The 150 mm insulated cast iron sleeve bearing is designed for use with bearing numbers 6020, 6217, and 6314, featuring an approximate outer diameter of 156.3 mm (6.154 inches) and a length of 40 mm. This sleeve provides electrical insulation to prevent current passage through the bearing, reducing the risk of fluting and pitting. Constructed from durable cast iron, it offers reliable performance in demanding motor and industrial applications. The sleeve's precise dimensions and insulation properties make it ideal for protecting bearings from electrical damage while maintaining structural integrity and operational efficiency.
