All Rights Reserved • Roller Cone Bits; – Bearing Assembly: • A bearing is a device that sits between the cone and its attachment to the leg of the bit to reduce the force of friction as the cone rotates. • Roller cone bit bearings must operate under severe conditions temperature and loads, • Roller cone bits use three types of bearing in the bearing assembly: – Ball bearings; – Roller bearings; – Journal bearings. • Some roller cone bits use all three and some use only roller and ball bearings.
