*The 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 the old JIS standard. Check them on the dimensions table above.

*When inserting pulleys or the like onto output shafts, use the supplied insertion set.

*The 122-20-20G base is a casting.
