Buying industrial robotics cobots involves more than choosing the lower listed price. These two robot arms are separated by USD 2,249.99 and have materially different configurations, conditions, and project roles. The useful decision is whether the higher-priced Staubli's named configuration matters more than the Denso's lower entry figure.
Quick verdict
The Staubli Faverges TX90 ESD 6-Axis Industrial Robot Arm 100cm Reach 6 kg Payload is the direction for a project with a precise configuration requirement. The 2018 Denso HMS-40704M-W 4 Axis Industrial Robot Arm has the lower listed price, but it represents a more narrowly defined project choice. This is not an interchangeable pair: the Staubli centers on its declared reach, payload, and axis count, while the Denso is classified for parts or not working.
Compact comparison
| Decision point | Staubli TX90 | 2018 Denso HMS-40704M-W |
|---|---|---|
| Listed price | USD 2,999.99 | USD 750.00 |
| Condition | Used | For parts or not working |
| Key concern | Oil leakage at Joint 1, Joint 2, or both | No controls accompany the arm |
| Arm configuration | Six-axis | Four-axis |
Where each robot arm wins
Staubli TX90: when reach, payload, and axes drive the choice
The Staubli is the more appropriate pick when the project is being selected around the named 100cm reach, 6kg payload, and six-axis format. Those are concrete selection points for shoppers who already know that this configuration is required. Its used condition does not erase those specifications, but the oil-leak issue should be considered part of the project scope rather than a minor cosmetic detail.
Denso HMS-40704M-W: for an intentional parts-focused project
The Denso makes sense when the target is specifically a 2018 four-axis Denso HMS-40704M-W for a parts-oriented project. Its USD 750.00 price places it far below the Staubli's ask, but the for-parts-or-not-working condition and lack of controls define the role it can play. It is best suited to a buyer deliberately pursuing that kind of project rather than someone choosing solely by price.
Product notes
Staubli Faverges TX90 ESD 6-Axis Industrial Robot Arm 100cm Reach 6 kg Payload
Choose the Staubli when the TX90 bmn model designation is a direct fit and the six-axis, 100cm-reach, 6kg-payload specification is central to the project. It is the more configuration-specific arm in this comparison, giving shoppers clear measurements and payload language to work from. The limitation is substantial: either Joint 1, Joint 2, or both are leaking oil, with staining on the side of the arm. Scuffs, scratches, and wear on the custom end effector are also noted. This used arm is best approached where those mechanical and cosmetic issues are already accommodated in the project plan.
2018 Denso HMS-40704M-W 4 Axis Industrial Robot Arm
The Denso is worth considering when a project specifically calls for the HMS-40704M-W and its stated 2018 manufacture date is useful for identifying the arm. Its four-axis format gives it a distinct role from the Staubli rather than making it a direct replacement. The central limitation is clear: it is classified for parts or not working, and no controls accompany the arm. That makes the Denso a focused choice for a buyer who intends to work within those constraints. Its lower listed price is meaningful, but the intended project role matters more than the headline figure alone.
Final choice by use case
Choose the Staubli TX90 when its named configuration is important enough to justify the higher listed price and its condition issues fit the project scope. Choose the Denso HMS-40704M-W only when a parts/not-working arm without controls is an intentional fit. With USD 2,249.99 between the two listed prices, the decision should rest on the arm's role in the project, not on treating one as a simple substitute for the other.
