Design factors

- Bit design depend on formation properties and hole size
- Legs are same but cutters are different
- Three logs should be equally loaded
- The main design factors are Journal bearing, amount of offset,teeth, bearing and relationship between teeth and bearing

 

Roller-ball-friction (RBF)

- Friction type bearing at the nose
- The inner ball and outer roller as the same as RBR
- The friction consists of a special case-harden bushing pressed into the nose of the cone

- Introduced to overcome the shortcomings of RBR

- Allow thicker cone section

- Larger pin diameter

- Common for bit sizes up to 26"
