PROGEARSIVE’s NU series were developed to meet the demand for a compact, universal mount worm gear speed reducer. It is produced to offer industry unmatched dependability.

Double Reduction

PROGEARSIVE’s double reduction units consist of two single reduction worm gear units. The primary worm gear unit is specially designed to mount integrally on a standard single worm gear unit which forms the secondary stage. Double reduction gear units are made up of same high quality components as single reduction.

Tube Mill

PROGEARSIVE’s tube mill worm gear units use one worm on the power input shaft to turn two gears simultaneously in opposite directions. This gearbox is designed for applications such as cold-form rolling, tube mills, tyre curing press.
