The cylindrical shape allows the inner ring to have axial movement relative to the outer ring. This is especially important when accommodating thermal expansion, where both rings must be press-fitted. Main use: Large and medium motor, Locomotive, Spindle, Engine, Dynamo, Gas turbine, Gear box, Rolling mill, Shaker and Hoisting and conveying machinery etc.
