The 250 mm insulated cast iron sleeve bearing, compatible with bearing numbers 6228 and 6323, is engineered for robust electrical insulation and mechanical durability in demanding industrial applications. This precision-machined sleeve features an approximate outside diameter of 259 mm (10.197") with a tight tolerance of ±0.05 mm, and a sleeve length of 110 mm, ensuring a secure fit and reliable performance. The cast iron construction provides excellent strength and wear resistance, while the integrated insulation layer protects against electrical currents that can cause bearing damage. Ideal for large motors and generators, this sleeve bearing combines high load capacity, dimensional accuracy, and electrical safety for extended equipment life and reduced maintenance.
