SG 155

SG planetary gearboxes are available in two series:

SG – economy line (SG050, SG070, SG090, SG120 and SG155)

Economy line of SG series represents cost-effective solution for all kind of precise industrial applications. Backlash of SG economy gearboxes is from 8 up to 19 arcmin according to the size and number of gearbox stages.

SG – supereconomy line (SG040, SG060, SG080, SG115 and SG160)

Supereconomy line of SG series is designed mainly for precise applications with low load of gearboxes. Backlash of SG supereconomy gearboxes is from 6 up to 22 arcmin according to the size and number of gearbox stages.
