About the Airtac SAI200 Standard Cylinder SAI200AX250
The AirTAC SAI200X250 is a heavy-duty double-acting profile cylinder built to ISO 15552 dimensional standards. Delivering a massive 15708 N of push force at just 0.5 MPa, it is engineered for high-load industrial handling. This 250 mm stroke configuration provides the extended reach needed for large presses and heavy material transfer.
This unit features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in harsh environments. Fluid ports use a PT tapered thread type, and the extruded aluminum barrel includes dual sensor grooves. Note that this standard configuration omits the magnet; adding the -S option enables CMSE or DMSE sensor tracking.

Where the Airtac SAI200 Standard Cylinder SAI200AX250 Is Used
Heavy Press Operations
Provides the 15708 N thrust at 0.5 MPa required for actuating large industrial stamping and forming presses.
Large Assembly Jigs
Drives heavy-duty clamping mechanisms on automotive or structural steel assembly lines with a 250 mm stroke.
Bulk Material Diversion
Shifts heavy pallets or bulk material diverters on high-capacity conveying systems where high force is mandatory.
Is the Airtac SAI200 Standard Cylinder SAI200AX250 the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when 15708 N of thrust at 0.5 MPa is required, which is a significant step up from the 10053 N provided by the 160 mm bore variant. Because the stroke is 250 mm, you should evaluate the rod-bearing load; while under the 300 mm threshold for critical side-load warnings, maintaining proper alignment is still essential to prevent premature seal wear.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other standard cylinders sharing the same mounting interface. To hold a load safely without continuous air pressure, do not rely on the adjustable air cushions; instead, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock.
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.
