Dental Tool Bearings

Dental Tool Bearings

There are two basic types of dental ball bearings depending on the type of work that the tool is designed for. The first type is the Radial Bearing and the second type is the Thrust Bearing. Radial Bearings are designed for working in deep grooves and for angled dental surfaces. Radial Bearings have an inner ring, an outer ring, a series of balls and typically a cage to contain the balls. The second type of dental ball bearing is the Thrust Bearing. This type of bearing is used for side or thrust loads. Thrust Bearings use balls, rollers or needles. In addition to these working surfaces they also typically have a ring and a seating surface.
