About the Airtac SE50 Standard Cylinder SE50AX5
The AirTAC SE50AX5 is a double-acting single-rod ISO 15552 profile cylinder engineered for short-stroke automation. It delivers a robust 982 N push force at 0.5 MPa alongside an 825 N pull, utilizing a 20 mm diameter rod with an M16x1.5 thread. This specific SKU features a SUS420J2 stainless steel rod (code A), making it highly suitable for corrosive environments or washdown duty where standard carbon steel rods would degrade.
Its square extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion. The cylinder includes field-adjustable air cushioning at both ends to decelerate the piston near stroke end, though it lacks a built-in position sensor magnet on this specific configuration.

Where the Airtac SE50 Standard Cylinder SE50AX5 Is Used
Flow Wrapper End-Sealing
Drives the short 5 mm stroke sealing jaw on continuous flow packaging lines, utilizing the 982 N push force to cleanly crimp film seams in washdown environments.
Lab Sample Dispensing
Actuates a 5 mm micro-dose valve for chemical reagent dispensing, relying on the SUS420J2 stainless rod to resist corrosive vapor exposure.
PCB Component Press
Performs a brief 5 mm contact stroke to seat through-hole connectors onto circuit boards, applying precise 0.5 MPa clamping without damaging fragile substrates.
Is the Airtac SE50 Standard Cylinder SE50AX5 the Right Cylinder?
For sizing flexibility, stepping down to a 40 mm bore drops the 0.5 MPa push force to 628 N, while stepping up to a 63 mm bore increases it to 1559 N. Because this is a plain double-acting cylinder, it cannot hold a load if air pressure is lost or the valve is centered; the piston will drift. For applications requiring mid-stroke locking, consider the BSE variant or an external pilot-operated check valve.
Being dimensionally interchangeable per ISO 15552, this cylinder serves as a drop-in replacement for other ISO 15552 profile cylinders. Ensure your setup matches the 50 mm bore, 5 mm stroke, PT1/4 port, and desired mounting accessory. The 30 mm cushion length effectively absorbs kinetic energy at the 30-800 mm/s operating speed range.
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 SE50AX5 FAQ
The SE50AX5 has a 50 mm bore and uses a PT1/4 port. It generates 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum push of 200 kgf at 1.0 MPa.
No, the SE50AX5 is a standard double-acting cylinder and the piston will drift if air is exhausted. The adjustable air cushion only decelerates the piston near the stroke ends; it does not lock the load. For true position holding, explore the BSE rod lock variant.
