KC300XP0 ultra thin wall four point contact ball bearing is the largest‑size KC‑XP0 Reali‑Slim thin‑section bearing. It holds fixed 0.500‑inch square cross‑section at maximum giant bore, supports heavy radial, bidirectional axial and overturning moment loads. Perfect for ultra‑large compact rotary tables,heavy‑duty light‑weight rotary assemblies and super‑large‑bore precision automation equipment.

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.
