KG040XP0 ultra thin wall four point contact ball bearing belongs to KG‑XP0 Reali‑Slim thin‑section bearing family with 1.000‑inch equal square cross‑section. Made of premium 52100 chrome bearing steel and fitted with brass snap‑over cage. This Type‑X four‑point contact bearing can simultaneously undertake radial loads, bidirectional axial loads and overturning moment loads. It delivers low‑friction smooth rotation with compact lightweight profile, one single bearing can replace two angular contact bearings to save installation space. Widely used for rotary tables,optical instruments,robot joints and compact precision automation equipment under strict space‑limited conditions.SKF 集...

X-type four-point contact ball bearings - KG series feature an ultra-heavy-duty four-point contact raceway design with reinforced cage construction and oversized rolling elements, engineered to support extreme axial loads and heavy radial loads while maintaining bidirectional load capability and exceptional moment rigidity under the most demanding conditions. Available in heavy-duty single-row and double-row configurations, with bore diameters ranging from 80mm to 800mm. These bearings deliver maximum axial load capacity, superior shock load resistance, extended service life in extreme conditions, and exceptional structural rigidity, making them ideal for large wind turbine main shaft systems, giant excavator slewing rings, offshore crane turntables, heavy steel mill equipment, and ultra-large-scale material handling systems.
