The 215 mm steel sleeve bearing, commonly paired with bearing numbers 6224 and 6320, is engineered for robust electrical and mechanical applications requiring reliable insulation and durability. This precision-machined sleeve features an approximate outer diameter of 222.3 mm (with a tolerance of ±0.05 mm) and is available in multiple lengths, including 60 mm, 70 mm, and 80 mm, to accommodate various installation requirements. Constructed from high-quality steel, the sleeve ensures excellent dimensional stability and resistance to wear, making it ideal for use in motors, generators, and industrial machinery where electrical isolation and long service life are critical. Its precise fit and durable construction help minimize vibration and noise while supporting high rotational speeds and loads in demanding environments.
