*The dynamic friction torque, Td, is measured at a relative speed of 100 min-1. Depending on the initial torque characteristics, break-in to condition the engaging surfaces may also be required. *The rotating part moment of inertia for shaft input is the value with one armature type-5.

*The input/output keyways are old JIS standard class 2 while the key is old JIS standard class 1. Note that the keyway dimensions of the unit hub part do not conform to JIS standards. Check them on the dimensions table above. *When inserting pulleys or the like onto input/output shafts, use the supplied insertion set. *The 121-25-10G base is a casting.
