Journal bearing
- The bearing load carrying surface
- Journal angle is the angle formed by a line perpendicular to the axis of the journal and the axis of the bit
- Magnitude affect the size of the cone
- Increase in angle decrease cone size
- The smaller the angle the greater the gouging and scraping action
- Optimum journal angle for soft and hard rock bits are 33 and 36
