Orbital motor — catalogue item 001
A named orbital-motor website entry with a catalogue photograph. The identifier 001 does not establish displacement or an installation-ready order code.
The catalogue label is the starting point
Choose the real motor variant before choosing an operating value.
- Supplier page title
- 摆线液压马达001 — orbital hydraulic motor 001
- Public evidence
- Catalogue photograph and item classification
- Order identity still needed
- Complete series/size/shaft/mounting/port code and drawing revision
The current official detail page has “overview” and “dimensions” tabs. Both were checked; no readable model-specific parameter or dimension sheet was retrieved. [1] The reference does not mean 1 cm³/rev, and the picture cannot determine shaft/flange variants or the motor’s allowable load.
Do not order solely as “001”
Ask the supplier to return the production part code corresponding to this website entry, with its current drawing and performance sheet. Keep that returned code on the quotation and subsequent approval.
HIM and MS literature are not this item’s data
Hewell’s electronic catalogue contains named HIM radial-piston motor tables and coded shaft/distributor/mounting options. Its separate MS sample addresses another named series. [2] [3] Their availability does not identify the orbital entry as either family.
| Document returned | What must match item 001 | Do not infer |
|---|---|---|
| Full order-code sheet | Supplier’s explicit cross-reference to the website entry | Size from the number 001 |
| Outline drawing | Actual shaft, flange/pilot, bolt pattern, ports and envelope | Dimensions from a similar photograph |
| Performance curves | Exact selected size/code and stated test/duty conditions | Torque/pressure values from HIM or MS tables |
| Installation instructions | Drain/return, fluid, seals, cleanliness and delivered configuration | Another motor family’s commissioning procedure |
A replacement needs an interface comparison
Send the existing installation
Nameplate and full designation; shaft/coupling, mounting and port drawings; circuit; required torque/speed and start-stop duty. State which connections cannot change.
Ask for the proposed differences
Supplier-marked deviations in dimensions, rotation, ports/drain and operating envelope. Identify any necessary coupling, circuit or mounting modification before acceptance.
Specify driven radial/axial loads and where they act, rather than assuming the photograph permits a direct pulley or wheel load. Establish whether the motor is supplied alone or with a reducer, brake and control block. Other-brand catalogue headings do not authenticate an authorized or drop-in replacement.
Three checkpoints before approving supply
- Identify. Obtain the full part code and signed-off interface drawing. If this cannot be resolved, the item remains an enquiry reference.
- Review duty. Compare the selected unit’s actual speed/torque point, pressure/flow, limits and thermal conditions with the application. Keep rated, peak and intermittent labels as the exact sheet defines them.
- Agree acceptance. Request dimensional and measured performance records with conditions, lot/unit identity and acceptance criteria, then define the assembled-machine trial.
ISO 4409’s abstract describes steady-state performance/efficiency methods and presentation for rotating hydraulic components. [4] It can guide the requested report; it is not a factory test result, endurance claim or safety approval for the complete drive.
Why are price, torque and displacement not filled in?
The source does not establish the full variant or a real offer. A guessed specification would make a replacement comparison less reliable. Request the selected code’s data and terms together.
Ask the supplier to identify item 001
