About the Airtac SAI50 Standard Cylinder SAI50X280
The AirTAC SAI50X280 is a double-acting ISO 15552 profile cylinder offering a 982 N push force at 0.5 MPa. Its extruded aluminum barrel omits tie rods to provide a clean, standardized mounting interface that drops in seamlessly with other ISO 15552 cylinders. The 280 mm stroke is well suited for medium-travel material handling and packaging tasks.
To match your environment, the standard piston rod is carbon steel, and you can specify NBR or Viton high-temperature seals. The barrel features sensor grooves on both sides for CMSE or DMSE switches, though a magnet (-S option) is required for magnetic sensing.

Where the Airtac SAI50 Standard Cylinder SAI50X280 Is Used
Packaging Diverter
Pushes medium-weight cartons across a 280 mm transfer gap with 982 N of force at 0.5 MPa.
Parts Ejector
Stamps and ejects molded components from a press bed using a 280 mm travel distance.
Pallet Stopper
Acts as a mid-stroke stop for incoming pallets on a roller conveyor, absorbing kinetic energy.
Is the Airtac SAI50 Standard Cylinder SAI50X280 the Right Cylinder?
This 50 mm bore generates 982 N at 0.5 MPa, sitting neatly between the 40 mm bore (628 N) and the 63 mm bore (1559 N). Choose the SAI50X280 when your load falls in the 900-1000 N range. Because the 280 mm stroke creates an extended unsupported rod length, side loads can cause rod-bearing bending; use an external guide rail or a guided cylinder to prevent premature wear.
Air pressure loss will cause the piston to drift, as the adjustable air cushions only decelerate the piston near stroke ends rather than locking it. For drop prevention, specify the SAIL variant or an external rod lock. This model uses a PT tapered G1/4 port, standard 50 mm ISO 15552 mounting accessories, and requires the -S magnet for sensors.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for 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 (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI50 Standard Cylinder SAI50X280 FAQ
