Notes on this data
Metric as printed; speed converted m/s to mm/s (1.66 m/s = 1,660 mm/s). Max acceleration 10 m/s2. Repeatability +/-0.01 mm. Strokes down to 50 mm possible on request. Backlash not stated.

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 | PC Series precision linear actuators | RSA-ST (standard thrust) |
|---|---|---|
| Force | 6,000 N | 17,917 N meets or exceeds |
| Stroke | 1,200 mm | 1,524 mm meets or exceeds |
| Speed | 1,660 mm/s | 3,124 mm/s meets or exceeds |
Heavy-duty version of the RSA rod actuator with roller-screw options, matched angular-contact bearings and larger motor mounts, reaching 58 kN on size 64.
| Published maximum | PC Series precision linear actuators | RSA-HT (high thrust) |
|---|---|---|
| Force | 6,000 N | 58,000 N meets or exceeds |
| Stroke | 1,200 mm | 1,524 mm meets or exceeds |
| Speed | 1,660 mm/s | 3,124 mm/s meets or exceeds |
RSA-based rod actuator with integral hardened guide rods, bearings and a tooling plate, so it can carry side and offset loads without external guidance.
| Published maximum | PC Series precision linear actuators | GSA Guided Screw Actuator |
|---|---|---|
| Force | 6,000 N | 4,226 N |
| Stroke | 1,200 mm | 914 mm |
| Speed | 1,660 mm/s | 3,124 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.
