Wormwheel High Ratio Reduction Gearboxes

Wormwheel High Reduction Gearboxes

Ondrives.US’ PP series double reduction worm gearboxes are, essentially, two reduction gearboxes in a single unit, with parallel input and output shafts. They feature dual ball bearings on all shafts and permanent lubrication for years of dependable performance, even in nonstop or high cycle operation. Machined, one-piece aluminum block housings and steel internals make the double reduction worm gear reducer tough enough for your most demanding applications.
