42mm Precision Planetary Reducer | High Torque & High Rigidity, Stable Heavy-load Transmission

Core Advantages

• High Precision & Ultra-low Backlash Adopts 20CrMnTi alloy gears with carburizing, quenching and precision grinding treatment, featuring smooth tooth surface and high meshing accuracy. Single-stage backlash ≤8 arcmin and double-stage backlash ≤12 arcmin, completely eliminating transmission clearance and positioning deviation. It ensures accurate and stable repeated positioning, meeting the high-precision requirements of frequent start-stop, reciprocating motion and precise alignment of automation equipment.
• High Rigidity & Excellent Heavy-load Resistance Equipped with a thickened planetary carrier and balanced force-bearing transmission structure, multiple gears mesh synchronously to disperse pressure and significantly improve overall rigidity. It effectively resists impact force caused by equipment start-stop and sudden load changes. The maximum output torque reaches 20N·m. Compared with ordinary reducers of the same specification, it has upgraded heavy-load performance and fatigue resistance, maintaining stable operation without deformation or stalling under long-term heavy load.
• High Efficiency & Ultra-long Service Life Optimized gear profile and transmission ratio ensure smooth meshing with running noise ≤55dB, no abnormal vibration or noise at low and high speeds. The maximum transmission efficiency reaches 97% with extremely low power loss and superior energy-saving performance. Equipped with high-quality high-speed bearings and long-term high-temperature resistant grease, it operates stably in a wide temperature range of -20℃~+90℃. With a dustproof and fully sealed structure, its service life reaches 12,000 hours with minimal maintenance.
• Full Gear Ratio Coverage & Strong Universality Modular design provides comprehensive gear ratio options: 1-stage (3.7/5.2/10), 2-stage (15~50), 3-stage (60~200), adapting to diverse working conditions of low-speed high-torque and high-speed high-precision operation. Standard flange mounting size with universal hole positions enables simple installation and strong compatibility, which can directly replace most mainstream reducers of the same specification on the market.
