K02508XP0 ultra thin wall four point contact ball bearing is open‑type X metric thin‑section ball bearing with 8 mm cross‑section. Gothic‑arch raceway enables it to take radial, bidirectional axial and moment loads simultaneously. Single bearing can replace two angular contact bearings,features lightweight,compact envelope and high rotational accuracy. Widely used in robot joints,gimbals,optical inspection devices and compact automation machinery with limited installation space.

X-type four-point contact ball bearings - 8mm series feature a miniature four-point contact raceway design with a single inner ring and split outer ring configuration, engineered to support bidirectional axial loads and moderate radial loads in an ultra-compact package. Available in open configurations only, with a fixed bore diameter of 8mm and a cross-section height of 8mm. These bearings deliver compact design, high axial rigidity, space-saving installation, and reliable bidirectional load capacity, making them ideal for miniature slewing rings, small robot joints, precision optical mounts, micro-positioning stages, miniature rotary tables, and compact automation equipment where both axial load capacity and space efficiency are critical.
