Power transmission systems frequently use multiple screw jack arrangements. Such systems commonly use bevel gearboxes to effectively position and equally distribute loads. As the bevel boxes are supplied with 1:1 gear ratios as standard, all motion is synchronous upon system actuation through the main drive shaft.

Duff Norton bevel gearboxes feature a compact design, which eliminates the need for an extended hub. With this design feature the bevel gear is supported by tapered roller bearings on both sides. The result is a higher horsepower rating, increased service-life, improved lubrication, and more flexible mounting compared to other brands.
