Helical Gear Reducer

R Series Foot Mounted Helical Gear Reducer

R series helical gear reducer adopts an integral casting box, which has good structural rigidity and quickly improves the shaft’s strength and the bearings’ life. As its structure is compact, it saves a lot of space. The installation methods of the R series helical gear reducer include foot installation and flange installation, foot installation type is more widely used. Its average efficiency is 96% for the double-stage type, 94% for the three-stage type, and 85% for the R/R combination type.

As one of the helical gear reducer manufacturers, suppliers, and exporters of mechanical products, We offer helical gear reducer and many other products. Please get in touch with us for details.
