1. Efficient and safe operating 2. Compact structure and small volume saves mounting space 3. High load capacity and overload functions give stable transmission with reduced vibration and noise 4. No gap structure of gearbox makes this reducer maintenance free and prevents lubricant from leaking 5. Various linking structures for power input and torque output allows for different mounting methods 6. Low noise and stably running, can adapt long term work condition in terrible environments. 7. Light weight, high mechanical strength 8. Motor mounting, shaft mounting, flange mounting. 9. Rv series is widely used, an ideal choice for modern industrial equipments to realize transmission and control at large speed reducing ratio. Input power 0.06-7.5kw Ratio 5-100 Output torque 0.06-1179n.M. Wood and carton.
