SGF Series Parallel Shaft Helical Gearmotors

 

The Superior Gearbox SGF Series parallel shaft helical gearmotor is the ideal drive for tight spaces. This compact drive, with its multiple mounting configurations and shaft designs, is a rugged alternative to right-angle gearmotors.  Units are available as shaft output or as hollow bore / shaft mount designs.
