KD300XP0 ultra thin wall four point contact ball bearing is the largest‑size KD‑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 - 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.
