Notes on this data
Metric values as printed by Curtiss-Wright alongside imperial (no conversion needed). Peak force taken from product page/overview quick data; the catalog itself says not to exceed 2x continuous force rather than tabulating peak N. Continuous ratings at 25 C ambient. Extended ambient -30 to 65 C listed (consult factory); storage -80 to 85 C. Backlash 0.102 mm (0.004 in); lead error 25 um/300 mm; no repeatability figure published. Product page links a newer catalog revision (2026 GTX Product Catalog.8-26.pdf) than the one read (.5-26).

Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with an Exlar 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.
Rod actuator with a built-in servo motor driving a ball or roller screw, in four sizes up to 30.6 kN, offered in white food-grade and black heavy-duty finishes.
| Published maximum | GTX Series | IMA Integrated Motor Actuator |
|---|---|---|
| Force | 30,784 N | 30,600 N |
| Stroke | 450 mm | 457 mm meets or exceeds |
| Speed | 1,270 mm/s | 1,334 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 | GTX Series | RSA-HT (high thrust) |
|---|---|---|
| Force | 30,784 N | 58,000 N meets or exceeds |
| Stroke | 450 mm | 1,524 mm meets or exceeds |
| Speed | 1,270 mm/s | 3,124 mm/s meets or exceeds |
Steel-belt driven linear module with integral guide rail, intended as a long-stroke, high-speed replacement for pneumatic cylinders.
| Published maximum | GTX Series | LB Belt-Drive Linear Actuator |
|---|---|---|
| Force | 30,784 N | — |
| Stroke | 450 mm | 3,050 mm meets or exceeds |
| Speed | 1,270 mm/s | 2,000 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.
