Rod actuatorLegacy
Thomson Electrak 10
Older general-purpose DC rod actuator offered with acme or ball screw up to 6.8 kN; Thomson now files it under legacy products.
Thomson lists this series as legacy. We can help with spares for installed machines, a migration to the replacement, or an alternative.

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 10 | RSA-ST (standard thrust) |
|---|---|---|
| Force | 6,800 N | 17,917 N meets or exceeds |
| Stroke | 610 mm | 1,524 mm meets or exceeds |
| Speed | 61 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 10 | SRB Linear Servo Actuator |
|---|---|---|
| Force | 6,800 N | 49,033 N meets or exceeds |
| Stroke | 610 mm | 1,000 mm meets or exceeds |
| Speed | 61 mm/s | 1,250 mm/s meets or exceeds |
Economical stainless-tube electric rod actuator in sizes 10, 15 and 20, aimed at replacing pneumatic cylinders for gating, sorting and diverting; SS1/SS2 options give an all-stainless, IP69K washdown build.
| Published maximum | Electrak 10 | ERD (incl. ERD-SS1 / ERD-SS2 stainless… |
|---|---|---|
| Force | 6,800 N | 2,224 N |
| Stroke | 610 mm | 610 mm meets or exceeds |
| Speed | 61 mm/s | 1,016 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.
