About the Airtac SE50 Standard Cylinder SE50X75FTC
The AirTAC SE50X75FTC is a double-acting single-rod ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. It features a square extruded aluminum barrel without external tie rods, yielding a compact footprint that resists corrosion and mounts flush against machine frames.
This 50 mm bore unit includes an FTC integrated mounting interface and a field-adjustable pneumatic cushion at both ends to soften end-stop impact. This specific SKU lacks the built-in magnet, meaning it is not wired for CMSE or DMSE position sensing without modification.

Where the Airtac SE50 Standard Cylinder SE50X75FTC Is Used
CNC Lathe Chuck Actuation
Provides 982 N of extend force to pivot an FTC-mounted lever arm, reliably opening and closing a heavy lathe chuck door during automated bar feeding cycles.
Carton Flap Folding
Uses the 75 mm stroke to rapidly fold corrugated cardboard flaps on a continuous packaging line, relying on the adjustable end cushions to prevent hard mechanical slams at high speeds.
Stamping Press Ejection
Kicks stamped metal blanks out of a die bed using 825 N of retract force, taking advantage of the tie-rod-free extruded profile to fit within tight press sub-plates.
Is the Airtac SE50 Standard Cylinder SE50X75FTC the Right Cylinder?
Delivering 982 N push at 0.5 MPa, this 50 mm bore fits mid-range actuation. If your application requires less force, the 40 mm bore offers 628 N; if you need more power, stepping up to the 63 mm bore provides 1559 N. Because the FTC mount handles pivotal rotation, ensure the pin clearance matches the ISO 15552 interface.
Remember that a standard SE cylinder does not hold loads when air pressure is lost—the piston will drift. For position holding without live pressure, consider the BSE rod lock variant. This 75 mm stroke is short enough to avoid rod-bearing bending, but longer unsupported strokes require an external guide.
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 SE50X75FTC FAQ
The 50 mm bore generates 982 N push and 825 N pull at 0.5 MPa. At 0.7 MPa, the push force is 1374 N. The maximum push force is 200 kgf at 1.0 MPa.
Yes. The SE50X75FTC is dimensionally interchangeable per ISO 15552 standards, meaning it serves as a drop-in replacement for other ISO 15552 profile cylinders using the same FTC mounting interface and PT1/4 port.
