The 300 mm insulated steel sleeve bearing is designed for demanding electrical applications, featuring a robust steel construction with an insulated outer layer to prevent electrical current passage and protect against bearing fluting. With an approximate outer diameter of 308.3 mm and available lengths from 80 mm to 120 mm, this sleeve bearing offers reliable performance in high-load environments. The insulation provides effective electrical isolation, supporting voltage ratings suitable for industrial motor protection. Key features include precise dimensional tolerances, durable steel backing, and compatibility with standard bearing housings, making it ideal for use in motors and rotating equipment where electrical insulation and mechanical strength are critical.
