K02513AR0 ultra thin wall angular contact ball bearing is open‑type A metric thin‑section ball bearing with 13 mm cross‑section. It bears combined radial and unidirectional axial loads, delivers high stiffness, low friction and outstanding rotational accuracy. Widely applied in robot joints,optical instruments,medical devices and automation machinery with limited installation space.

A-type angular contact ball bearings - 13mm series feature a 15° contact angle design in a compact form factor, precision-engineered for applications requiring moderate load capacity combined with high-speed capability and reliable axial load support. Available in open and sealed configurations, with a fixed bore diameter of 13mm and a cross-section height of 13mm. These bearings deliver smooth high-speed rotation, low vibration levels, consistent axial rigidity, and extended service life, making them ideal for high-speed miniature motors, small machine tool spindles, robotics joints, medical equipment, optical instruments, and precision automation devices where compact design and rotational accuracy are critical.
