These are double-clutch/brake units unlike any other that combine two clutches (101-[ ]-15) with a brake (111-[ ]-12) in a compact form factor.They provide high-precision positioning and applied control of complex operations from a single unit. The hub is used as the input for two-stage speed-change/fixed position stopping/high-precision forward-reverse operation. The output shaft is braked when clutch current is shut off and the brake is energized in response.
*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.
