Planetary Gearboxes manufacturers

Pingyao XINKAI in Shanxi supplies QJ/QY crane reducers, YN permanent-magnet semi-direct drives, modular replacement units and other heavy-duty industrial transmissions. Match the machine load cycle, shaft interfaces, housing construction and agreed acceptance testing before selecting a frame.

Guangdong Siggear Transmission Intelligent Technology develops compact gearboxes and geared motors. The official catalogue includes distinct 22 mm and 28 mm metal planetary gearbox models, SG-PG22 and SG-PG28. Both pages publish stage-by-stage ratio, permissible load and efficiency tables as well as the installation envelope and input-speed limit. These are miniature gearboxes for actuator and geared-motor integration, not industrial heavy-duty reducers. The buyer should choose a diameter, stage count, duty point and motor interface before using the source tables; the four-stage maxima should not be paired with one-stage efficiency values.

Jiangxi Ruiding Precision Transmission lists several planetary reducer architectures on its official site. The AF family uses helical gearing for precision servo transmission, while PSE is a straight-tooth planetary family. Their separate catalog images include model codes and performance tables with frame, ratio, rated output torque, input speed, backlash grade, temperature and enclosure class. A buyer can compare specific frame-and-ratio cells instead of combining unrelated series maxima. The company also publishes dimensions and application categories, including CNC equipment and industrial automation. The source data below retain only clearly legible official figures; request the current drawing for a selected motor interface.

Zhejiang Beitto Transmission Technology presents a range of precision planetary and harmonic reducers on its official site. AHB and AHL are two distinct inline planetary series with separate housing-size lists and standard backlash grades. The company-hosted catalog images include model-code diagrams, reductions for one- and two-stage builds, cutaway views and product photographs. AHB is the tighter-backlash choice in the two documented catalog sections; AHL offers a different size envelope. The figures are series selection data, not a guarantee that every frame and ratio has the same rated torque. Buyers should request the relevant frame sheet and a motor-adapter drawing.

TECHMECH is the gearbox brand presented by Wuxi Tengma Precision Transmission. Its official product catalogue covers multiple precision planetary series, including the right-angle TST and inline TF designs documented here. The pages publish output-frame sizes, ratio choices and backlash figures, allowing a buyer to narrow a configuration before asking for a dimensional drawing. TST uses a right-angle layout and can be paired with another gear stage; TF is an inline precision reducer designed for smooth servo-drive operation. Each series must be specified by frame and stage arrangement rather than combining limits from separate configurations.

Dongguan Tianyi Precision Electromechanical is identified on the Tianyi group website, which presents spindle motors, servo motors and planetary gearboxes. Its reducer catalog distinguishes standard spur families from higher-precision helical families, right-angle units, flange-output units and rotary platforms. The two product pages below retain the official design and efficiency information while avoiding a false model-level torque claim. Some selector choices on the website have different precision limits from the family introduction, so the exact frame, stage and grade require confirmation. The group lists several member companies; confirm the manufacturing and contracting entity for the selected gearbox when requesting a quotation.

Zhejiang Tongyu Variable-Speed Machinery publishes precision transmission products under its TONGYU/JMC identity. The TAB and TAD precision planetary families use helical alloy-steel gears with surface hardening and precision grinding. The official pages distinguish the number of available frame sizes and the single- and double-stage ratio selections for each family. Both pages state a maximum rated torque of 2,000 Nm across the range, without a frame-by-frame rating table. This profile therefore keeps that value at series level. For a servo-axis quotation, supply the motor flange, shaft dimensions, acceleration cycle and permissible lost motion so the manufacturer can identify the exact assembly.

Changzhou Nanpeng Machinery publishes planetary gearboxes under the DESBOER brand. Its NB inline and NBR right-angle families have distinct installation layouts and separately documented rating tables. Official catalog sheets cover ratio-dependent torque, rated and maximum input speeds, precision grades, bearing loads, efficiency, mass and operating temperature. The examples below use NB060 and NBR090, with single-stage torque values mapped to individual ratios. Precision-grade limits are kept separate from generic marketing claims. Provide the full motor designation, required output interface and dynamic load profile when requesting a selection; a shared ratio does not establish mechanical interchangeability between NB and NBR.
