Rod actuator
Thomson Electrak XD
Thomson's highest-force 24/48 V DC rod actuator, using a ball screw and onboard monitoring electronics to reach 25 kN with a higher duty cycle than the HD.

Notes on this data
Metric as printed (page uses '11.000 N' style thousands separators). force_N_max is dynamic; static up to 32 kN. Max current 30 A at 24 V, 15 A at 48 V. End play 1.2 mm. Repeatability not published. XD not listed on the older training overview page.

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 XD | RSA-ST (standard thrust) |
|---|---|---|
| Force | 25,000 N | 17,917 N |
| Stroke | 1,200 mm | 1,524 mm meets or exceeds |
| Speed | 75 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 XD | SRB Linear Servo Actuator |
|---|---|---|
| Force | 25,000 N | 49,033 N meets or exceeds |
| Stroke | 1,200 mm | 1,000 mm |
| Speed | 75 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 XD | RSH Hygienic Rod Actuator |
|---|---|---|
| Force | 25,000 N | 35,330 N meets or exceeds |
| Stroke | 1,200 mm | 1,219 mm meets or exceeds |
| Speed | 75 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.
