K12013AR0 ultra thin wall angular contact ball bearing is open‑type A metric thin‑section bearing with 13 mm cross‑section. It accommodates radial plus one‑way axial loads,features slim profile and superior rotational precision. Perfect for large‑bore compact rotary mechanisms in automation and optical inspection systems.
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.
