About the Airtac SE50 Standard Cylinder SE50X75SFTC
The AirTAC SE50X75SFTC is a double-acting, single-rod ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Because it features a square extruded aluminum barrel without external tie rods, it mounts flush against machine frames and completely avoids the corrosion traps typical of exposed rod hardware. This FTC-mounted unit includes a built-in magnet for position detection.
Field-adjustable pneumatic cushioning at both ends allows you to tune the end-of-stroke deceleration via a simple screw, softening hard impacts when cycling at speeds up to 800 mm/s. The integrated -S magnet directly interfaces with AirTAC CMSE reed and DMSE electronic sensors, dropping cleanly into the three-sided sensor grooves for reliable switching without bulky external brackets.

Where the Airtac SE50 Standard Cylinder SE50X75SFTC Is Used
Carton Erector Jaws
Drives the folding jaws on automated carton erectors, utilizing the 982 N push force at 0.5 MPa to cleanly crease and seal heavy corrugated board.
Pallet Diverter Gate
Actuates routing gates on conveyor lines, where the 75 mm stroke rapidly redirects pallets without overshooting due to tuned adjustable air cushions.
Lab Sample Ejector
Ejects processed test tubes from centrifuge carousels, relying on the flush extruded barrel and CMSE/DMSE magnet sensors for compact, tracked ejection.
Is the Airtac SE50 Standard Cylinder SE50X75SFTC the Right Cylinder?
If 982 N of push at 0.5 MPa is too much for your fixture, stepping down to the 40 mm bore yields 628 N. Conversely, if you need more thrust, the 63 mm bore provides 1559 N at the same pressure. Remember that a plain SE cylinder cannot hold a load if air is lost or the valve centers; the piston will drift, so use a BSE rod lock for fail-safe holding. For this 75 mm stroke, side-load stress on the M16x1.5 rod thread is minimal, but always verify guide alignment.
As a true ISO 15552 profile cylinder, this 50 mm bore unit with a PT1/4 port and FTC mounting is dimensionally interchangeable with any other ISO 15552 cylinder, making it a fast drop-in retrofit for existing ISO 15552 footprints without needing custom machined plates.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SE50 Standard Cylinder SE50X75SFTC FAQ
At 0.5 MPa, it provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force reaches 1374 N. The maximum allowable push force is 200 kgf at 1.0 MPa.
Yes. The SE50X75SFTC is dimensionally interchangeable per ISO 15552 standards. Its standardized mounting interface and PT1/4 port allow it to drop in as a direct replacement for other ISO 15552 profile cylinders without altering your existing mounting hardware.
