Industrial Gearbox Selection Guide | CHENGFA Product Navigation
Author: HUIGUANG × CHENGFA Transmission Technical Team · Updated: 2026-08-07
Start gearbox selection with output torque, ratio, duty cycle, shock load, mounting space and shaft loads. Product names help narrow the options, but they do not replace an engineering check.
| Requirement | Product families to review | Key inputs |
| Modular continuous machinery drive | R/F/K/S | power, ratio, mounting, service factor |
| High ratio, impact or frequent starting | X/B and WB cycloidal | shock level, starts, shaft load |
| Compact right-angle arrangement | NMRV, WP, CWU | efficiency, heat, environment, lubrication |
| Linear lifting | SWL screw jack | load, travel, speed, synchronization, safety |
| Industrial heavy-duty configuration | H/B and DCY | torque, shaft system, thermal duty, interfaces |
| Coaxial, high-ratio, high torque density | P-series planetary | service conditions, heat and installation space |
| Water treatment and industrial mixing | agitator and matched drive | medium, impeller, speed, shaft and sealing |
| Existing-machine retrofit | custom replacement engineering | nameplate, drawings, interfaces and acceptance |
The same “high-ratio” requirement can lead to cycloidal, worm or planetary solutions with different efficiency, shock tolerance, mounting, maintenance and cost implications. Send the known operating data to sales@chinfar.com so the product category can be identified before a detailed model is proposed.
