Notice for ordering:
1) when ordering,please refer to the details of the products and tell us the exact type your need according to your requirements,like input speed,output torque,configuration,installation,etc:the installation position of the products in the order should accord with your actual needs,otherwise, it will result in oil leakage, which will impact the serving life of the products negatively.if there is special requirement to the installation position,please stress it and inform us.
2) to attain the excellent state of the variators, the common working speed should be chosen in the middle position,instead,it ismot appropriate to choose in the positions of min,or max.speed
3) if your requirements of worm gearbox or speed variator are different from shte standard products as in the catalogue,like:some portion that should be customized or mounted with special motors,please inform us in advance
