The 170 mm insulated cast iron sleeve bearing for bearing sizes 6022, 6219, and 6316 features an approximate outer diameter of 177 mm (6.969 inches) with a tolerance of ±0.05 mm (0.002 inches). It is designed as an oversized cast iron sleeve with a length option typically around 50 to 80 mm, providing robust insulation and durability for heavy-duty applications. This sleeve bearing offers precise dimensional compatibility for the specified bearing series, ensuring reliable fit and electrical isolation to prevent current flow through the bearing, which helps reduce fluting and pitting damage. Its cast iron construction delivers strength and wear resistance for extended service life.
