K20008AR0 ultra thin wall angular contact ball bearing is metric open type A thin‑section bearing with 8 mm cross‑section. It provides high‑precision rotary support for large‑diameter components under combined radial‑axial loads. Widely applied in heavy‑duty compact turntables and special industrial equipment.
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.
