KC140XP0 ultra thin wall four point contact ball bearing is over‑large‑bore KC‑XP0 Reali‑Slim thin‑section bearing. It preserves KC‑series 0.500‑inch square equal cross‑section with huge bore size. High‑grade bearing steel provides reliable rigidity against multi‑direction combined loads. Widely used for extra‑large compact rotary tables,light‑load robot rotary assemblies and large‑diameter precision positioning 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.
