When the ball mill main bearing works, heat is continuously transferred to the bearing from the hot material and hot gas (drying and grinding) inside the mill, and the contact surface between the bearing journal and the bushing generates heat due to friction. If not eliminated, the accumulated heat will make the bearing temperature rise to destroy the lubrication of the ball mill bearings, the ...

Deep Groove Ball Bearings These ball bearings are the most common type of bearing. These bearings can handle both radial and thrust loads. Due to their low frictional torque, they are suitable for high speeds. In a ball bearing, the load is transmitted from the outer race to the Ball and from the ball to the inner race.
