About the Airtac SE50 Standard Cylinder SE50AX50S
The AirTAC SE50AX50S is a double-acting, single-rod ISO 15552 profile cylinder engineered for precise linear motion. Delivering 982 N of push force at 0.5 MPa, it features a 50 mm bore and a 50 mm stroke. This variant utilizes a SUS420J2 stainless steel rod (code A), making it highly suitable for corrosive or washdown environments where standard carbon steel rods would degrade.
The extruded aluminum barrel design omits external tie rods, yielding a smooth, compact body that mounts flush against machine frames while resisting corrosion. Field-adjustable pneumatic cushioning at both ends allows technicians to fine-tune end-of-stroke deceleration via a set screw, effectively softening hard mechanical stops during high-speed operations.

Where the Airtac SE50 Standard Cylinder SE50AX50S Is Used
Flow Wrapper Sealing Jaws
Drives the reciprocating sealing head on continuous motion flow wrappers, using the 50 mm stroke and 982 N push force to cleanly crimp and sever packaging film at high cyclic rates.
Diverter Gate Actuation
Pivots routing flaps on modular conveyor lines; the SUS420J2 stainless rod withstands incidental splash and washdown in food or pharmaceutical transfer zones.
PCB Router Z-Axis Lift
Raises and lowers the spindle on light CNC printed circuit board routers, relying on adjustable end cushions to soften direction reversals and protect the delicate cutting bit.
Is the Airtac SE50 Standard Cylinder SE50AX50S the Right Cylinder?
When sizing this actuator, consider stepping down to a 40 mm bore (628 N push at 0.5 MPa) for lighter duties, or up to a 63 mm bore (1559 N push at 0.5 MPa) if your load requires significantly more extension force. Remember that a standard SE cylinder relies on live air pressure to hold its position; if air is exhausted, the piston will drift, so a BSE rod lock variant is necessary for strict fail-safe holding.
As a true ISO 15552 cylinder, the SE50AX50S is dimensionally interchangeable with other ISO 15552 profile cylinders, allowing seamless retrofitting using existing mounting hardware. This specific unit includes a built-in magnet (code S) for position sensing with AirTAC CMSE reed or DMSE electronic switches, and uses a PT1/4 port.
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 SE50AX50S FAQ
The SE50AX50S 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 is 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. It features a 50 mm bore, 50 mm stroke, PT1/4 port, M16x1.5 rod thread, and operates at speeds of 30-800 mm/s.
