Radian measure

Series for the Trigonometric Functions. In the following formulas, all angles must be expressed in radians. If D = the number of degrees in the angle, and x = its radian measure, then x = 0.017453Z7.

The volume of the wear particle trap must be designed such that the wear particles from the overall contact zone can be collected. As a rule, the volume can be calculated from the radian measure of the contact angle, multiplied by the bearing width and the permissible wear height.
