About the Airtac SAI200 Standard Cylinder SAI200AX375S
The AirTAC SAI200X375-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 15708 N of push force at just 0.5 MPa, it leverages a 200 mm bore to move massive payloads reliably. The 375 mm stroke provides extensive travel for large-scale material handling. This unit features a built-in magnet (-S) for seamless integration with CMSE or DMSE reed switches, fitting directly into the extruded aluminum barrel's dual sensor grooves.
Equipped with a SUS420J2 stainless steel piston rod, this model offers superior resistance to corrosion and mechanical wear compared to standard carbon steel. The barrel utilizes an extruded aluminum profile design rather than traditional tie-rods, reducing overall weight while maintaining structural rigidity. It incorporates adjustable air cushions at both ends to decelerate heavy masses smoothly, operating efficiently at speeds of 30-500 mm/s.

Where the Airtac SAI200 Standard Cylinder SAI200AX375S Is Used
Heavy Metal Forming
Provides the immense 21991 N thrust at 0.7 MPa needed to actuate large stamping presses and heavy-gauge metal bending equipment.
Automotive Assembly
Drives large-scale robotic welding fixtures and heavy chassis positioning platforms where high mass and long travel are standard.
Pallet Handling
Pushes fully loaded industrial pallets along transfer lines, utilizing the 375 mm stroke to clear large conveyor lanes.
Is the Airtac SAI200 Standard Cylinder SAI200AX375S the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when applications require up to 15708 N of thrust at 0.5 MPa, or 21991 N at 0.7 MPa. If your system operates at lower pressures, this bore size ensures you still achieve substantial force. Conversely, stepping down to a 160 mm bore drops the 0.5 MPa thrust to 10053 N, which may be insufficient for extreme heavy lifting. The PT tapered port threads ensure a tight, leak-free pneumatic connection.
Because the 375 mm stroke generates significant side-load leverage, long unsupported rods are prone to bending under lateral stress. To prevent premature rod-bearing wear, implement an external guide rail or use a guided cylinder mechanism. Note that the adjustable cushions only decelerate the piston near stroke end; they do not lock the load. If your application requires absolute position holding during air loss, integrate an external pilot-operated check valve or select the SAIL lock variant.
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 SAI200 Standard Cylinder SAI200AX375S FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
No, the standard SAI cylinder does not hold its position when air pressure is lost. The adjustable air cushions only decelerate the piston at stroke end. For suspended load safety, use an external rod lock or the AirTAC SAIL variant with an air-released lock.
