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.
