About the Airtac SE50 Standard Cylinder SE50AX240S
The AirTAC SE50AX240S 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 50 mm bore, a 240 mm stroke, and a SUS420J2 stainless steel rod, making it highly suitable for corrosive or washdown environments where standard carbon steel would fail. The square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting contamination.
Equipped with a built-in position magnet (-S), this unit directly supports AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. Field-adjustable pneumatic cushioning at both ends allows technicians to tune the end-of-stroke deceleration via a set screw, softening hard impacts when cycling at speeds up to 800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50AX240S Is Used
Bottle Rinser Gating
Utilizes the SUS420J2 stainless rod and 982 N push force to actuate washdown spray gates on beverage filling lines, resisting moisture while cycling 240 mm to clear container paths.
Case Flap Folding
Drives a 240 mm stroke arm to fold heavy corrugated carton flaps prior to sealing, relying on the adjustable end cushions to prevent marking the packaging at high speeds.
Pallet Divert Arm
Extends to push routed pallets onto secondary transfer lines, using the integrated magnet and DMSE sensor to confirm full extension before the conveyor advances.
Is the Airtac SE50 Standard Cylinder SE50AX240S the Right Cylinder?
When sizing this 50 mm bore, step down to a 40 mm cylinder for 628 N push at 0.5 MPa, or step up to a 63 mm unit for 1559 N if your payload demands greater thrust. Because the 240 mm stroke generates leveraged side loads on the M16x1.5 rod thread, implementing an external guide rail prevents rod-bearing bending and premature seal wear. The PT1/4 porting and standardized ISO 15552 mounting dimensions ensure this cylinder serves as a drop-in replacement for any equivalent profile cylinder footprint. Note that the adjustable air cushion only decelerates the piston near stroke end; it cannot hold a load if air pressure is lost, so a BSE rod lock is required for fail-safe holding.
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 SE50AX240S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N push and 825 N pull force. At 0.7 MPa, the push force increases to 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes. The SE50AX240S is dimensionally interchangeable per ISO 15552 standards, meaning it shares identical mounting and port dimensions. You can use it as a drop-in replacement for other ISO 15552 profile cylinders without altering the machine footprint.
