The 290 mm insulated cast iron sleeve bearing compatible with 6038 and 6232 bearings features an outer diameter of approximately 288-290 mm, an inner diameter of 190 mm, and a thickness around 2.75 to 3 mm. It is constructed from durable cast iron with insulation properties, designed to support loads up to 1150 lbs while reducing wear and vibration. The bearing sleeve provides a robust fit for deep groove ball bearings such as the SKF 6038 MC3, which has a width of 46 mm and is made from high-strength rolling bearing steel. This combination ensures reliable performance in heavy-duty industrial applications requiring precise fit and durability.
