Duff-Norton Mitre Boxes

Power transmission component

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

Features

  • 98% average efficiency ratings.
  • Carburized and case hardened bevel gears.
  • Alloy steel input/output shafts for greater strength.
  • Anti-friction bearings on all shafts.
  • MB-4 and MB-8 models come with lifetime lubrication, stainless steel shafts and aluminum housings.

Our mitre boxes 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.
