TAIXING
The R Series Inline Helical Gear Reducer is a premium power transmission device engineered with modular design as its core, developed by TAIXING to meet diverse industrial needs. This gear reducer stands out for its flexible combinations, multiple mounting types, and optimized structural design, making it a reliable choice for various heavy-duty and precision applications. With an output torque of up to 18000N.m, rated power ranging from 0.18kw to 160kw, and an input speed limited to less than 2000r/min, it delivers efficient speed reduction while maintaining exceptional stability. Crafted with high-quality materials—including cast iron housing, 20CrMnTi ground gears, and 40Cr carburized-quenched shafts—the R Series Gear Speed Reducer ensures long service life and consistent performance in harsh industrial environments. Currently, 200 units are in stock, ready to fulfill urgent order requirements.

The modular structure of the R Series Inline Helical Gear Reducer enables countless combinations of mounting types, input forms, and structural configurations. This flexibility allows it to adapt seamlessly to different installation scenarios, reducing customization costs and shortening delivery cycles for customers.
The cast iron housing provides robust protection and excellent heat dissipation, while the 20CrMnTi grinding gears ensure precise meshing and minimal wear. The 40Cr shaft undergoes carburizing and quenching treatment, enhancing its hardness and toughness to withstand high torque and heavy loads. These quality materials lay the foundation for the reducer’s long-term reliability.
Despite its compact size, the R Series Gear Reducer boasts impressive strength, making it ideal for installations with limited space. Its compact design not only saves floor space but also simplifies integration into existing production lines, improving overall equipment layout efficiency.
Equipped with precision-ground helical gears, the reducer operates with low noise, creating a quieter working environment. It achieves a transmission efficiency of 96% for 2-stage models (ratio: 5-24.8) and 94% for 3-stage models (ratio: 27.2-264), minimizing energy loss and reducing operational costs.
The R Series Inline Helical Gear Reducer offers a large radial loading capacity, with an axial load capacity of up to 5% of the radial load. This feature allows it to handle heavy-duty applications such as conveyor systems and mining equipment, where high radial forces are common.
