KD180XP0 ultra thin wall four point contact ball bearing is maximum‑giant‑size KD‑XP0 series thin‑section four‑point contact ball bearing. Retains KD‑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 - KD series feature a corrosion-resistant four-point contact raceway design with stainless steel rings and balls, engineered to support bidirectional axial loads and moderate radial loads in harsh environments while maintaining reliable moment rigidity. Available in open, shielded, and sealed configurations, with bore diameters ranging from 15mm to 200mm. These bearings deliver excellent corrosion resistance, reliable performance in moist or chemically exposed conditions, and long maintenance-free service life, making them ideal for medical equipment, food processing machinery, marine systems, chemical processing equipment, and outdoor automation applications.
