About the Airtac SE50 Standard Cylinder SE50AX35
The AirTAC SE50AX35 is a double-acting, single-rod ISO 15552 profile cylinder engineered for compact 35 mm stroke tasks requiring robust linear force. Operating at 0.5 MPa, it generates 982 N of push force and 825 N of pull force, scaling up to a maximum of 200 kgf at 1.0 MPa. The extruded aluminum barrel lacks external tie rods, yielding a flush, corrosion-resistant exterior that mounts cleanly in tight machinery spaces.
This specific SKU features a SUS420J2 stainless steel piston rod (material code A) built for corrosive and washdown environments. It includes field-adjustable air cushioning at both ends to soften end-of-stroke impacts, though it carries no built-in magnet, meaning position sensing must be handled externally.

Where the Airtac SE50 Standard Cylinder SE50AX35 Is Used
Flow Wrapper Diverter
Handles short 35 mm product rejection strokes on stainless food-grade flow wrappers, utilizing the 982 N push force and SUS420J2 rod to withstand daily washdowns.
Lab Dispenser Head
Acts as a precise pneumatic dosing head for chemical dispensing racks, where the compact 50 mm bore and corrosion-resistant rod endure harsh reagent exposure.
PCB Test Fixture
Drives the moving platen in automated printed circuit board validation fixtures, applying controlled clamping via the adjustable end cushions to protect delicate electronics.
Is the Airtac SE50 Standard Cylinder SE50AX35 the Right Cylinder?
Choosing this 50 mm bore makes sense when a 40 mm cylinder (628 N push @0.5 MPa) is underpowered, but a larger 63 mm bore (1559 N push @0.5 MPa) would be physically excessive. The PT1/4 port and M16x1.5 rod thread are optimized for this force class. Because this is a standard double-acting cylinder, it cannot hold a load if air pressure is lost; applications requiring mid-stroke locking or fail-safe holding must pivot to the AirTAC BSE rod-lock variant. As a true ISO 15552 cylinder, it serves as a drop-in replacement for any matching profile cylinder without altering mounting footprints.
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 SE50AX35 FAQ
The SE50AX35 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 increases to 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s.
No, this specific SKU lacks the built-in magnet (no -S code) required for AirTAC CMSE or DMSE sensors. If you need position feedback, you must select an SE50 model with the 'S' option or use external mechanical limit switches.
