Standard right-angle shaft type bevel gearbox of spiral bevel gears for general applications with high performance and high efficiency. Wide variation ranging from small to large capacity, torques up to 5700Nm have proven their versatility and value time by being extremely precise with very low backlash and very low transmission error. Silent, shock resistant, have overload capability and are space saving. Smooth rotation and silent drive possible, and Easy installation. A full lineup from small-size models to large-size models, for a wide range of applications, such as for use with screw jacks to create vertical lifting and lowering mechanisms. They are all of identical design and use and optimised bevel gear geometry that delivers increased torque and high efficiency in a compact and lightweight package. These high performance bevel gearboxes are available in flange, solid or hollow shaft versions. Speed ratio of 1:1, 1.5:1, 2.5:1, 3:1, 4:1 and 5:1 are the actual transmission ratio. The average efficiency is 94%.
