Shanghai Bangrun Precision Machinery
上海邦润精密机械有限公司
A Shanghai supplier describing robot tool changers and quick-change workholding devices. Match both coupling halves and verify the legal contracting entity before comparing a proposal.
01 / Company
What this company supplies
A range built around changing tools and setups
The company website describes development, manufacture and sales of robot and manipulator tool changers, line-change devices, gripper-finger quick changes, pre-locking and zero-point positioning products, floating supports and locating or clamping devices. It also describes hydraulic and electrically controlled permanent-magnet mold-change systems for injection molding, stamping and die-casting equipment. This is a component and changeover range, not a complete robot-arm catalog. [B1]
Keep brand and contracting identity distinct
The website displays 上海邦润精密机械有限公司 and 上海帮快智能设备有限公司 alongside English names and BRQC branding. Shared presentation does not prove a legal ownership relationship or establish which entity will quote, invoice or warrant a purchase. The page’s 2009 history statement covers a combined company description, so this directory does not assign it as either entity’s verified incorporation date. [B1]
02 / Products
A range with distinct purchasing tasks
Robot and end-effector quick change
Robot tool changers and gripper-finger quick-change devices address different interfaces. Identify robot-side, tool-side and finger-side parts separately, together with their mounting drawings and sensing or utility options. [B1]
Workholding and mold change
The website also describes positioning, clamping, support and mold-change devices. These are adjacent product families; they do not inherit the RA08 or RA10 load ratings, pneumatic conditions or connectors. [B1]
Published in this directory
RA08 and RA10: compare the complete assembly [B2]
| Item | Published statement | Detail to keep with it |
|---|---|---|
| BRQC-RA08 | 5 kg stated rating | Robot-side mass 0.18 kg; tool-side mass 0.15 kg. |
| BRQC-RA10 | 10 kg stated rating | Robot-side mass 0.475 kg; tool-side mass 0.235 kg. |
| Shared published conditions | 0.40–0.60 MPa; six air circuits | D-SUB electrical connection is optional. Model-specific moments and air-loss behavior need documentation. |
A mass rating does not resolve tool center of gravity, inertia or bending moment. The host robot must also carry the changer assembly and adapters. Do not assume coupling halves from different models are interchangeable.
03 / Technical scope
A coupling is a system of matched interfaces
Mechanical pairing
A robot-side unit and its tool-side mate must be identified as a compatible pair. Obtain the flange, bolt pattern, stack height and mating drawings. The published RA08 and RA10 records are distinct products; dimensional compatibility and interchangeability are not established here. [B2]
Utilities and optional connections
The reviewed records state six air circuits and describe D-SUB electrical connection as an option. Determine the required air and signal paths, sensing and accessories in the quotation. An optional connector should not silently become part of the base configuration. [B2]
Operating and exception behavior
Ask for the coupling and uncoupling sequence, confirmation signals and the behavior on air loss. Load moments, permitted orientation and retention under faults are missing from the published records. The directory does not validate the locking mechanism or its safety performance. [B2]
04 / Quality
Certifications and quality
No unverified certificate badge
The published directory information establishes catalog statements, not independent material inspection, endurance testing or mechanism validation. No issuer-verified certificate or factory audit is attached to this profile. [B2]
Documents for a usable comparison
Request the exact paired part numbers, drawings, permitted loading conditions, pneumatic specification and operating instructions. Record the legal quote and warranty entity separately from brand names. Those documents address the actual gaps more directly than a general supplier-quality claim. [B1] [B2]
Before ordering, ask the company to send the certificates and test reports that apply to your configuration. How these profiles are compiled.
05 / Project fit
Where to start the technical discussion
Typical projects matched to the supply scope above, with the first questions to settle for each.
Several tools on one robot
Provide the mass and center of gravity of each complete tool, motion conditions, mounting and utilities. Evaluate the largest relevant moment and a documented tool-change sequence rather than choosing only by the nominal kilogram rating. For one robot using several tools, prepare a separate load and utility schedule for every complete tool. The heaviest tool may not create the largest moment; the offset and robot motion must be considered with the model-specific permitted loading conditions. [B2]
Frequent fixture or product changeover
For line or workholding changes, state the positioning and clamping task separately. Ask which quick-change family is proposed and what inspection or repeatability evidence supports it; a robot-tool-changer record does not establish those adjacent parameters. For frequent fixture changes, define whether the request is robot tool exchange or workholding/line positioning. The company lists adjacent quick-change families, but the RA08/RA10 records do not establish clamping force or positioning performance for those other families. [B1]
Compare proposals on the same basis
| Decision | Documents to request | Check before ordering |
|---|---|---|
| Legal and quotation identity | The company name on the quote, invoice, warranty and bank documentation for the intended purchase. | Shared website branding proves ownership or legal equivalence. |
| Matched components | Exact robot-side and tool-side part numbers and mounting drawings. | RA08 and RA10 components are interchangeable. |
| Permitted loading | Tool assembly geometry and model-specific mass and moment conditions. | A stated 5 or 10 kg rating resolves every load case. |
| Service and options | Air circuits, electrical connectors, sensing and the documented coupling sequence in the quote. | Optional hardware is included because it appears in a range description. |
Turn the supply scope into a project handover
The documents and checks to agree with this company at each stage of delivery.
Resolve the paired interfaces
Name both changer halves, robot and tool flange patterns, adapter drawings and docking orientation. Confirm whether a replacement half can be paired with the existing unit; adjacent models and similar pictures do not establish interchangeability.
Create the full load schedule
Include both coupling halves, adapters, tool, services and workpiece, then record centre of gravity and operating acceleration. Ask for model-specific moment and loading conditions instead of treating the published kilogram figure as every permissible loading case.
Allocate circuits and feedback
Assign each pneumatic circuit and optional electrical connection to a function. Ask for port/flow ratings, wiring and lock feedback, and identify which accessories are included. A six-circuit description is not a complete utility specification.
Document the docking and fault protocol
Agree checks before unlocking, coupling and robot withdrawal. Request behavior under lost air, missing lock confirmation and interrupted docking, and validate recovery with the responsible integrator. Record exact part numbers in the acceptance report.

Common buyer questions
Can RA10 replace RA08 because it has a larger rating?
Not from the rating alone. Compare flange drawings, coupling halves, docking alignment, installed mass, moments, circuits and feedback. A larger nominal load does not establish a drop-in replacement.
What legal identity should be used for an order?
Ask for the quotation, invoice and warranty legal holder and match it to the company documents. Bangrun/Bangkuai branding and a combined history statement are not independent proof that all names are interchangeable contracting entities.
Are Bangrun and Bangkuai the same legal entity?
The profile does not establish that relationship. Verify the legal contracting name and supporting documents directly.
Does this profile validate the locking mechanism?
No. Model-specific operating and exception behaviour require supplier documentation and application review.
