About the Airtac SE50 Standard Cylinder SE50AX135S
The AirTAC SE50AX135S is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 50mm bore and 135mm stroke. It provides a robust 982N push force at 0.5 MPa, utilizing a PT1/4 port and a 20mm piston rod with an M16x1.5 thread. Because it features a SUS420J2 stainless steel rod (code A), this specific configuration is tailored for corrosive environments and washdown duty where standard carbon steel rods would degrade prematurely.
The extruded aluminum barrel design omits external tie rods, yielding a smooth, compact profile that prevents debris accumulation and allows sensors to be mounted flush along three integrated grooves. Equipped with a built-in magnet (code S), the cylinder seamlessly integrates with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. Furthermore, the field-adjustable pneumatic cushioning at both ends allows technicians to fine-tune end-cap deceleration via a set screw, effectively minimizing mechanical shock during high-speed 30-800 mm/s operations.

Where the Airtac SE50 Standard Cylinder SE50AX135S Is Used
Flow Wrapper End-Seal Jaws
Drives the rotary and reciprocating sealing jaws on continuous-motion flow wrappers, utilizing the 982N push force to cleanly crimp and sever packaging film at speeds up to 800 mm/s.
Lab Sample Centrifuge Loader
Leverages the SUS420J2 stainless steel rod to withstand harsh chemical wipe-downs and biological spills while loading sample tubes into high-speed centrifuge rotors.
Printed Circuit Board Clamping
Secures PCBs during automated soldering and inspection processes, using the -S magnet and DMSE sensors to confirm precise 135mm stroke positioning for robotic arms.
Is the Airtac SE50 Standard Cylinder SE50AX135S the Right Cylinder?
When sizing this actuator, compare its 982N push at 0.5 MPa against your actual load dynamics. If your application requires less force, stepping down to the 40mm bore reduces the push output to 628N while saving space; conversely, scaling up to the 63mm bore increases the push capacity to 1559N for heavier lifting. Because the 135mm stroke falls below the 300mm threshold, standard rod-bearing bending is minimal, though extreme lateral loads still require an external guide. As a true ISO 15552 profile cylinder, this unit serves as a direct, drop-in dimensional replacement for any standard 50mm bore, 135mm stroke ISO 15552 cylinder, utilizing identical mounting hardware and PT1/4 ports. Note that the adjustable air cushion only decelerates the piston near stroke end; it does not hold the load if air pressure is lost.
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.
