Sealed modular actuator with reduction, sensing, controller and optical-Ethernet daisy chain
Motion & Actuation · Integrated rotary joint actuator
R8-9+
A field-oriented modular actuator whose official datasheet separates continuous torque from peak torque and publishes environmental and sensing information.
11 known suppliers in this product family.
Motor, reduction, feedback and drive electronics sold as an integrated or near-integrated robot-joint product. The list is bounded to the current RCI manufacturer-directory universe and separates exact-model audited suppliers from confirmed product-line suppliers.

1 bounded physical-evidence record.
Publisher independence, identity precision and measurement scope vary by row. Results remain bounded by the disclosed specimen, setup, workload and metric; an inconclusive mapping is evidence associated with the catalog model, not verification of a manufacturer claim.

Known limits
What this record does not prove.
- The headline peak-torque duration is not stated in the summary table.
- Torque and speed maxima must not be treated as a simultaneous operating point.
