S Worm Gearbox

Features of S Worm Gearboxes

Precision-built and robust offset gearboxes.
Quiet operation and resistant to impacts.
Consists of a worm shaft (single- or multi-start) and a worm wheel with vibration-damping properties.
Due to its operating principle, it allows high gear ratios in a single stage.
Dynamic and static self-locking capability depending on gearbox size and ratio.
Anti-vibration properties – worm wheels dampen vibrations.
Offset between input and output shafts.
Low-backlash design down to < 6 arcmin.
Maintenance-free – no servicing required.
Housing made of cast iron.
Ambient temperature range: -10 to +90°C.
NBR seals.
Protection class IP54.
Wide speed range from 0.1 to 600 rpm.
Dynamic and static self-locking possible depending on gearbox size and ratio.
