KC250XP0 ultra thin wall four point contact ball bearing features extra giant bore while keeping KC‑series 0.500‑inch equal square cross‑section. Chrome bearing steel construction improves overall rigidity to cope with complex multi‑direction combined loads. Widely applied in extra‑large positioning rotary tables,large‑scale automation rotary units and oversized precision optical machinery.

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.
