The 270 mm insulated cast iron sleeve bearing features an approximate outer diameter of 278.3 mm (10.956 inches) with a tight tolerance of ±0.05 mm (0.002 inches). It is available in multiple sleeve lengths including 70 mm, 80 mm, 90 mm, 100 mm, and 110 mm, allowing for versatile application. The cast iron construction provides durability and strength, while the insulation prevents electrical current passage through the bearing, reducing fluting and pitting. This sleeve bearing is designed for precision fits with a minimum clearance of 0.15 mm (0.006 inches) up to 6 inches diameter, ensuring reliable performance in heavy-duty industrial environments.
