• 4 types of tricone drill bit bearings and how

    when learning about tricone drill bits, it is important to note that when the cones of a tricone turn, the bearings act as a buffer. the bearings allow you to drill for longer and deeper by pushing the tricone drill bit to its full potential. there are four main kinds of bearings that allow the tricone to function. they different types of tricone drill bit bearings we go over are open roller
