About the Airtac SE50 Standard Cylinder SE50X800FTC
The AirTAC SE50X800FTC is a double-acting single-rod profile cylinder built to ISO 15552 dimensions, featuring an 800 mm stroke and an FTC front trunnion mount. It delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for mid-range linear actuation. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This SKU is supplied without a position-sensing magnet, so it operates purely as a blind actuator unless external limit switches are fitted. Field-adjustable pneumatic cushioning at both ends allows technicians to tune the end-of-stroke deceleration via a set screw, softening the impact of the 20 mm hard-chrome rod as it traverses the lengthy 800 mm span at speeds up to 800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50X800FTC Is Used
Pallet Transfer Pusher
Uses the 982 N push force at 0.5 MPa to index heavy wooden pallets along a roller conveyor over the full 800 mm stroke, relying on the FTC mount to handle the pivot reaction forces.
Corrugated Box Flap Folder
Actuates a folding arm mechanism over an 800 mm travel to close large carton flaps, utilizing the adjustable end cushions to prevent tearing the cardboard at high cycling speeds.
Press Brake Material Stop
Positions a metal sheet back-gauge accurately in a press brake, where the ISO 15552 footprint allows easy retrofitting and the 825 N pull force safely retracts the stop arm.
Is the Airtac SE50 Standard Cylinder SE50X800FTC the Right Cylinder?
When sizing this 50 mm bore actuator, note that stepping down to a 40 mm bore reduces the 0.5 MPa push force to 628 N, while stepping up to a 63 mm bore increases it to 1559 N. This model uses a PT1/4 port and an FTC front trunnion accessory, providing a fixed pivot point at the head end. Because this cylinder lacks a built-in magnet, it cannot host AirTAC CMSE or DMSE sensors for internal position detection.
With an 800 mm stroke, the unsupported rod mass introduces significant side-load leverage at the front bearing. Even with the robust 20 mm rod and M16x1.5 thread, you must use an external guide mechanism to prevent rod-bearing bending and premature seal wear. Furthermore, the adjustable air cushion only decelerates the piston near the stroke ends; it cannot hold a load if air pressure drops. If your application requires dead-load holding, pair this cylinder with 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 SE50X800FTC FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force is 1374 N, and the maximum push capacity is 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE50X800FTC is dimensionally interchangeable with other ISO 15552 profile cylinders. It shares the same mounting footprint, PT1/4 ports, and 20 mm rod thread, allowing for a drop-in retrofit using your existing FTC mounting hardware.
