BEITTO
Choose the servo reducer by its frame and ordering code.

BEITTO develops planetary and harmonic reducers in Pinghu, Zhejiang. Its AHB and AHL planetary catalogues show why two similarly rated drives can need different mechanical checks: frame dimensions, backlash codes, external loads and emergency-stop limits are part of the selection. Use the official frame sheet to turn a motion requirement into an orderable assembly.

Official planetary catalogue sections

The frame lists are different.

AHB · official product-page image.

AHB · sizes 042 / 060 / 090 / 115 / 140 / 180

The model-code sheet separates single-stage ratios 3–10 and two-stage ratios 15–100. Its example includes S3 and describes a 3 arcmin precision option, with a 1–3 arcmin note. Confirm the exact offered code and measurement condition.

The illustrated architecture uses helical gears and a motor-adapter bushing. Ask for the ordered frame's rated torque and inertia, motor coupling, output shaft and mounting drawing.

Existing AHB specifications →

AHL · official product-page image.

AHL · sizes 050 / 070 / 090 / 120 / 155 / 205

The AHL code sheet also separates single-stage 3–10 and two-stage 15–100 ratios, but its example shows S5 and describes 5 arcmin precision. The family has a different size envelope from AHB.

Use the AHL frame sheet for a replacement check. A comparable output torque does not establish matching mounting holes, pilot, shaft, overall length or motor adapter.

Same i=5 and 29 Nm. Different limits around them.

These are single-stage rows from AHB060 and AHL070. They demonstrate a comparison method rather than recommending an interchangeable replacement.

AHB060 · i=5 · single stage

Nominal output torque: 29 Nm
Maximum output torque: 55 Nm
Emergency-stop torque: 108 Nm
Nominal / maximum input speed: 3,000 / 6,000 rpm
Permitted radial load: 530 N
Permitted axial load: 410 N
Listed single-stage mass: 1.4 kg

AHL070 · i=5 · single stage

Nominal output torque: 29 Nm
Maximum output torque: 55 Nm
Emergency-stop torque: 110 Nm
Nominal / maximum input speed: 3,000 / 6,000 rpm
Permitted radial load: 525 N
Permitted axial load: 405 N
Listed single-stage mass: 1.5 kg

Read the force footnotes before adding a pulley or pinion.

The catalogues relate permitted radial load to nominal input speed, 20,000-hour life, force applied at the output-shaft centre and zero axial load. The axial row separately assumes zero radial load. Do not treat the two numbers as a simultaneous combined-load allowance; give the supplier the actual speed, force positions and duty for a bearing-life check.

Maximum torque and emergency-stop torque are separate columns from nominal output torque. Specify the peak duration, frequency and stopping cycle, and obtain written selection confirmation for the machine's actual load spectrum.

Ordering and acceptance

Put the agreed precision code in the quotation.

The AHL feature page describes 3 arcmin standard backlash, while its model-code page explicitly shows S5 / 5 arcmin. Ask BEITTO to resolve that difference for the offered frame, stage and revision. The ordering code, current drawing and agreed inspection condition should identify what will be delivered.

For either family, specify whether the requirement is gearbox backlash, loaded torsional deflection, output positioning repeatability or complete-machine accuracy. Describe the test torque, direction reversal, temperature and encoder position where relevant.

Resolve the motor connection too.

The coding example ends with motor type. Send the actual motor manufacturer's model and dimension sheet: pilot, flange pattern, shaft diameter, usable shaft length and key/clamping arrangement. Agree adapter, fasteners and installation instructions, including any bushing and clamp-tightening requirements.

Match the brief to the machine's failure mode.

BEITTO's application page lists packaging, laser cutting, printing, gantry robots and photovoltaic equipment. The following questions help turn those named uses into a selection; they are not claims that a particular frame is already qualified for your installation.

Packaging / printing

Indexing, synchronisation and repeated starts

Provide cycle timing, acceleration, cutting/sealing forces, dwell and phase tolerance. State backlash/rigidity requirements and emergency-stop behaviour. Request a repeated-duty selection, not only a static torque comparison.

Gantry / laser axis

Rack or belt forces at their real locations

Provide moving mass, pinion/pulley dimensions, overhang, speed profile and position-error budget. Confirm shaft support, permissible bearing loads and coupling stiffness with the gearbox and motor drawings.

PV / handling equipment

Duty, environment and service access

Provide shift hours, ambient conditions, dust, cleaning exposure and shutdown frequency. Agree lubrication/installation orientation, replacement access, spare adapter parts and the records required at acceptance.

Pinghu company identity and engineering context.

The official contact page identifies Zhejiang Beitto Transmission Technology at 508 Xingping First Road. Zhejiang's government-hosted Science and Technology Brain lists a high-precision planetary-gear-reducer R&D centre supported by this company in Pinghu, with Building 5 at the same street address. This supports the organisation and research-location context; it is not a frame's performance certificate.

BEITTO's technology page describes small-module precision gear manufacture, surface wear resistance and backlash control. Its catalogues describe helical gears, bearings, adapter bushings and grease lubrication. Ask how the selected order is controlled: gear material/process, dimensional inspection, assembly identification and measured backlash under the agreed procedure.

The site also presents harmonic reducers and other planetary families. For a different architecture, request its own load and interface documents rather than extending the AHB/AHL ratings to it.

Request a frame selection with an agreed code.

A motor drawing and duty cycle make the proposal more useful than a generic “servo gearbox” enquiry.

Prepare sourcing request

Machine, quantity, axis layout and existing-drive details.
Ratio, frame, stage count and agreed precision code.
Continuous torque, repeated peaks and emergency stops.
Motor model and flange/shaft dimension sheet.
Output connection, radial/axial forces and load positions.
Motion cycle, input speed and positioning acceptance.
Mounting, environment, lubrication and service access.
Drawing revision, traceable inspection and supplying entity.
