KB030XP0 ultra thin wall four point contact ball bearing features uniform KB‑series square thin cross‑section to save housing installation space and reduce component weight. It withstands radial, bidirectional axial and overturning moment loads and runs stably. Suitable for optical rotary modules,precision rotary platforms and robot joint compact 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.
