Airtac SE50 Standard Cylinder SE50AX325
The AirTAC Airtac SE50 Standard Cylinder SE50AX325 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø50mm bore and 325mm stroke, PT1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE50 Standard Cylinder SE50AX325
The AirTAC SE50AX325 is a double-acting single-rod profile cylinder built to ISO 15552 dimensions, delivering 982 N of push force at 0.5 MPa and a 325 mm stroke. It features a SUS420J2 stainless steel rod (code A) specifically selected for corrosive environments or washdown duty. The square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion.
This model lacks a built-in magnet, meaning it is not equipped for CMSE or DMSE position sensing out of the box. To protect the rod and end caps from impact, it relies on field-adjustable pneumatic cushioning at both ends. You can tune the cushion screws to smoothly decelerate the piston as it approaches the 30 mm cushion length at stroke end.

Where the Airtac SE50 Standard Cylinder SE50AX325 Is Used
Bottle Rinser Gripper
Utilizes the SUS420J2 stainless rod to withstand caustic washdown chemicals while actuating gripper arms that lift and invert bottles through a 325 mm arc.
Case Pusher Assembly
Provides 982 N of push at 0.5 MPa to index filled cartons onto a sealing conveyor, relying on the adjustable cushion to soften the end-of-stroke impact.
Diverter Gate Actuator
Drives a routing flap for sorting mixed product lines, where the tie-rod-free extruded profile allows flush mounting directly to the conveyor side frame.
Is the Airtac SE50 Standard Cylinder SE50AX325 the Right Cylinder?
Choose this 50 mm bore when you need 982 N push at 0.5 MPa; if your load is lighter, step down to the 40 mm bore (628 N push), or step up to the 63 mm bore (1559 N push) for heavier demands. As a standard ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders using the same 325 mm stroke and PT1/4 port. Because this SKU lacks the -S magnet, you must add external limit switches or choose an -S variant if your application requires CMSE or DMSE electronic position feedback.
With a 325 mm stroke, the unsupported piston rod is subject to bending forces under side loads. To prevent premature rod-bearing wear, implement an external guide rail to carry the load and ensure the cylinder only supplies linear thrust.
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 SE50AX325 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 is 1374 N. The maximum push force is 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the SE50AX325 is a standard double-acting cylinder and will drift if air is lost or the valve is centered. The adjustable air cushion at both ends only decelerates the piston near the stroke ends; it does not lock the rod. For position holding, you need a BSE rod lock variant or an external pilot-operated check valve.
