The 400 mm insulated cast iron sleeve bearing (compatible with bearings 6052, 6244, 6338) features an approximate outer diameter of 410.3 mm (16.154 inches) with a tight tolerance of ±0.05 mm (0.002 inches). Made from durable cast iron, this insulated sleeve prevents electrical current passage through the bearing, reducing fluting and pitting damage. It is designed for press-fit installation and provides reliable electrical insulation between the bearing shell and housing. This sleeve is ideal for heavy-duty applications requiring robust mechanical support and electrical isolation in motors and generators. Dimensions and material specifications ensure long-term stability and performance.
