K09020XP0 ultra thin wall four point contact ball bearing is 20 mm cross‑section metric open‑type X thin‑section bearing. It provides reliable multi‑direction heavy‑load capacity for radial,axial and moment conditions while keeping lightweight advantages. Mainly used for robot rotary joints,optical turntables and space‑constrained heavy‑load mechanical assemblies.

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.
