WGT R-Series Helical Gear Reducer

As a flagship product of WGT Weigao Transmission, the R-Series helical gear reducer is renowned for its compact structure, high load-bearing capacity and superior transmission efficiency, serving as a core power transmission component in diverse industrial fields. Adhering to stringent manufacturing standards, this series integrates advanced gear technology and robust structural design to meet rigorous operational demands.

The reducer features an integrated cast iron/ductile iron housing with a hardness of HBS190-240, ensuring exceptional structural rigidity and prolonging shaft and bearing service life. Its offset output design achieves high space utilization, integrating two-stage and three-stage transmission in a single housing. Gears are crafted from 20CrMnTi alloy steel, undergoing carburizing, quenching and precision grinding processes, resulting in a surface hardness of HRC58°-62° and machining accuracy of grade 5-6, which enhances load capacity by 40%.

With a power range of 0.18-160 kW, torque output of 85-18000 Nm and speed ratio of 3.33-289.74, the series offers versatile configurations including R, RF and RX models. The average transmission efficiency reaches 96% for two-stage, 94% for three-stage and 85% for R/R combinations, with noise controlled at 60-68 dB and vibration ≤20 μm, ensuring stable and energy-efficient operation.

Equipped with 42CrMo alloy steel shafts and high-quality bearings (HRB/SKF) and NAK oil seals, it boasts excellent leakage resistance and a design lifespan exceeding 50,000 hours. Multiple mounting options (foot, flange) accommodate various installation scenarios. It is widely applied in food processing, construction machinery, metallurgy, chemical and environmental protection equipment.

Backed by 100% qualified quality from 66,000+ accumulated units, the R-Series supports OEM customization and is complemented by WGT’s 3D selection system, delivering efficient and reliable power solutions for global customers.
