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
