A planetary gearbox shares load across several planet gears. Confirm nominal and peak torque separately, together with ratio, input speed, backlash and mounting dimensions.

ManufacturerProduct focusProfileActions
JIEHangzhou, Zhejiang, ChinaHelical · Planetary · Worm · Bevel

JIE supplies industrial gearboxes, planetary drives, worm reducers and geared motors. Its WP worm-reducer documentation distinguishes several shaft arrangements and frame sizes. The selected variant, output shaft position and installation drawing should be checked together, especially when replacing an existing reducer.

KOFONHuanggang, Hubei, ChinaPlanetary · Harmonic

KOFON supplies precision planetary and harmonic transmission products, with additional drive ranges for engineering machinery. The FG090 planetary model provides documented ratio-specific torque and backlash data. Buyers should match the catalog configuration to motor dimensions, installation orientation and the required motion duty.

WANSHSINChangsha, Hunan, ChinaPlanetary · Worm · Helical · Harmonic

WANSHSIN manufactures geared drives and precision transmission products in Hunan. Documented families include WVRB planetary reducers, WSHD strain-wave reducers and WRA geared drives. Its planetary catalog separates frame size, ratio and precision grade, while the strain-wave data distinguishes rated, start-stop and momentary torque.

NewstartZibo, Shandong, ChinaPlanetary

Newstart develops precision planetary transmission products in Zibo, Shandong. Its AB series is intended for servo-driven machinery and automation. Published model tables distinguish frame size, ratio and precision grade; verify the motor flange, allowable input speed and the backlash grade required by the machine.

DONLYNingbo, Zhejiang, ChinaHelical · Planetary · Bevel · Worm

DONLY supplies industrial gear units, geared motors and application-specific transmission systems. Its DLP planetary product family serves compact high-torque drive applications. The catalog offers multiple frame sizes and reduction ratios; selection should include duty, thermal capacity, shaft loads and mounting arrangements.

TailongTaizhou, Jiangsu, ChinaHelical · Planetary · Cycloidal

Jiangsu Tailong supplies industrial reducers and precision transmission products. The BXJC cycloidal series provides a documented starting point for robotic and automation applications. Compare individual frame sizes, ratios and output torque ratings in the manufacturer catalog; dimensions and operating conditions need confirmation for the selected assembly.

GUOMAOChangzhou, Jiangsu, ChinaHelical · Cycloidal · Planetary · Worm · Bevel

Jiangsu Guomao manufactures geared motors, cycloidal reducers and industrial gear units in Changzhou. Its catalog covers BLD/BWD cycloidal drives, GR helical geared motors, HB industrial gearboxes and application-specific planetary drives. Select the complete model and number of reduction stages before comparing published series limits.

Dongyu HydraulicsZhejiang, ChinaPlanetary

Planetary reduction and hydraulic rotary drive products.

Build a comparable request

A planetary gearbox shares load across several planet gears. Confirm nominal and peak torque separately, together with ratio, input speed, backlash and mounting dimensions.

Operating requirements

State input speed, target output speed, running torque, repeated peak load and the motion cycle. Include temperature, operating hours and shock loading.

Mechanical interfaces

Share the motor flange, shaft details, mounting orientation and available space. Request a drawing for the exact model and ratio proposed.
