Numeric ID	18460
Value Type	PMString

For tapered roller bearings, the cone angle of the rollers can be considered as follows:

Internal estimation: The cone angle is determined so that the position of the cone tip of the roller matches the position of the cone tip of the inner ring.
Not considered: The roller is considered to be cylindrical. In this case, the on-board force is zero.
User specified: The specification corresponds to the double cone angle 2*epsilon of the roller. Epsilon is the angle between the roller axis and the raceway.
