QFB210-16 QFB industrial arm
A source-based selection review of QFB210-16: 16 kg effective load and 2,100 mm working radius, with tooling, integration and safety questions kept separate from the catalog figures.
Manufacturer data with selection guidance for buyers.
Manufacturer data
Published specifications
QFB210-16 is a six-degree-of-freedom QFB arm listed by Chege Robotics. The official model page states an effective load of 16 kg, working radius of 2,100 mm and repeatability of ±0.05 mm. These are supplier-published figures, without an independent equipment trial. Confirm the complete tooling load, installation envelope and exact safety documentation before using the model in a production cell.

What should drive this model decision?
The QFB210-16 occupies the middle position in this published range: 2,100 mm working radius, 16 kg effective load and approximately 45 kg body mass. That combination is worth evaluating when the 1,400 mm model cannot reach both stations, without automatically choosing the longest arm. The listed six-dimensional force range is a measurement claim rather than a permitted human-contact limit. For a finishing or contact task, agree on tool orientation, contact force, load case and detection behaviour before deciding whether the force data meets the process requirement.

Read the specification with its conditions
| Published item / decision | How to use it | Limit to confirm |
|---|---|---|
| Degrees of freedom | 6 | Quoted by the supplier; obtain joint travel and speed tables. |
| Effective load | 16 kg | Tool, adapter and workpiece must be assessed together. |
| Working radius | 2,100 mm | A scalar maximum, not a guaranteed accessible work volume. |
| Repeatability | ±0.05 mm | Does not establish absolute accuracy or loaded path accuracy. |
| Body mass | Approximately 45 kg | Installation reaction loads still need a drawing. |
| Supply / typical power | 220 V / approximately 1000 W | Ordinary conditions; supply sizing and maximum demand are unknown. |
| Controller / teaching | Integrated / phone, tablet, API and JSON | Exact versions, offline operation and access control need confirmation. |
| Communications | WiFi, Ethernet port, Bluetooth and RS485 | Named interfaces do not prove protocol compatibility with your PLC. |
| Six-dimensional force range | 200 N / 7 Nm | Not a human-contact safety limit; ask for the measurement definition. |

Resolve the safety and protection claims
The model page labels the arm protection as C-T4. This notation has not been established here as an ingress protection rating, explosion-protection certification or a complete safety approval. Obtain the applicable certificate, issuing body, model scope and installation conditions before specifying use in a spray booth or hazardous atmosphere.
The QFB family is described as collaborative by its supplier. That description does not make a cell safe without guarding. Review the tool, sharp edges, workpiece, reachable trapping points, permitted operating mode and risk assessment for the complete installation.
The supplier quotes less than 0.1% FS for six-dimensional force accuracy. Full-scale definition, calibration conditions and system accuracy have not been independently verified.
Record scope: [S1]
Agree on a measurable acceptance record
- Freeze the exact model, controller firmware, accessory list and stated load case in the quotation.
- Run the agreed loaded trajectory with representative parts and tooling. Record cycle time and stopping / recovery behaviour under the chosen operating mode.
- Separate repeatability measurements from absolute position and process-quality measurements. Agree on fixtures, measurement method and acceptance limits before the trial.
- Record backup, restore, maintenance and operator training deliverables. Request safety documents and support responsibilities for the country of installation.

Questions the model page does not settle
Is the listed load the usable workpiece mass?
The model page states 16 kg effective load, but it does not provide the wrist moment or inertia envelope. Include all attached tooling and ask for a reviewed load case.
Can this arm be used for explosive-atmosphere spraying?
The C-T4 text alone is insufficient to establish certification or permitted conditions. No such certification is asserted in this directory.
Does the site verify product performance?
No. This page distinguishes supplier catalog facts from platform purchasing guidance. There is no claimed factory visit, independent trial, measured production saving or expert sign-off.
