KC180XP0 ultra thin wall four point contact ball bearing is maximum‑giant‑size KC‑XP0 series thin‑section four‑point contact ball bearing. Retains KC‑series uniform square thin cross‑section for ultra‑large bore dimension. Capable of bearing multi‑direction combined loads. Mainly deployed for extra‑large compact rotary tables,large robot assemblies and oversized special‑layout precision rotary mechanical systems.

X-type four-point contact ball bearings - KC series feature a high-speed optimized four-point contact raceway design with lightweight cages and precision-balanced internal geometry, delivering reliable axial and radial load support at elevated rotational speeds while maintaining bidirectional load capability. Available in standard and thin-section high-speed configurations, with bore diameters ranging from 20mm to 250mm. These bearings deliver low friction heat generation, high-speed stability, compact design, and excellent positional accuracy, making them ideal for high-speed slewing rings, precision rotary tables, indexing devices, packaging machinery, and high-speed automation equipment.
