RXF Series High Torque Single Stage Helical Gearbox with Flange Mounted
RXF series helical gearboxes are novel reduction transmission devices composed of helical gear reducer and various motors. It has wide transmission ratios, high transmission efficiency, low energy consumption, and superior performance. The gears are processed by a high-precision gear grinding machine. RXF series helical gearbox has its own advantages of high torque, long life, compact design, small size, easy installation, wide ranges of uses, and various installation methods, and it’s suitable for all-around installation configurations. RXF series helical gearbox is the single-stage type of helical gear reducer with a flange mounted, and its ratio is up to 8.65 and its output torque up to 1680N.m.
