About the Airtac SE50 Standard Cylinder SE50AX850S
The AirTAC SE50AX850S is a double-acting single-rod profile cylinder built to the ISO 15552 standard. It features an 850 mm stroke and delivers a robust 982 N push force at 0.5 MPa. Equipped with a SUS420J2 stainless steel rod, it is specifically designed for corrosive or washdown environments where standard carbon steel rods would fail.
This model includes a built-in magnet for position sensing and utilizes a clean, square extruded aluminum barrel without external tie rods. This design not only prevents corrosion traps but also allows for flush mounting. The field-adjustable air cushioning at both ends can be tuned to absorb the kinetic energy of the piston as it approaches the stroke endpoints.

Where the Airtac SE50 Standard Cylinder SE50AX850S Is Used
Bottling Line Diverter
Pushes heavy product cases across a washdown conveyor belt using its 982 N force and 850 mm stroke, relying on the SUS420J2 rod to withstand daily moisture exposure.
Pallet Stretch Wrapper
Extends 850 mm to position the film carriage around large pallets, utilizing the adjustable cushioning to soften the end stops at high cycling speeds.
Chemical Sample Extraction
Actuates a dipping probe into corrosive vats where the stainless steel rod material prevents pitting and ensures reliable extraction over a long 850 mm reach.
Is the Airtac SE50 Standard Cylinder SE50AX850S the Right Cylinder?
When sizing this 50 mm bore, you can step down to a 40 mm bore for 628 N push at 0.5 MPa, or step up to a 63 mm bore for 1559 N push at 0.5 MPa. Because this model has an 850 mm stroke, which exceeds the standard maximum of 1200 mm for this bore, it is a non-standard made-to-order item. At this extended length, the 20 mm rod is subject to bending under side loads; an external guide mechanism is strongly recommended to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders for seamless retrofits. Note that a plain SE cylinder does not hold its position or load when air pressure is lost or exhausted; the piston will drift. If your application requires static load holding without live pressure, consider the BSE rod lock variant. This configuration includes the -S magnet for CMSE reed or DMSE electronic sensors, a PT1/4 port, and an M16x1.5 rod thread.
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 SE50AX850S FAQ
