherical in shape, so it has centering performance. When the shaft is bent or tilted under force, causing the relative inclination between the inner ring centerline and the outer ring centerline to not exceed 1 degree to 2 or 5 degrees, the bearing can still work.
