Product Description
Bearing steel rolling mill (or refers to the cold drawn) for seamless steel tubes, rolling bearing collar with average manufacturing. The steel for 25-180 mm diameter and wall thickness of 3.5-20 millimeter, ordinary precision and accuracy. Bearing steel is used for manufacturing ball, roller bearing steel and rings. Bearing in work is under great pressure and friction, so have high demands bearing steel and hardness and resistance, and high elastic limit.
