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