About the Airtac SE50 Standard Cylinder SE50X65STC
The AirTAC SE50X65STC is a double-acting, single-rod profile cylinder operating on filtered air. Built to the ISO 15552 standard, its extruded aluminum barrel lacks external tie rods, yielding a smooth, corrosion-resistant body that mounts flush against machine frames. Delivering 982 N of push force at 0.5 MPa, it is engineered for dynamic actuation tasks requiring 65 mm of travel.
This configuration includes a built-in magnet for CMSE reed and DMSE electronic position sensing. The TC center trunnion mount provides a pivot point for articulated mechanisms, while the field-adjustable air cushioning at both ends allows you to tune end-of-stroke deceleration, replacing harsh impacts with controlled stops.

Where the Airtac SE50 Standard Cylinder SE50X65STC Is Used
CNC Fixture Clamping
Provides 982 N of push force at 0.5 MPa to secure aluminum castings against a machining bed during milling operations.
Carton Flap Folding
Executes a 65 mm stroke to tuck corrugated cardboard flaps prior to top-sealing on a continuous packaging conveyor.
Diverter Gate Actuation
Leverages the TC trunnion mount to pivot a sorting gate smoothly, redirecting packages on a high-speed logistics belt.
Is the Airtac SE50 Standard Cylinder SE50X65STC the Right Cylinder?
This 50 mm bore generates 982 N push at 0.5 MPa. If your application demands less force, stepping down to the 40 mm bore yields 628 N push, whereas moving up to the 63 mm bore provides 1559 N push for heavier payloads. Because the stroke is 65 mm, side-load stress on the rod bearing is minimal, though an external guide remains best practice for rigid loads.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other standard profile cylinders. To match this exact unit, specify bore 50, stroke 65, PT1/4 port, TC trunnion mounting, and the -S magnet option. Note that the adjustable air cushion only decelerates the piston near stroke end; it does not hold a load. If your process loses air pressure and requires position holding, use a BSE rod lock or an external pilot-operated check valve.
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 SE50X65STC FAQ
At 0.5 MPa, the SE50X65STC delivers 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N. The maximum push force is 200 kgf when operating at the 1.0 MPa pressure limit.
Yes. The SE50X65STC is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact same mounting footprint and body dimensions as other standard profile cylinders. It functions as a drop-in replacement, provided you match the TC trunnion mount, PT1/4 port, and 65 mm stroke.
