When this is the right choice
- 210 g lighter than CRA-RI50-70-PRO for the same 6.6 N·m at 51:1 — a straight mass saving on a distal axis.
- 23 N·m start–stop is 3.5× the rated figure, which is a healthy shock margin for a wrist.
- 24–80 V, same as the rest of the line.
When it is the wrong choice
- One ratio only. If the speed turns out wrong there is no 101:1 to fall back on and the mechanical design changes.
- PRO-S parts are less documented than PRO — body length and bore are not published for this frame, so confirm on the drawing.
- No brake or torque sensor, and the numbers are still being re-verified against the current Ti5 catalogue.
Alternatives at a similar level
- Ti5 CRA-RI50-70-PRO — Same torque, 660 g, three ratios
- Ti5 RI60-70-PRO-S — 19.8 N·m at 730 g — one frame up
- DAMIAO DM-JH11 — 3.2–4.8 N·m harmonic at 345 g

RI50-60-PRO-S FAQ
PRO-S or PRO at Φ50?
PRO-S if you know you want 51:1 and want the 210 g. PRO if there is any chance the speed target moves, because the ratio is fixed on the S part.
What does the S stand for?
Short body, single ratio. Same gear and motor family, less housing and no ratio option.
How long does it take to ship?
Confirmed per order at quotation, with the specification re-check on this series.
