About the Airtac SE50 Standard Cylinder SE50AX55
The AirTAC SE50AX55 is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and a 55 mm stroke. It delivers a robust 982 N push force at 0.5 MPa, utilizing a PT1/4 port and a 20 mm piston rod. Because this SKU uses code A, the rod is manufactured from SUS420J2 stainless steel, making the unit highly suitable for corrosive environments or washdown duty where a standard hard-chrome rod would fail.
The extruded aluminum barrel design omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion. Field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed cycling. Note that this specific configuration ships without a sensor magnet, so it does not directly support AirTAC CMSE or DMSE position switches without modification.

Where the Airtac SE50 Standard Cylinder SE50AX55 Is Used
Pouch Forming Diverter
Actuates a routing flap on a vertical form-fill-seal machine, using the 55 mm stroke and 982 N push to redirect pouches into secondary packaging lanes.
Lab Bottle Capping Head
Lowers a chuck onto pharmaceutical vials, relying on the SUS420J2 stainless rod to withstand frequent chemical washdowns without pitting.
Belt Tracking Tensioner
Maintains precise side-pressure on a food-grade conveyor belt drive, using the compact tie-rod-free profile to fit within narrow guard rails.
Is the Airtac SE50 Standard Cylinder SE50AX55 the Right Cylinder?
When sizing this actuator, compare its 982 N push at 0.5 MPa against your actual load requirements. If your application demands less force, stepping down to the 40 mm bore variant yields 628 N of push force, whereas stepping up to the 63 mm bore provides 1559 N for heavier payloads. As a standard ISO 15552 profile cylinder, this model serves as a direct replacement for any cylinder sharing the 50 mm bore footprint, utilizing standard mounting accessories like FA or LB brackets. Keep in mind that the adjustable air cushion only decelerates the piston near the stroke end; it is not a locking device. If the machine loses air pressure, the cylinder will drift, so a BSE rod lock variant is required for strict position holding.
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 SE50AX55 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. The maximum push capacity is 200 kgf at 1.0 MPa, and the operational speed range is 30-800 mm/s.
Yes. The SE50AX55 is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact mounting footprint and rod thread (M16x1.5) of other 50 mm profile cylinders. You can swap it directly without modifying the machine plate, provided your port matches the PT1/4 thread.
