Soft-tooth gearboxes are not recommended as they are to be outdated, even though, because of its big volume (to ensure safety and reliability) and low price when compared to hardened-tooth gearboxes, they are still widely used in many industries like mining, cranes, textile and light-industry, etc. On the other hand, bis module for gears guarantee that gearbox shockproof.

 

- Gears made of high-quality low-carbon alloy steel 35CrMo, shafts made of steel C45 of DIN (or 1045 of ASTM, the gearbox housing made of gray casting iron;

 

- Gears' module is very big, to make sure gearbox impact resistant enough

 

- Gears and gear shafts through quenching, gearbox housing through aging treatment then annealing to relieve stress twice;

 

- 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;

 

- Every gearbox 100 percent tested prior to delivery;
