Helical-worm Gearmotor S Series
Simple, practical and discrete.
K series (three-stage).
SEW-EURODRIVE helical-worm gear units are helical/helical-worm combinations, so they are more efficient than normal helical-worm gear units. Due to their outstanding efficiency, these drives can be used in every industrial sector and tailored to individual torque and speed requirements. The reduction ratios afforded by the helical-worm gear stage and the low noise levels during operation make these gearmotors ideal low-cost solutions for simple applications.
Features
- Economical operation
- Low noise
- High permitted overhung loads
Available versions
- Foot-mounted or flange-mounted
- B5 or B14 Flange-mounted
- Solid or hollow shaft
- Hollow shaft with keyed connection, shrink disc, splined hollow shaft or TorqLOC®
