The 230 mm insulated cast iron sleeve for bearing 6226 offers reliable electrical insulation and mechanical support in demanding industrial environments. With an approximate outer diameter of 238 mm (9.371″) and available in various lengths, this oversized sleeve features a robust cast iron construction designed to prevent electrical current from passing through the bearing, reducing the risk of fluting and pitting damage. The insulation layer ensures effective dielectric performance, making it suitable for applications where electrical isolation is critical. Engineered for durability and precise fit, it provides excellent dimensional stability and long service life in heavy-duty rotating equipment.
