KB020XP0 ultra thin wall four point contact ball bearing belongs to KB‑XP0 Reali‑Slim thin‑section bearing family with 0.375‑inch equal square cross‑section. Made of premium 52100 chrome bearing steel and fitted with brass snap‑over cage. This Type‑X four‑point contact bearing can simultaneously undertake radial loads, bidirectional axial loads and overturning moment loads. It delivers low‑friction smooth rotation with compact lightweight profile, one single bearing can replace two angular contact bearings to save installation space. Widely used for rotary tables,optical instruments,robot joints and compact precision automation equipment under strict space‑limited conditions.

X-type four-point contact ball bearings - KB series feature a heavy-duty four-point contact raceway design with robust cage construction and premium bearing steel, engineered to support extremely high axial loads while maintaining bidirectional load capability and excellent moment rigidity. Available in single-row and double-row configurations, with bore diameters ranging from 50mm to 600mm. These bearings deliver exceptional axial load capacity, superior shock resistance, enhanced durability under heavy loads, and long maintenance-free service life, making them ideal for large slewing rings, crane turntables, wind turbine pitch/yaw systems, stacker reclaimers, and heavy-duty material handling equipment.
