About the Airtac SE50 Standard Cylinder SE50AX25S
The AirTAC SE50AX25S is a double-acting, single-rod ISO 15552 profile cylinder engineered for short-stroke actuation in demanding environments. It delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for compact, high-cycling operations. The extruded aluminum barrel features a square profile without external tie rods, which keeps the body corrosion-resistant and allows flush mounting on machinery frames.
This specific configuration includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion and washdown resistance, alongside a built-in magnet (code S) for position sensing. The integrated magnet enables direct mounting of AirTAC CMSE reed and DMSE electronic sensors directly into the three-sided sensor grooves, ensuring reliable end-of-stroke detection without requiring external brackets.

Where the Airtac SE50 Standard Cylinder SE50AX25S Is Used
Flow Wrapper End-Seal Jaw
Drives the rotary or reciprocating sealing jaw on a continuous flow wrapper, utilizing the 982 N push force and 25 mm stroke for precise, high-speed film crimping in food packaging lines.
Lab Sample Dispensing Valve
Actuates a pinch valve or nozzle for chemical sample dispensing, where the SUS420J2 stainless steel rod resists moisture and corrosive vapors in laboratory environments.
PCB Router Clamping Gate
Manages the entry gate of a PCB routing station, using the integrated DMSE sensor signal to confirm the clamp position before the spindle begins its routing cycle.
Is the Airtac SE50 Standard Cylinder SE50AX25S the Right Cylinder?
At a 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force. If your application requires less force, stepping down to the 40 mm bore yields 628 N of push, while stepping up to the 63 mm bore provides 1559 N to handle heavier loads. Because the 25 mm stroke is very short, side-load stress on the rod bearing is minimal, though any external lateral loads should still be supported by a guide to prevent seal wear. As a true ISO 15552 cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders, sharing the same mounting hardware, PT1/4 port, and M16x1.5 rod thread. Note that the field-adjustable air cushions at both ends decelerate the piston near stroke end but do not lock the load; if position holding is required without live air pressure, consider a BSE rod lock variant.
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 SE50AX25S FAQ
The SE50AX25S operates at 0.15-1.0 MPa and features a PT1/4 port. It generates 982 N of push force and 825 N of pull force at 0.5 MPa, 1374 N of push at 0.7 MPa, and reaches a maximum push of 200 kgf at 1.0 MPa.
No, the SE50AX25S is a standard double-acting cylinder and will drift if air is exhausted or pressure is lost. The field-adjustable air cushions at both ends only decelerate the piston near the stroke ends; they do not lock the rod. For true position holding, an AirTAC BSE rod lock variant is required.
