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 damage. This precision component features an approximate outer diameter of 278.3 mm (±0.05 mm) and is available in multiple sleeve lengths, including 70 mm, 80 mm, 90 mm, 100 mm, and 110 mm, ensuring compatibility with a range of motor and generator housings. Constructed from high-quality cast iron, the sleeve provides excellent durability and dimensional stability. Its insulated design is critical for preventing electrical arcing and extending bearing life in environments where stray currents are a concern, making it an essential upgrade for reliable, long-lasting electrical machinery performance.
