The 300 mm insulated steel sleeve bearing features an outer diameter of approximately 308.3 mm (12.137 inches) with a tight tolerance of ±0.05 mm (0.002 inches) and is available in lengths ranging from 80 mm to 120 mm. This bearing is designed with an insulated steel construction to protect against electrical currents, enhancing durability and reducing bearing failure risks. It is suitable for high-load applications requiring electrical insulation. The sleeve’s robust steel backing ensures strength, while insulation properties provide protection in motor and industrial environments where eddy currents are a concern.
