If You‘re Replacing an Existing Gearbox


Many first-time buyers are actually replacing old or faulty equipment, which may come from brands such as SEW, Nord, Bonfly, Rossi, or others.


Key things to check for drop-in replacement:

Same mounting dimensions – bolt hole patterns, shaft diameter, center height

Same ratio – check the nameplate

Same or higher output torque

Same input flange and shaft size

Same mounting position (M1–M6)

Benefits of choosing an alternative:

30%–50% cost savings

Weeks instead of months lead time

1:1 interchangeable – no equipment modification needed
