K12008AR0 ultra thin wall angular contact ball bearing is open type A metric thin‑section bearing with 8 mm cross‑section. It handles radial plus single‑direction axial loads,features slim profile and high running accuracy. Ideal for large‑bore compact rotary mechanisms in automation and optical inspection systems.
A-type angular contact ball bearings - 8mm series feature a 15° contact angle design in a miniature form factor, precision-engineered for applications requiring compact dimensions combined with high-speed capability and axial load support. Available in open and sealed configurations, with a fixed bore diameter of 8mm and a cross-section height of 8mm. These bearings deliver smooth high-speed rotation, low heat generation, excellent axial rigidity, and consistent precision, making them ideal for dental handpieces, small high-speed motors, miniature spindles, model aircraft, medical instruments, and precision optical devices where space is limited and high rotational accuracy is essential.
