Frequently Asked Questions

What does a 20:1 worm gearbox do?

A 20:1 worm gearbox reduces the input speed by a factor of 20, lowering output speed while multiplying torque at the driven shaft.

What is the advantage of a hollow bore output?

A 24mm hollow bore lets the gearbox mount directly onto a shaft, which helps reduce footprint and can simplify assembly in many machine designs.

What mounting positions can this gearbox be used in?

The SW series supports mounting positions B3, B6, B7, B8, V5 and V6, with B3 being the technically preferred position for lower oil splash, better lubrication and less heating.

Is this gearbox supplied lubricated?

Yes. The gearbox is supplied lubricated for life with synthetic oil and is intended for the mounting positions shown in the catalogue.

What applications is this gearbox commonly used for?

Worm gearboxes like this are commonly used on conveyors, packaging machinery, handling equipment, mixers, feeders, and other industrial systems that need compact right-angle speed reduction.
