The 140 mm steel shaft sleeve bearing is compatible with bearing models 6028, 6228, and 6328, featuring a sleeve length of 100 mm. The 6028 bearing typically has a bore diameter of 140 mm, an outer diameter of 210 mm, and a width of 33 mm, made from chrome steel SAE52100 for high durability and low friction, suitable for high RPM applications. The 6228 bearing measures 140 mm bore, 250 mm outer diameter, and 42 mm width, with a dynamic load rating around 13000 kgf, designed for heavy-duty use. The 6328 bearing offers a larger outer diameter of 300 mm and width of 62 mm, with a basic dynamic load rating up to 253000 N, supporting radial loads efficiently. These bearings provide high rigidity, silent operation, and can handle combined radial and axial forces, making them ideal for industrial machinery and heavy equipment.
