About the Airtac SAI200 Standard Cylinder SAI200AX375
The AirTAC SAI200X375 is a double-acting ISO 15552 profile cylinder engineered for extreme heavy-duty automation. Operating at 0.5 MPa, it generates a substantial push force of 15708 N, making it suitable for moving massive payloads. The 375 mm stroke provides the extended travel distance required for large-scale material handling. This model features a SUS420J2 stainless steel rod (option A) for superior corrosion and wear resistance in harsh environments.
Unlike traditional tie-rod designs, this extruded aluminum profile barrel integrates sensor grooves on both sides for direct CMSE or DMSE switch mounting. However, because no magnet (-S) is specified, adding sensors will require a magnetic piston. For applications needing controlled deceleration at high speeds, the adjustable air cushions at both ends deliver 50 mm of cushioning length to absorb kinetic energy smoothly.

Where the Airtac SAI200 Standard Cylinder SAI200AX375 Is Used
Heavy Metal Forming
Provides the immense 15708 N push force required to actuate large mechanical presses and heavy-gauge metal forming dies at 0.5 MPa.
Large Press Demolding
The 375 mm stroke offers the deep extraction travel needed to pull large molded composite or metal parts safely out of heavy industrial presses.
Bulk Material Diversion
Drives massive automated diverter arms on heavy-duty mining or bulk aggregate conveyor lines, easily moving dense, high-volume loads.
Is the Airtac SAI200 Standard Cylinder SAI200AX375 the Right Cylinder?
Selecting this 200 mm bore is appropriate when the 160 mm bore (providing 10053 N push at 0.5 MPa) lacks the necessary thrust for your heaviest fixtures. Because the 375 mm stroke exceeds 300 mm, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or utilize a fully guided cylinder to absorb lateral forces.
This SAI200X375 utilizes G3/4 PT tapered ports and is dimensionally interchangeable per ISO 15552, serving as a direct drop-in replacement for other ISO 15552 cylinders. Mounting accessories include TC trunnion or FA flange options. Remember that the standard SAI does not hold its position if air pressure is lost; for fail-safe load holding without live pressure, specify the SAIL variant with an air-released lock or an external rod 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.
Airtac SAI200 Standard Cylinder SAI200AX375 FAQ
At a 0.5 MPa operating pressure, the SAI200X375 generates a push force of 15708 N and a pull force of 15080 N. At the maximum 1.0 MPa pressure, it can deliver a theoretical maximum force of 3204 kgf.
Yes, for a 375 mm stroke, using external guide rails or a guided cylinder body is strongly recommended. Long unsupported rods are prone to bending under side loads, and proper external guidance prevents rod-bearing damage and ensures smooth operation.
