Author: HUIGUANG × CHENGFA Transmission Technical Team · Updated: 2026-08-13

CHENGFA H/B series industrial gearboxes address engineered industrial drives. H series uses a parallel-shaft arrangement, while B series uses a right-angle bevel-helical arrangement. Begin with the machine shaft layout, then verify output torque, shaft loads, continuous duty, heat and interfaces.
An enquiry should include input power and speed, required output speed, actual load, operating hours, starts, shock, radial and axial loads, installation drawing, ambient temperature and cooling conditions. State the load position and direction when a pulley, chainwheel, drum or long shaft is connected.
H/B product ownership belongs to CHENGFA. Ratio, torque, thermal capacity, dimensions and permissible loads must come from approved model data. Contact sales@chinfar.com.
