S16003CS0 ultra thin wall stainless steel deep groove ball bearing is metric constant cross‑section thin‑wall bearing made of SUS440C stainless steel for anti‑corrosion performance. Type C radial contact structure accepts radial loads and moderate bidirectional axial loads, keeps stable 3mm cross‑section, delivers low torque and high rotational precision. Suitable for medical instruments, optical devices, semiconductor equipment and humid corrosive working conditions.

C-type deep groove ball bearings - 2.5mm series (stainless steel) feature an ultra-miniature deep-groove raceway design with martensitic stainless steel rings and balls, engineered for applications requiring extreme space savings combined with corrosion resistance and reliable radial load support. 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, smooth rotation, low noise levels, and dependable long-term performance, making them ideal for micro-motors, miniature medical devices, dental handpieces, micro-robotics, precision optical instruments, implantable devices, micro-sensor systems, and miniature actuators where both miniaturization and corrosion resistance are essential.
