Self-Aligning Ball Bearing

A spherical ball bearing is assembled between the inner ring of a self-aligning ball bearing 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 centering function as the automatic centering ball bearing. In case of deflection of shaft and shell, it can be adjusted automatically without increasing bearing burden. Self aligning roller bearing can bear radial load and axial load in two directions. Large radial load capacity, suitable for heavy load and impact load. The inner diameter of the inner ring is a bearing with a tapered hole, which can be directly installed. Or install it on the cylindrical shaft with a tightening sleeve and a disassembly cylinder. The cage uses steel plate stamping cage, polyamide shaped cage and copper alloy car cage. The self-aligning ball bearing has two structures of cylindrical hole and conical hole. The cage is made of steel plate and synthetic resin. Its characteristic is that the outer ring raceway is spherical and has automatic centering, which can compensate the error caused by the centering ball bearing with different centrality and shaft deflection, but the relative inclination of the inner and outer rings shall not exceed 3 degrees. [1] It can bear large radial load and certain axial load. The raceway of the outer ring of this type of bearing is spherical, so it has centering performance. When the shaft is bent or inclined by force, the relative inclination between the center line of the inner ring and the center line of the outer ring is not more than 1 ° - 2.5 °, the bearing can still work. The inner hole of self-aligning ball bearing has two types: 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, an annular oil groove and three oil holes are machined on the outer ring of the bearing.
