HUAKE
HUAKE zero-backlash cycloidal pinwheel speed reducer (RV series) is a high-efficiency, high-rigidity gear reduction solution, purpose-built for high-precision motion control and automation scenarios. Adopting advanced cycloid-pin gear precision meshing technology, this RV cycloidal pinwheel reducer delivers a single-stage transmission ratio range of 7×87 and rated output torque from 35N·m to 6300N·m. With zero backlash and ultra-high rigidity as core advantages, it is fully compatible with servo and stepper motor interfaces, making it the ideal high precision industrial reducer for industrial automation partners requiring stable, precise, and heavy-load transmission performance.
Equipped with a patented cross slider compensation mechanism, this automation control gear reducer achieves zero backlash output, with positioning accuracy ≤1 arc minute and repeat positioning accuracy ±15 arc seconds. The cycloid gear has a tooth profile error ≤5μm, with transmission efficiency ≥90%, far exceeding traditional gear reducers.
Its axial size is 40% shorter than conventional planetary reducers, with a compact modular structure that fits into space-constrained automation equipment. It supports 8 installation configurations, including flange-mounted, shaft-mounted, and foot-mounted, to adapt to diverse equipment layouts.
It delivers 3 times the instantaneous overload capacity, withstanding heavy impact loads without component damage. It has passed 2 million start-stop durability tests in accordance with ISO 6336 standards, ensuring stable performance under 24/7 continuous operation.
With IP65 protection grade, it adopts fully enclosed oil bath lubrication, with an oil change cycle of up to 30,000 hours. It uses low-temperature lithium-based grease, adapting to a working temperature range of -30℃×120℃ and altitudes up to 4000 meters.

This zero-backlash cycloidal pinwheel speed reducer is widely used in high-precision industrial scenarios: six-axis joint drive for industrial robots, rotation units for SCARA robotic arms, indexing of CNC machine tool rotary tables, feed systems for gantry milling machines, wafer handling robots and alignment platforms for semiconductor equipment, steering modules for high-speed logistics sorting machines, stackers for stereoscopic warehouses, and precision transmission systems for new energy battery production lines.
The core cycloid wheel is made of high-purity alloy carburizing steel, with carburizing and quenching treatment to reach HRC58-62 hardness, ensuring exceptional wear and fatigue resistance. The pin gear adopts high-precision bearing steel with mirror grinding treatment, and the reducer housing uses high-strength ductile cast iron or die-cast aluminum alloy for superior rigidity and vibration damping. All core components are processed by 5-axis CNC machining centers, with strict gear accuracy testing and dynamic balance calibration, fully complying with ISO 1328 precision standards.
We provide full-range customization services for industrial automation enterprises: hollow shaft with locking disk configuration, custom flange hole positions and dimensions, anti-corrosion coating customization (PTFE/Ni-P), special transmission ratio design, multi-stage series connection solutions, and motor interface customization for various brands of servo and stepper motors. We also offer comprehensive OEM/ODM services, including brand labeling, custom packaging, and exclusive technical solution co-development, to fully align with your brand and equipment design requirements.
Our RV series high precision industrial reducer is more suitable for high-torque scenarios over 200Nm, with a service life 3 times longer than harmonic reducers, and is specially designed for 24/7 continuous industrial operation.
The backlash can be precisely controlled within 0×5 arc minutes by adjusting the pre-tightening bolts of the end cover with a standard torque value of 28N·m±10%.
Yes, it supports two-stage series connection, with the transmission ratio extendable up to 1×7500. We can provide customized intermediate connection flanges and lubrication systems for series applications.
We recommend using KLUBER ISOFLEX TOPAS L32 grease. The fully enclosed design requires an oil change every 30,000 hours, with 50ml of grease replenished through the grease nozzle every 10,000 hours of operation.
