We provide cutting-edge cycloidal gear solutions.
Our innovative cycloidal pinwheel reducer employs a planetary transmission principle and cycloidal pinwheel tooth meshing, finding extensive application across various sectors including textile printing and dyeing, light industry food production, metallurgy, mining, petrochemical, lifting, and transportation, as well as construction machinery drive and speed control systems.
Our factory's cycloidal reducers guarantee superior quality, reliable performance, and a comprehensive range of specifications at competitive prices. Committed to our principles of "sincerity and credibility," we prioritize quality first and customer satisfaction, earning trust through reliable performance and significant technical and economic benefits, making us a preferred choice across industries.






Start by identifying your torque requirement (up to 500 Nm), reduction ratio (5:1-100:1), and mounting style (foot/flange/shaft). Consider environmental factors: IP65 seals protect against dust/water, while cast iron housing suits high-temperature or corrosive settings. For vertical/horizontal setups, our 90° right-angle design optimizes space - share your CAD drawings for custom mounting brackets!
Yes! The worm gear's geometry prevents backdriving at ratios ≥10:1, ideal for lifts, conveyors, or static loads. Note: Self-locking is torque-dependent - consult our engineers for high-load scenarios.
Ensure alignment with the motor/output shaft (≤0.05mm ). For hollow-shaft models, use the supplied key and clamping collar. Avoid over-tightening mounting bolts - torque specs are listed in the manual. Pro tip: Run it idle for 30 minutes post-install to check for noise/vibration.
Lubrication is key! Use EP150-220 gear oil (replace every 2,000 hours or annually). Check seals for leaks and housing temperature (≤80°C during operation). No greasing needed - the bath-lubricated design minimizes downtime.
Absolutely! Choose solid/hollow shafts (metric/SAE), flange sizes, or add B5/B14 motor adapters. We offer custom paint (RAL colors), galvanization, and even flange drilling patterns - lead time is 2-4 weeks for bespoke orders.
Worm gears inherently produce more noise (75-85 dB) due to sliding contact. For quiet operation (≤70 dB), opt for our WP-Silent variant with precision-ground gears - ideal for food packaging or medical equipment.
2 years for defects in materials/workmanship, excluding wear parts (seals, oil). Register your product online for extended coverage.
Yes, but monitor temperature! The cast iron housing dissipates heat efficiently, but ambient temps >40°C may require a cooling fan (available as an accessory).
First, check oil level (1/3-1/2 housing height). If oil is black/gritty, replace it. Ensure proper ventilation - blocked cooling fins raise temps. Still hot? Contact us - we'll audit your load calculations.
