Self-aligning ball bearing

A self-aligning ball bearing is a bearing equipped with spherical 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 center of the bearing, so it has the same centering function as automatic self-aligning ball bearings. When the shaft or casing is bent, it can be automatically adjusted without increasing the bearing burden. Self aligning roller bearings can withstand radial loads and axial loads in two directions. The radial load capacity is large, suitable for situations with heavy loads and impact loads. The inner diameter of the inner ring is a tapered hole bearing that can be installed directly. Alternatively, use a locking sleeve or disassembly cylinder to install it on the cylindrical shaft. The cage uses steel plate stamped cage, polyamide formed cage, and copper alloy car made cage

There are two types of structures for self-aligning ball bearings: cylindrical hole and conical hole. The material of the retainer includes steel plate, synthetic resin, etc. Its characteristic is that the outer ring raceway is spherical and has automatic centering, which can compensate for the errors caused by different centricity and shaft deflection in the centering ball bearing. However, the relative inclination of the inner and outer rings should not exceed 3 degrees

Can withstand large radial loads and also withstand certain axial loads. The outer ring raceway of this type of bearing is spherical, so it has centering performance. When the shaft is bent or tilted under force, the relative inclination between the inner ring centerline and the outer ring centerline does not exceed 1 degree 2.5° At this time, the bearings can still work

There are two types of inner holes in self-aligning ball bearings: cylindrical and conical. The taper of the conical inner hole is 1:1 2 or 1:30. In order to enhance the lubrication performance of the bearing, a circular oil groove and three oil holes are machined on the outer ring of the bearing
