Once a project moves from “can we collaborate?” to “can we hold takt under load?”, peak specs start to matter. r-Ultra is for lines that already know they need heavy capacity yet still want teach-friendly deployment and a compact cell.
Thirty kilograms rated (35 kg max), 1402 mm reach, and ±0.1 mm repeatability serve real pallet envelopes, machine door clearances, and stack heights—not brochure sorting. For integrators, one less hard guard layer and one less floor rework often decides schedule more than a torque curve.
The r-Ultra page organizes 3D story, blueprints, and applications in the same assessment language: confirm payload and reach first, then I/O and fieldbus fit, then trajectory and takt tuning. We do not sell a universal arm at bid stage—we explain the default spare and process template for heavy collaborative work.
If you are choosing between r-Core and r-Ultra, the decisive question is usually not the largest number—it is whether this heavy cell will still be the predictable, maintainable tier on your line five years out.
