W. C. Branham was industry first - with right angle hollow bore helical gearboxes that package an all ball bearing configuration in a leak-proof, sealed gearcase and pre-lubricated design. The immediate benefits were achieving higher thrust and radial loads, lower operating temperature for greater efficiency, no leakage, and longer service life.

Each gearbox has two helical gears that mesh at 90º to rotate power. They are bi-directional and slide axially along keyed shafts for easy installation. They are also vast improvements over "float or "slide" right angle models made by T-O-M Brand Hamel, MN. Shipped pre-lubricated and installation ready.
