1. Specify profile by mean diameter "Dm", andeccentricity value "e".

2. Shaft tolerance is based on class g6 forsliding fit, other classes can be used for transition or press fit applications.

Designation: Dm g6/e ex. 2.00" g6/.070"

3. Bore tolerance is based on class H7.

Designation: Dm H7/e ex. 2.00" H7/.070"

4. Profile pressure angle B varies between 12

and 14 for all sizes. Use 13 for calculations.
