The 270 mm insulated cast iron sleeve bearing (Bearing 6230) is engineered for demanding electrical applications, offering robust insulation to prevent current passage and protect against bearing fluting and pitting. This precision component features an approximate outer diameter of 278.3 mm (10.956") with a tight tolerance of ±0.05 mm, ensuring a secure fit in housing bores. Available in multiple sleeve lengths—70 mm, 80 mm, 90 mm, 100 mm, and 110 mm—it provides flexibility for various installation requirements. Constructed from high-quality cast iron, the sleeve delivers durability and reliable performance in environments where electrical isolation and mechanical strength are critical.
