Notes on this data
Metric as printed. force_N_max is dynamic load; max static load 18 kN all models. Strokes in 50 mm increments. End play 1.2 mm max; 500 h salt spray. Training overview lists only 12/24 Vdc and 'up to 16 kN' - product page adds 48 Vdc. Repeatability not published. Catalog PDFs on page require sign-in; not accessed.

Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a Thomson part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These 3 series from our supply network are the closest match on published figures.
General-purpose electric rod actuator in six sizes with solid, bronze or ball screws and inline or reverse-parallel motor mounting; a broad pneumatic/hydraulic replacement workhorse.
| Published maximum | Electrak HD | RSA-ST (standard thrust) |
|---|---|---|
| Force | 16,000 N | 17,917 N meets or exceeds |
| Stroke | 1,000 mm | 1,524 mm meets or exceeds |
| Speed | 71 mm/s | 3,124 mm/s meets or exceeds |
Ball-screw servo electric cylinder in seven frame sizes from 32 to 150, with inline or reverse-parallel motor mounting and optional force sensing, aimed at hydraulic and pneumatic replacement.
| Published maximum | Electrak HD | SRB Linear Servo Actuator |
|---|---|---|
| Force | 16,000 N | 49,033 N meets or exceeds |
| Stroke | 1,000 mm | 1,000 mm meets or exceeds |
| Speed | 71 mm/s | 1,250 mm/s meets or exceeds |
All-316 stainless electric rod actuator with IP69K washdown rating and ball or roller screws, designed to hygienic guidelines for higher-force food, beverage and pharma tasks. Replaces the ERD22/25/30 hygienic sizes.
| Published maximum | Electrak HD | RSH Hygienic Rod Actuator |
|---|---|---|
| Force | 16,000 N | 35,330 N meets or exceeds |

| Speed | 71 mm/s | 500 mm/s meets or exceeds |
Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
