S worm gearbox

Precision worm gearbox that is maintenance-free and resistant to impacts, shocks, and vibrations. 9 sizes from 40 to 250. Gear ratios from 5:1 to 83:1. Maximum torque up to 13,700 Nm. Maximum speed 3000 rpm. Rotational backlash < 30 arcmin, reduced < 6 arcmin. Cast iron housing. Optionally splash-proof, dust-tight, corrosion-resistant, and explosion-proof.

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.

Optional Versions of S Worm Gearboxes
