Precision needle rollers have multiple uses in a variety of applications. Needle rollers are mainly used as bearing rolling elements to transmit torque and reduce friction. They can also serve as precision shafts or as precision locating pins. Needle rollers with a controlled contour profile are available to reduce end stresses. special end forms provide performance benefits for specific kinds of applications.

One unique aspect of these critical profiles is that certain areas of the profile must be controlled to tighter tolerances.
