KF400XP0 ultra thin wall four point contact ball bearing is the maximum‑bore member of KF‑XP0 Reali‑Slim thin‑section bearing series. It maintains constant 0.750‑inch square cross‑section at ultra‑giant bore, withstands heavy radial, bidirectional axial and overturning moment loads. Ideal for super‑large compact rotary tables,heavy‑duty large rotary assemblies and ultra‑giant‑bore precision automation equipment.

KF series X-type four point contact thin section ball bearing features equal cross section design. It can bear radial load, bidirectional axial load and overturning moment load in compact installation space. Available in chrome steel or stainless steel, multiple precision grades. Widely applied in robotic joints, rotary tables, medical equipment and aerospace machinery, offering stable precision operation.
