About the Airtac SE50 Standard Cylinder SE50AX500SH
The AirTAC SE50AX500SH is a double-acting single-rod ISO 15552 profile cylinder engineered for demanding environments. It generates 982 N of push force at 0.5 MPa and features a SUS420J2 stainless steel rod paired with a Viton (FKM) seal, expanding the operating temperature range up to 150 C for washdown or high-heat duty.
Built with an extruded aluminum barrel that eliminates external tie rods, this unit offers a flush mounting surface and superior corrosion resistance. The integrated magnet (-S) supports CMSE reed and DMSE electronic position sensors, while the field-adjustable air cushioning at both ends allows you to dial in end-of-stroke deceleration for the 500 mm travel.

Where the Airtac SE50 Standard Cylinder SE50AX500SH Is Used
Medical Autoclave Doors
Lifts and seals heavy sterilizer chamber doors, utilizing the Viton seal and SUS420J2 rod to withstand 150 C steam environments while providing 982 N of push force.
Bottling Line Diverters
Actuates high-speed routing gates on beverage lines over its 500 mm stroke, where the flush profile barrel resists washdown chemicals and the adjustable cushion softens gate impacts.
CNC Tool Changer Arms
Drives linear tool storage carriages, relying on DMSE electronic sensors for precise positioning and the stainless rod to resist coolant mist and corrosion.
Is the Airtac SE50 Standard Cylinder SE50AX500SH the Right Cylinder?
Selecting this 50 mm bore yields 982 N push at 0.5 MPa. If your application requires less force, stepping down to the 40 mm bore provides 628 N of push; conversely, scaling up to the 63 mm bore offers 1559 N. Because this model carries a 500 mm stroke, the unsupported piston rod is subject to bending under lateral loads—always pair it with an external guide to prevent rod-bearing wear.
This cylinder is dimensionally interchangeable per ISO 15552, serving as a direct drop-in replacement for other ISO 15552 cylinders using the same 50 mm bore, 500 mm stroke, PT1/4 port, and mounting accessories. Note that the adjustable air cushion only decelerates the piston near stroke end; it does not lock the rod, so an external rod lock or pilot-operated check valve is required to hold a load safely without live air pressure.
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 SE50AX500SH FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of 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. Thanks to the Viton (FKM) seal, it operates reliably in temperatures up to 150 C.
Yes, it is dimensionally interchangeable per ISO 15552, meaning it serves as a drop-in replacement for other standard ISO 15552 profile cylinders. However, the adjustable air cushion only decelerates the piston near the stroke end and does not function as a brake; you must use an external rod lock to hold a load without live air pressure.
