Motor bearings, also known as electric motor bearings or motor bearings, are specialized support components used in electric motors. The code GB/T 272-93 covers its structure, dimensions, types, and accuracy characteristics. These bearings reduce friction through metal balls or rollers, supporting the rotation of the motor spindle. The main types include rolling bearings, sliding bearings, joint bearings, and oil-impregnated bearings, with rolling bearings being widely used due to their strong load-bearing capacity
