Airtac SE50 Standard Cylinder SE50X75
The AirTAC Airtac SE50 Standard Cylinder SE50X75 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø50mm bore and 75mm 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 SE50X75
The AirTAC SE50X75 is a double-acting, single-rod ISO 15552 profile cylinder engineered to deliver a 982 N push force at 0.5 MPa and a 1374 N push at 0.7 MPa. Because it features a square extruded aluminum barrel without external tie rods, it provides a compact, corrosion-resistant body that mounts flush against machine frames, simplifying spatial constraints in tight assemblies.
This 50 mm bore unit operates at speeds from 30-800 mm/s and utilizes a PT1/4 port. The field-adjustable air cushioning at both ends allows technicians to tune the end-of-stroke deceleration via a screw, softening hard mechanical stops during high-speed cycling. Note that this specific SKU lacks a built-in magnet, so it does not support CMSE or DMSE position sensing out of the box.

Where the Airtac SE50 Standard Cylinder SE50X75 Is Used
Flow Wrapper End-Seal Press
Drives the upper sealing jaw on continuous-motion flow wrappers, using the 982 N push force to cleanly crimp packaging film seams at cycle speeds up to 800 mm/s.
Palletizing Stop Gate
Acts as a pneumatic stop gate in low-profile pallet conveyors, extending 75 mm to halt cartons precisely for robotic pick-and-place operations.
Lab Centrifuge Lid Lock
Provides secure, repeatable clamping on laboratory centrifuge safety covers, where the clean extruded barrel prevents debris buildup and the adjustable cushion prevents harsh slamming.
Is the Airtac SE50 Standard Cylinder SE50X75 the Right Cylinder?
If 982 N of push at 0.5 MPa is too much force for your application, step down to the 40 mm bore (628 N push). If your payload requires more thrust, step up to the 63 mm bore (1559 N push). As a true ISO 15552 cylinder, this unit is dimensionally interchangeable with other ISO 15552 profile cylinders, making it a seamless drop-in retrofit that reuses existing mounting hardware like LB foot brackets or FA front flanges.
Remember that a standard SE cylinder does not hold its load when air pressure is lost or the valve is centered; the piston will drift. If your application requires static holding without live air pressure, consider the BSE rod-lock variant. Additionally, this 75 mm stroke keeps the unsupported rod length short, minimizing rod-bearing bending, but any future upgrades to longer strokes should incorporate an external guide to manage side loads.
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 SE50X75 FAQ
The SE50X75 has a 50 mm bore and uses a PT1/4 port. It generates 982 N of push force and 825 N of pull force at 0.5 MPa. At 0.7 MPa, the push force is 1374 N. The maximum push force is 200 kgf (1961 N) at the maximum operating pressure of 1.0 MPa.
No, this specific SE50X75 SKU is manufactured without a built-in magnet (-S code omitted). To use AirTAC CMSE reed or DMSE electronic position sensors in the barrel's sensor grooves, you must select the SE50X75S variant which includes the internal magnetic piston ring.
