About the Airtac SE50 Standard Cylinder SE50X70S
The AirTAC SE50X70S is a double-acting, single-rod ISO 15552 profile cylinder engineered for compact, high-cycle automation. With a 50 mm bore and 70 mm stroke, it generates 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa. The extruded aluminum barrel design omits external tie rods, yielding a smooth, corrosion-resistant body that mounts flush against machine frames while retaining structural rigidity.
Equipped with a built-in magnet (-S), this unit directly supports AirTAC CMSE reed and DMSE electronic position sensing. Field-adjustable pneumatic cushioning at both stroke ends allows technicians to tune deceleration via a set screw, softening hard mechanical stops during rapid 30-800 mm/s traverse speeds.

Where the Airtac SE50 Standard Cylinder SE50X70S Is Used
Carton Erector Flaps
Provides the 982 N push force required to cleanly fold and seal heavy corrugated carton flaps on high-speed packaging lines.
Pallet Diverting Gate
Uses the 70 mm stroke to rapidly extend a diverter arm, redirecting heavy pallets between conveyor belts at 30-800 mm/s.
CNC Tool Unlatching
Delivers precise linear actuation to release heavy interlock mechanisms on machining centers, benefiting from the smooth no-tie-rod profile.
Is the Airtac SE50 Standard Cylinder SE50X70S the Right Cylinder?
Generating 982 N of push at 0.5 MPa, this 50 mm bore sits neatly between the 40 mm option (628 N) and the 63 mm class (1559 N), allowing designers to scale force up or down without changing the ISO 15552 mounting footprint. The PT1/4 port and 70 mm stroke provide rapid positioning for mid-weight loads.
Because the adjustable air cushion only decelerates the piston near the end of travel, it cannot hold a vertical load if air pressure drops or the valve centers; for position holding without live pressure, specify a BSE rod lock variant. The integrated -S magnet pairs instantly with CMSE or DMSE switches for end-of-cycle confirmation.
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 SE50X70S FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, the push force is 1374 N. The maximum allowable push force is 200 kgf at 1.0 MPa.
Yes. The SE50X70S is dimensionally interchangeable per ISO 15552 standards, meaning it serves as a drop-in replacement for other ISO 15552 profile cylinders using the same 50 mm bore and PT1/4 port.
