Insulated cast iron bearing sleeves provide reliable electrical isolation for motors and rotating equipment, preventing current-induced bearing damage. These sleeves are designed for bearing sizes 6010, 6208, and 6307, with a standard length of 80 mm and an approximate outer diameter of 84.3 mm (3.319 inches). Constructed from high-quality cast iron, they offer excellent durability and thermal stability in demanding environments. The insulation feature effectively blocks stray currents, reducing the risk of fluting and pitting. Ideal for industrial applications, these sleeves ensure long bearing life, easy installation, and compatibility with standard housings.
