About the Airtac SE50 Standard Cylinder SE50AX85
The AirTAC SE50AX85 is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and an 85 mm stroke. It delivers a robust 982 N push force at 0.5 MPa, making it well-suited for mid-range industrial actuation. The barrel utilizes a square extruded aluminum design without external tie rods, which keeps the body compact, corrosion-resistant, and easy to mount flush against machine frames.
This specific SKU features a SUS420J2 stainless steel rod (option A) for enhanced corrosion and washdown resistance. It operates at speeds of 30-800 mm/s using a PT1/4 port, and includes field-adjustable air cushioning at both ends to soften end-of-stroke impacts. Note that this configuration does not include a built-in magnet, meaning it is not wired for AirTAC CMSE or DMSE position sensors out of the box.

Where the Airtac SE50 Standard Cylinder SE50AX85 Is Used
Flow Wrapper End-Seal Jaw
Drives the sealing jaw on a continuous motion flow wrapper, utilizing the 982 N push force to crimp packaging film consistently at high cycle rates.
Bottling Line Diverter Gate
Actuates a pneumatic diverter arm on a bottling line, where the SUS420J2 stainless rod withstands daily washdown chemicals and moisture.
Metal Stamping Ejector
Ejects small stamped metal parts from a progressive die, relying on the 85 mm stroke and adjustable end cushions to prevent hard mechanical stops.
Is the Airtac SE50 Standard Cylinder SE50AX85 the Right Cylinder?
If your application requires less force, stepping down to a 40 mm bore yields a 628 N push at 0.5 MPa, whereas stepping up to a 63 mm bore provides 1559 N of thrust. This SE50AX85 is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other standard profile cylinders. Remember that the adjustable air cushion only decelerates the piston near the stroke end; it is not a locking mechanism. If the machine loses air pressure, the load will drift, requiring a BSE rod lock for secure holding. To match this exact unit, specify: 50 mm bore, 85 mm stroke, PT1/4 port, SUS420J2 rod, and no magnet.
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 SE50AX85 FAQ
The SE50AX85 delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa. At 0.7 MPa, the push force is 1374 N. The maximum push force is 200 kgf at 1.0 MPa. It operates at a speed range of 30-800 mm/s.
