KF400CP0 ultra thin wall deep groove ball bearing is the largest‑size member of KF‑CP0 Reali‑Slim thin‑section bearing series. It maintains constant 0.75‑inch square cross‑section for super‑giant bore, handles heavy radial‑dominated combined loads. Suitable for extra‑large rotary tables,large rotary assemblies and super‑giant‑bore compact precision rotary equipment.

C-type deep groove ball bearings - KF series feature a low-noise optimized deep-groove raceway design with precision-honed raceways and high-quality lubricants for ultra-quiet operation, while maintaining reliable radial and moderate axial load capacity. Available in open, shielded, and low-noise sealed configurations, with bore diameters ranging from 5mm to 100mm. These bearings deliver extremely low noise levels, minimal vibration, and smooth rotational performance, making them ideal for household appliances, HVAC systems, office equipment, electric fans, and noise-sensitive automation devices.
