Timken K8112 Bearing Locknut

The Timken K8112 bearing locknut is a steel, threaded-shaft mounting nut that securely positions and preloads bearings on shafts to prevent axial movement in heavy-duty industrial equipment. With an outside diameter of 3.180 in (80.77 mm) and a width of 1.250 in (31.75 mm), it weighs 1.29 lb (0.59 kg) and is designed for reliable bearing mounting in bearing-mounted industrial rotating machinery. Used in industrial gearboxes, conveyors, mining and aggregate equipment, construction machinery, agricultural equipment, and power transmission systems, it helps maintain proper preload and long service life. This K-series locknut is manufactured by Timken (MPN K8112), and common replacements include Timken K8112M or OEM bearing lock nuts with equivalent dimensions.
