About the Airtac SAI200 Standard Cylinder SAI200AX270
The AirTAC SAI200X270 is a robust double-acting profile cylinder built to the ISO 15552 standard, delivering immense thrust for heavy-duty pneumatics. It provides a substantial push force of 15708 N at 0.5 MPa and a pull force of 15080 N. The 270 mm stroke is ideal for moving large masses or actuating heavy industrial assemblies.
This unit features an extruded aluminum barrel without tie-rods, incorporating sensor grooves on both sides for flexible position detection. Configured with a SUS420J2 stainless steel piston rod (material code A), it offers superior resistance to corrosion and moisture. The PT tapered port threads ensure a tight, reliable pneumatic connection in high-flow applications.

Where the Airtac SAI200 Standard Cylinder SAI200AX270 Is Used
Heavy Stamping
Generates the 15708 N force needed to drive large metal forming and stamping presses at 0.5 MPa.
Plastic Molding
Actuates heavy mold halves and large clamping fixtures requiring a 270 mm stroke and high stability.
Bulk Material Handling
Shifts large bulk material gates or heavy palletized loads in rugged logistics and manufacturing environments.
Is the Airtac SAI200 Standard Cylinder SAI200AX270 the Right Cylinder?
This 200 mm bore class provides the maximum standard thrust in the SAI lineup, delivering 15708 N at just 0.5 MPa. If your application requires less force, stepping down to the 160 mm bore yields 10053 N at the same pressure, optimizing air consumption.
Because the 270 mm stroke exceeds the 300 mm threshold, it is critical to manage side loads. Long unsupported rods are prone to bending under lateral forces; use an external guide rail or a fully guided cylinder to prevent premature rod-bearing wear. Additionally, this standard SAI cylinder will drift if air pressure is lost. For applications requiring position holding without live pressure, select the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. As an ISO 15552 profile cylinder, it serves as a direct dimensional replacement for any standard 200 mm bore, 270 mm stroke ISO 15552 cylinder with a G3/4 port and matching mounting accessories.
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.
