  • Trunnion Bearing Assembly Ball Mill Rod Mill

    Ball Mill PINION SHAFT BEARINGS. Pinion shaft bearings are of the SKF anti-friction type mounted in a common twin bearing assembly. Bearings are fixed in place so that the pinion shaft of the mill is always in alignment with the drive components. V-belt driven mills are furnished with an outboard bearing of similar construction.
