Features

– Can be used in all industries and applications, e.g. in lifts or conveyor applications

– Low loss, two-stage design (helical/hypoid gearing)

– Gearing with infinite fatigue strength, which means the drive is almost wear-free

– Can be combined with all motors from SEW-EURODRIVE

– Energy efficiency:

- Gearing efficiency of more than 90% i low energy consumption

- Gear unit efficiency allows for smaller motors i compact design

- Motor energy efficiency class from IE1 to IE4 can be realized

– Wide range of designs ensures an optimum connection to the customer machine even in critical mounting situations
