SKF 51212 Thrust Ball Bearing

SKF 51212 is a single-direction thrust ball bearing designed to support axial loads in one direction while allowing smooth shaft rotation, with a bore diameter of 60 mm, an outside diameter of 95 mm, and a width of 26 mm. Its separable design, steel cage, and standard precision make installation, disassembly, and maintenance straightforward in gearboxes, pumps, vertical shafts, screw jacks, cranes, and other machinery where axial shaft positioning and high rotational speeds are required, though it must not be subjected to radial loads. It weighs approximately 0.63–0.69 kg and supports grease or oil lubrication, enabling reliable operation in industrial power transmission systems. Common replacements include NSK 51212, FAG 51212, and Timken 51212.
