Ruiding Precision Transmission

PSE Straight-Tooth Planetary Reducer

The PSE catalog page describes a straight-tooth planetary reducer, separate from Ruiding’s AF helical design. The official model code lists PSE042, PSE060, PSE090, PSE120 and PSE160 frames with one-stage ratios of 3 to 10 and two-stage combinations up to 100. The performance table is frame-specific: PSE060 at 3:1 has 18 Nm nominal output torque, while the same frame’s nominal input speed is 3,000 rpm. One-stage efficiency is stated as at least 96 percent and operation is specified between minus 10 and plus 90 degrees Celsius. The P1 one-stage backlash row varies by frame, so do not assign one precision figure to every PSE. Check the exact input flange and output-shaft drawing.

Ruiding Precision Transmission

AF Helical Precision Planetary Reducer

AF is Ruiding’s helical-tooth precision planetary reducer family. The manufacturer’s official catalog image lists AF060, AF090, AF115, AF142, AF180 and AF220 frames with one- and two-stage ratio selections from 3 to 100. Its table makes torque conditional on both frame and ratio: for example, AF090 at 3:1 is listed at 130 Nm nominal output torque. It also gives one-stage efficiency of at least 95 percent, operating temperature from minus 10 to plus 90 degrees Celsius, and IP65 enclosure class. Backlash differs by precision grade and stage; the P1 one-stage row is no more than 3 arcmin. Select the exact frame, ratio, grade and motor adapter before comparing load capacity.

BEITTO

AHL Precision Planetary Reducer

AHL is a separate Beitto inline planetary family with a different frame-code sequence from AHB. Its official catalog section lists 050, 070, 090, 120, 155 and 205 sizes. The model-code diagram gives one-stage reduction of 3 to 10 and two-stage reduction of 15 to 100. The AHL features page states standard backlash of 5 arcmin for the described grade. It also depicts helical gearing, a needle-roller-supported output arrangement and an adapter-bushing motor connection. Those catalog values narrow the choice but do not identify a torque limit for any particular frame. Request the chosen AHL size, ratio, shaft dimensions and load table for a servo-driven machine.

BEITTO

AHB Precision Planetary Reducer

AHB is Beitto’s helical planetary reducer family for servo-motor installations. The company-hosted catalog names sizes 042, 060, 090, 115, 140 and 180. Its model-code page lists reductions of 3 to 10 in one stage and 15 to 100 in two stages, while the features page states standard backlash of 3 arcmin for the described configuration. A cutaway drawing shows the planetary gearset, output shaft and motor connection. The catalog also describes needle-roller bearings, anti-separation grease and installation in any orientation. AHB should be selected by housing size, ratio, backlash grade and motor adapter; request the frame-specific torque and load table rather than treating the ratio envelope as a capacity rating.

SIGGEAR

SG-PG22 22 mm Metal Planetary Gearbox

The SG-PG22 is a separate 22 mm diameter miniature planetary gearbox in Siggear’s catalogue. Its official table shows one- to four-stage configurations, with one-stage ratios of 3.5, 4 and 4.75 and rated permissible load of 8.0 kgf-cm for that one-stage arrangement. The continuous input-speed ceiling is 8,000 rpm; unloaded backlash is stated as no more than 1.5 degrees. The 22 mm envelope and lower one-stage permissible load distinguish it from SG-PG28, so dimensions and torque cannot be transferred between them. Select the stage count, shaft interface, radial and axial load, and working temperature for the intended geared-motor assembly.

SIGGEAR

SG-PG28 28 mm Metal Planetary Gearbox

SG-PG28 is Siggear’s 28 mm diameter miniature metal planetary gearbox. The official specification table separates one through four stages: for example, one stage is listed at ratios 3.83, 4.4 or 5.25 with 20.0 kgf-cm rated permissible load and 90% efficiency, while the four-stage version is longer and has different permissible load and efficiency. Its continuous maximum input speed is 8,000 rpm, unloaded backlash is at most 1.2 degrees and working temperature is minus 40 to 120 degrees Celsius. These values describe the SG-PG28 family under the maker’s stated conditions; request the exact shaft, bearing-load and duty specification for a motor pairing.

TECHMECH

TF Precision Planetary Gear Reducer

The TF series is a precision planetary reducer intended for smooth motion under demanding axial or radial loads. TECHMECH’s product page gives output sizes of 60 to 180 mm and lists single-stage ratios of 3, 4, 5, 6, 7, 8 and 10, with further ratios from 15 to 200 for multistage configurations. Its stated minimum one-stage backlash is at most one arcminute; no complete two-stage backlash number is printed in the source text, so that value needs a model drawing. The maker names AC servo, DC servo, stepper and hydraulic motors as possible drive partners. Verify the motor adapter, bearing load and frame rating for the actual duty point.

TECHMECH

TST Precision Planetary Gear Reducer

The TST is TECHMECH’s right-angle precision planetary series. The official product page identifies output sizes from 75 to 240 mm and lists direct ratios of 1, 2, 3, 4 and 5. A separate gear-reducer combination can extend the reduction to 500:1; that figure describes the combined arrangement, not every single TST unit. The maker describes precision-ground gearing, multiple machined mounting surfaces and installation in any orientation. Choose the output frame and combined or direct drive layout before checking backlash, service life and lubrication details in the current catalogue. A model drawing is needed for shaft and flange fit.

WEILI Transmission

Planetary Slewing Gear Reducers

Weili’s slewing reducer is intended for the rotary mechanism of construction machinery. The official product page documents a planetary reduction arrangement and lists the available ratio and maximum-output-torque envelopes. A slewing-drive quotation should include the driven ring gear, allowable pinion loads, required rotation speed and the full acceleration and stopping cycle. Maximum catalog torque is not a continuous-duty rating and does not independently establish the capacity of the whole slew bearing or machine. Match the selected hydraulic motor, brake and installation interface to the manufacturer’s drawing and request an application-specific mechanical calculation.

WEILI Transmission

Planetary Winch Gear Reducers

Weili’s winch reducer drives a cable drum through a multistage planetary gear train. The manufacturer describes a compact construction, an integrated parking brake and compatibility with several variable- and fixed-displacement hydraulic motor series. Its ratio envelope is 26–420 and the published maximum-output-torque envelope is 7.5–325 kNm. Those maximum values must not be presented as continuous rated torque. A winch selection also needs the drum diameter, line pull, reeving arrangement, speed cycle and braking duty. Confirm the complete motor/reducer/brake assembly and the manufacturer’s load calculation before using it in lifting equipment.

NUODUN

NDP001 Coaxial Planetary Reducer

The NDP001 rating sheet is published within Nuodun’s ND-LDB5-AM80B5 product documentation. This page extracts the one-stage NDP001L1 configurations at 1,400 rpm input. Actual ratios differ from the nominal selection labels: for example, the nominal 3.55 entry is listed as 3.577 actual ratio, with 125 Nm output torque and 391 rpm output speed. The sheet also gives a 3 kW thermal-power value for the one-stage group. Thermal capacity and mechanical torque are different checks. The configurations here retain the actual ratios; confirm the motor interface, bearing loads and thermal operating conditions with the manufacturer.

TIANYI

High-Precision Helical Planetary Gearboxes

Tianyi’s high-precision planetary page describes helical planet and sun gears, an integrated carrier/output shaft and a clamping input connection. The catalog identifies SCM415/420 alloy steel and DIN6 gear accuracy. Its stated efficiency exceeds 97% for one stage and 94% for two stages. The family introduction advertises standard and customized backlash levels, but individual selector entries vary; the ordered frame and precision grade must therefore be checked explicitly. Use the official motor interface and rating sheet to establish torque, input speed and allowable bearing loads rather than applying a headline precision value to every size. The manufacturer image illustrates the TB variant within this family.
