Bearings

- Functions:

• Support radial load
• Support thrust or axial loads
• Secure the cone on the leg

- Supporting loads is achieved by outer and nose bearing

- Ball and friction bearings secure the cone on the leg

- Two different bearing are available: antifriction and friction

- Antifriction bearings or roller are two types: Roller-ball-roller (RBR), and roller-ball-friction

- RBR, nose roller; intermediate ball; and outer roller

- The ball secure the cone

- Size influenced by journal angle and cone size

- RBR suffers from spalling of the races of the pin

- RBR bit have short life than Friction Bearing Bit

- Normally used with bit with diameter greater than 12.25 in with adequate space and in situation where high rotary speed is required
