R type gear reducer is an ideal choice for high output speeds or low weight. Always with a high level of efficiency, our helical gear units offer an optimum ratio between output torque and installation space. This means: a helical gear unit almost always fits your application.
helical reducer has the features of high versatility,good combination and heavy loading capability, along with other merits such as easy to attain various transmission ratios, high efficiency, low vibrationand high permissible axis radial load. This series can not only be combined with various kinds of reducers and variators and meet the requirements, but also beadvantage of localization of related transmission equipment.
