KB090XP0 ultra thin wall four point contact ball bearing combines extra‑large bore and KB‑series ultra‑thin equal cross‑section. It delivers high‑precision rotation under multi‑direction combined‑load environment. Widely applied for large‑diameter compact positioning turntables,special industrial rotary platforms and large automation precision assemblies.
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.
