KC120XP0 ultra thin wall four point contact ball bearing is maximum‑size KC‑XP0 series equal‑cross‑section four‑point contact ball bearing. It keeps slim KC‑series cross‑section even for maximum bore dimension,undertakes multi‑direction combined loads. Mainly adopted in oversized compact rotary tables,large special‑purpose optical equipment and super‑large‑bore precision automation rotary components.

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.
