Product features

1. BC series heavy-duty transmission helical gear box is a right angle shaft heavy load industrial gearbox designed as hard teethface helical gear. The period of designing and manufacturing are shorter because of the blocking design.
2. The feature is compact construction, steady running. It can bear huge road of industry, insteaded of early international standard gearbox.
3. The products have been mainly used in heavy industrial fields, such as mine, petrochemical, electric power, metallurgy etc.
