Overview

The 9350 is the heaviest servo in the range: 390 kg·cm at 30 V, 690 g, in a 68 × 35 × 120 mm body machined from 7075 aluminium. Everything structural is 7075 including the output horn, which is a step up from the 6061-class cases used lower in the range.

Six ball bearings support a steel geartrain on a 25T-φ11.8 mm spline. The case has four M6 through-holes on a 68 mm spacing and a 8 mm thick mounting flange — the drawing in Downloads gives the full pattern, because this is a part you design a bracket around, not a part you bolt to a standard tray.

This page covers the CAN build: the same mechanics on a CAN bus, with arbitration and error checking handled in hardware. The version to pick when the machine already speaks CAN and a dropped frame must not become a wrong angle.

Performance at each supply voltage

Supply No-load speed Peak stall torque Idle current Stall current
24 V 0.280 s/60° (214 °/s) 320 kg·cm (31.39 N·m / 4444 oz·in) 200 mA 5 A
28 V 0.200 s/60° (300 °/s) 360 kg·cm (35.32 N·m / 4999 oz·in) 300 mA 6.5 A
30 V 0.160 s/60° (375 °/s) 390 kg·cm (38.26 N·m / 5416 oz·in) 400 mA 7 A
Specifications scale with supply voltage. When comparing against another servo, compare at the same rail — 390 kg·cm at 30 V and 320 kg·cm at 24 V are not the same machine.

How to size it

At 390 kg·cm the reaction torque on the mounting bracket is the real design constraint. Four M6 bolts on a 68 mm spacing carry it, but the bracket has to be stiff — a flexing plate will show up as lost travel at the output, not as a servo fault.

The 390 kg·cm figure needs 30 V. On 24 V it is 320 kg·cm at 0.28 s/60°, and stall current is only 5 A. If your supply sags under load, size the linkage at the sagged voltage, not at the label.

FAQ

What is the difference between the 9200 and the 9350?

Torque and size: the 9350 is 390 kg·cm in a 68 × 35 × 120 mm, 690 g 7075 case; the 9200 is 250 kg·cm in a 64 × 33 × 88.5 mm, 405 g case. Both run 24–30 V.

Is the cable included?

No. Both models end in a socket, and the mating cable is a separate item so you can order the length and connector the machine needs.

What bitrate and message set does it use?

Not printed on the inspection sheet. Ask for the CAN message set, bitrate options and node ID range before integration; they are supplied on request.

Why CAN instead of RS-485?

Arbitration and error detection are in hardware, so a corrupted frame is discarded rather than acted on, and several nodes can share the bus without a master polling loop.
