K02520XP0 ultra thin wall four point contact ball bearing is open‑type X metric thin‑section ball bearing with 20 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 higher load capacity,compact envelope and high rotational accuracy. Widely used in robot joints,gimbals,optical inspection devices and heavy‑duty automation machinery with limited installation space.

X-type four-point contact ball bearings - 20mm series feature a four-point contact raceway design with balanced dimensions, engineered to support bidirectional axial loads and moderate radial loads in a compact form factor with reliable moment rigidity. Available in open configurations only, with a fixed bore diameter of 20mm and a cross-section height of 20mm. These bearings deliver compact design, high axial rigidity, bidirectional load capacity, smooth rotational accuracy, and dependable long-term performance, making them ideal for precision slewing rings, industrial robot joints, machine tool rotary tables, packaging machinery, medical equipment, and automation systems where space efficiency and reliable bidirectional axial load support are essential.
