High-Efficiency & Large Torque Output:
2-stage transmission efficiency 92%, 3-stage 90%. 20CrMnTi gears deliver 80 - 500N·m torque, outperforming RV series reducers significantly.
All-Directional Flexible Installation:
Aluminum alloy housing allows omnidirectional mounting. Its dimensions are compatible with RV series, enabling direct replacement and easy equipment refitting.
Strong Corrosion & Wear Resistance:
Aluminum housing undergoes anti-corrosion treatment. Gears with 56 - 62HRC hardness resist wear, enduring organic solvent corrosion in chemical scenarios.
Wide Speed Ratio Adaptability:
Ratio ranges 7.5 - 300. Matches different input speeds to output 24 - 188r/min, suiting diverse low-speed transmission needs.
Stable Low-Noise Operation:
Precision-ground gears ensure smooth meshing. The structured housing reduces vibration, realizing low-noise work ideal for quiet food/pharmaceutical workshops.
The full range of products includes motors, input interfaces, output modules, installation forms, etc., which can be personalized designed and manufactured according to customer needs.
We offer multiple color schemes such as RAL7045 (gray), RAL9011 (black), RAL5015 (blue), RAL9003 (white), RAL3014 (purple), etc. Customers can choose the corresponding product color according to their different needs.
Our nameplate is made of stainless steel laser printing technology, which can be customized according to the different needs of customers, especially by adding a product QR code. Scanning the QR code can quickly access product information and sales service information.
Conventional packaging forms include cardboard boxes, pallets, and wooden boxes. We can also customize the outer box packaging according to customer needs.
