About the Airtac SE50 Standard Cylinder SE50AX20S
The AirTAC SE50AX20S is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and a 20 mm stroke. It delivers 982 N of push force at 0.5 MPa and reaches a maximum of 200 kgf at 1.0 MPa. The extruded aluminum barrel lacks external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while exposing no vulnerable hardware to the working environment.
This specific configuration features a SUS420J2 stainless steel rod (code A) for corrosive or washdown duty, alongside a built-in magnet (code S) for position detection. The integrated magnet interfaces directly with AirTAC CMSE reed and DMSE electronic sensors fitted into the three-sided sensor grooves. Furthermore, the end caps house field-adjustable pneumatic cushioning, allowing technicians to tune end-of-stroke deceleration via a set screw rather than relying on a fixed rubber bumper.

Where the Airtac SE50 Standard Cylinder SE50AX20S Is Used
Flow Wrapper End-Seal Jaw
Drives the rotary or reciprocating jaw on a continuous flow wrapper, utilizing the 982 N push force and 20 mm stroke to cleanly crimp and sever packaging film at high cycle rates.
Laboratory Sample Dispenser
Actuates a precision metering valve for chemical dispensing, where the SUS420J2 stainless rod resists corrosive vapors and the short 20 mm stroke provides rapid, repeatable dosing.
PCB Router Clamping Arm
Secures printed circuit boards during routing operations, using the compact profile body to fit within dense electronics manufacturing cells while providing reliable holding force.
Is the Airtac SE50 Standard Cylinder SE50AX20S the Right Cylinder?
If your assembly requires slightly less thrust, the 40 mm bore variant provides 628 N of push at 0.5 MPa, whereas stepping up to the 63 mm bore yields 1559 N for heavier payloads. Because the stroke is only 20 mm, side-load stress on the M16x1.5 rod thread is minimal, though long unsupported strokes would necessitate an external guide. Remember that this standard cylinder relies on live air pressure to move; it does not hold position when air is exhausted. For drop-in retrofits, match the 50 mm bore, 20 mm stroke, PT1/4 port, and your required mounting accessory, ensuring the -S magnet is specified for sensor feedback.
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 SE50AX20S FAQ
At 0.5 MPa, the SE50AX20S provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force is 1374 N. The maximum push force is 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE50AX20S is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 profile cylinders, provided you match the 50 mm bore, 20 mm stroke, PT1/4 port, and mounting interface. The built-in magnet also works with AirTAC CMSE and DMSE sensors.
