Electromagnetic brakes, back stops, clutches, couplings and other mechanical devices can be incorporated in the design to give a complete drive unit.
- Structures: horizontal foot-mounted, vertical mounting, and outputs can realize solid output shaft, hollow output shaft;
 
- Gears and gear shafts made of high-quality low-carbon alloy steel 25CrMnTi, output shaft made of alloy steel 40Cr, the gearbox housing made of high-strength casting iron HT250, may also adopt better material as requested;
 
- High efficiency up to 98%per stage, low noise <70-80dB, and temperature rise <40-50, and high precision grade up to 6 or better of ISO1328;
 
- Gears and gear shafts through carburizing and quenching then advanced fine profile grinding process to improve stability and transmit power more efficiently, gearbox housing through aging treatment then annealing to relieve stress twice, therefore the bearing capacity very high;
 
- Best China bearings used on products, may apply other bearings like SKF, NSK and FAG, and double-lip oil seal make sure no oil leak;
 
- May custom different models according to clients' requirement.
 
- Every gearbox 100 percent tested prior to delivery;
