Airtac SE50 Standard Cylinder SE50X90
The AirTAC Airtac SE50 Standard Cylinder SE50X90 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø50mm bore and 90mm 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 SE50X90
The AirTAC SE50X90 is a double-acting single-rod ISO 15552 profile cylinder with a 50 mm bore and 90 mm stroke. It provides 982 N of push force at 0.5 MPa and uses a PT1/4 port. The extruded aluminum barrel has no external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This SKU lacks the built-in magnet option, meaning it does not support CMSE or DMSE electronic position sensors out of the box. Field-adjustable air cushions at both ends allow you to tune end-of-stroke deceleration, protecting tooling during rapid 30-800 mm/s cycles.

Where the Airtac SE50 Standard Cylinder SE50X90 Is Used
CNC Fixture Clamping
Provides 982 N of push force at 0.5 MPa to secure aluminum castings inside CNC milling fixtures during machining.
Carton Flap Folding
Uses the 90 mm stroke to rapidly fold corrugated cardboard side flaps on a continuous flow packaging line.
Belt Diverter Gate
Pivots a sorting arm to deflect plastic bottles into secondary packaging lanes on a conveyor belt.
Is the Airtac SE50 Standard Cylinder SE50X90 the Right Cylinder?
If 982 N is too much force, step down to the 40 mm bore which yields 628 N push at 0.5 MPa. If you need more thrust, step up to the 63 mm bore which provides 1559 N push. As a standard ISO 15552 cylinder, this 50 mm bore with PT1/4 porting and a 90 mm stroke is dimensionally interchangeable with other ISO 15552 profile cylinders, making it a direct drop-in retrofit. Remember that a plain SE cylinder does not hold a load if air pressure is lost; for position holding, 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 SE50X90 FAQ
The SE50X90 provides 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum push of 200 kgf at 1.0 MPa.
This specific SKU lacks the built-in magnet (-S option), so it cannot support CMSE reed or DMSE electronic sensors. You would need the SE50X90S variant for position sensing.
