Brake assembly with asymmetrical shoulder bearing

A brake assembly comprising:

• a rotatable part configured to be rotatable by an actuator;
• a translatable part operably coupled with the rotatable part, the translatable part configured to be axially translatable relative to the rotatable part to move a brake pad according to rotation of the rotatable part;
• and
• a bearing assembly comprising:
• an inner race provided on an outside of the rotatable part, the inner race having a first inner shoulder, a second inner shoulder, and an inner curved surface between the first inner shoulder and the second inner shoulder;
• an outer race having a first outer shoulder, a second outer shoulder, and an outer curved surface between the first outer shoulder and the second outer shoulder;
• and
• rollable bodies rollably disposed between the inner race and the outer race,
• wherein the first inner shoulder of the inner race and/or the first outer shoulder of the outer race are asymmetric to the second inner shoulder of the inner race and/or the second outer shoulder of the outer race, respectively,
• wherein:
• the first inner shoulder and the second inner shoulder of the inner race are protruded at a same height as each other, and
• the second outer shoulder of the outer race positioned to be farther from the brake pad than the first outer shoulder of the outer race is more inwardly protruded than the first outer shoulder of the outer race positioned to be closer to the brake pad than the second outer shoulder of the outer shoulder.
