Does the 73 12ACM bearing have a direction on the rear axle of the motor?

73 12ACM bearing is an angular contact ball bearing. Angular contact ball bearings can bear radial and axial loads, as well as pure axial loads, and can work at high speed. Single row angular contact ball bearings can only bear axial load in one direction. When bearing radial load, it will cause additional axial force, which can only limit the axial displacement of the shaft or shell in one direction. If installed in pairs, the outer rings of a pair of bearings have the same opposite end faces, with the wide end face facing the wide end face and the narrow end face facing the narrow end face, so that additional axial force can be avoided and the axial clearance of the shaft or the housing can be limited in two directions. Angular contact ball bearing has more balls than deep groove ball bearing, so it has the largest bearing capacity, strong rigidity and stable operation. The radial clearance can be adjusted by mutual displacement of the inner ring and the outer ring.
