S06003AS0 ultra thin wall stainless steel angular contact ball bearing is metric constant cross‑section thin‑wall bearing manufactured from SUS440C stainless steel for corrosion resistance. Type A angular contact structure carries combined radial and one‑direction axial loads, maintains consistent 3mm cross‑section, features low torque and high rotational accuracy. Suitable for robotic joints, optical equipment, medical instruments and humid corrosive working environments.

A-type angular contact ball bearings - 2.5mm series (stainless steel) feature an ultra-miniature 15° contact angle design with martensitic stainless steel rings and balls, engineered for applications requiring extreme space savings combined with corrosion resistance and high-speed capability. Available in open configurations only, with a fixed bore diameter of 2.5mm and a cross-section height of 2.5mm. These bearings deliver ultra-compact dimensions, excellent corrosion resistance, high-speed rotational capability, low torque operation, and reliable performance, making them ideal for micro-motors, miniature medical devices, dental handpieces, micro-robotics, precision optical instruments, implantable devices, and micro-sensor systems where both miniaturization and corrosion resistance are critical.
