About the Airtac SAI200 Standard Cylinder SAI200AX50
The AirTAC SAI200X50 is a double-acting ISO 15552 profile cylinder engineered for immense thrust, delivering 15708 N of push force at just 0.5 MPa. Its 50 mm stroke is tailored for high-force clamping, pressing, and short-stroke heavy-duty positioning tasks.
This unit features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance and structural integrity under heavy loads. Fluid ports feature PT tapered threading, and the extruded aluminum barrel includes dual sensor grooves for flexible switch placement.

Where the Airtac SAI200 Standard Cylinder SAI200AX50 Is Used
Heavy-Duty Stamping
Provides the massive 15708 N push force at 0.5 MPa needed for short-stroke metal forming and stamping operations.
Industrial Clamping
Ideal for securing large molds or heavy fabrications during machining, utilizing its 50 mm stroke for rapid, high-force actuation.
Press Fit Assembly
Drives large bearings or bushings into heavy housings, leveraging the 3204 kgf theoretical maximum force at 1.0 MPa.
Is the Airtac SAI200 Standard Cylinder SAI200AX50 the Right Cylinder?
Select this 200 mm bore when 160 mm (10053 N at 0.5 MPa) cannot generate the required push force. The 50 mm stroke keeps the retracted length compact, minimizing rod-bearing bending stresses. For applications requiring position retention during a loss of air pressure, the SAIL pneumatic lock variant or an external rod lock is required, as the standard air cushion only decelerates the piston at stroke end.
This model serves as a drop-in replacement for any ISO 15552 cylinder with matching 200 mm bore, 50 mm stroke, G3/4 PT ports, and standard mounting accessories like TC trunnion or FA flange.
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.
