SGK Series
Superior Gearbox SGK-Series helical-bevel gearmotors contain high
torque density with the highest efficiency available in a right-angle
design. Instead of losing energy via the sliding friction of a worm
gear, the K-series uses much lower rolling friction of helical and
bevel gears. The result is minimum heat and maximum energy
savings to the end user.
