The R Series Gear Motor (including core models RXF17, RXF27, RXF37, RXF47, RXF57, RXF67, RXF77, RXF87, RXF97, RXF107, RXF137, RXF147, RXF167) is a premium coaxial helical gear reducer engineered with serialization and modularization design concepts. Developed to meet international technical standards, this gear motor delivers exceptional performance, boasting high transmission efficiency, low energy consumption, and wide adaptability for industrial applications. With a power range of 0.12KW to 160KW and a torque range of 1.4N·m to 23200N·m, it caters to diverse load requirements, while its output speed spanning 0.06 to 1090r/min ensures precise operation. Whether for heavy-duty machinery or precision automation, the R Series stands out as a reliable mechatronic solution, combining robust construction with flexible configuration.
Adopts optimized helical gear transmission, achieving high transmission efficiency of over 95% for two-stage models and 94% for three-stage versions, minimizing energy waste.
Low energy consumption design reduces operational costs, making it an eco-friendly choice for long-term use.
Smooth power transfer with minimal friction ensures consistent performance even under high-load conditions.
Crafted from high-quality forged steel for gears and steel cast iron for the housing, ensuring structural integrity and resistance to wear.
Gear surfaces undergo high-frequency heat treatment, enhancing hardness and extending service life.
Precision machining guarantees shaft parallelism and stable bearing positioning, reducing mechanical failure risks.
Supports multiple mounting types: base type, large and small flange type installations, adapting to diverse equipment layouts.
Flexible input methods: direct motor connection, shaft input, and connection flange input, enabling seamless integration with various power sources.
Modular design allows easy combination (R/R combination) for extended transmission ratios up to 18125, meeting specialized speed reduction needs.
Low vibration and low noise performance create a comfortable working environment, ideal for indoor industrial settings.
High overload capacity (up to 132KW) handles sudden load surges without performance degradation, ensuring operational stability.

RXF27 | 0.18 - 3 | 3.3 - 176.88 | 70 | 8 |
RXF37 | 0.18 - 3 | 3.83 - 186.69 | 135 | 14 |
RXF47 | 0.18 - 5.5 | 3.83 - 199.61 | 215 | 23 |
RXF57 | 0.18 - 7.5 | 3.83 - 195.24 | 400 | 39 |
RXF107 | 7.5 - 45 | 1.44 - 6.65 | 830 | 100 |
RXF167 | 11 - 160 | 1.63 - 6.22 | 18000 | 700 |
Ideal for conveyors, mixers, extruders, and crushers, providing stable power transmission for continuous production lines.
Suitable for heavy-duty equipment in mining, metallurgy, and construction machinery, withstanding harsh working conditions.
Integrates with robotic arms, assembly lines, and precision positioning systems, delivering accurate speed control for automated processes.
Meets the high-precision requirements of electronic component manufacturing and packaging machinery.
Powers hoists, cranes, and forklifts, offering high torque output for safe and efficient material lifting and transportation.
Compatible with conveyor systems in logistics warehouses, ensuring smooth item flow with consistent speed.
Works with pumps, fans, and generators, optimizing energy conversion with high efficiency and low power loss.
Suitable for renewable energy systems (e.g., wind turbine auxiliary equipment) and power distribution machinery.
The R Series supports two-stage (524.8), three-stage (27.2264) ratios, and R/R combinations up to 18125, covering most industrial speed reduction needs.
Yes. When using a user-supplied or special motor, an additional connection flange is required (see page 186 for length specifications) for seamless integration.
Gears are made of high-quality forged steel (heat-treated), and the housing is steel cast iron, ensuring durability and wear resistance.
The robust construction and heat-treated components enable stable operation in moderate high-temperature settings (recommended operating temperature: -10°C to 40°C). For extreme conditions, contact our technical team for customization.
Routine maintenance (lubricant check/replacement) is recommended every 6 months or 2000 operating hours, depending on usage intensity. The durable design minimizes maintenance frequency.
