About the Airtac SAI200 Standard Cylinder SAI200AX225
The AirTAC SAI200X225 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. With a 200mm bore and 225mm stroke, it generates a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa. This stroke length is ideal for large mold handling or substantial press operations requiring massive displacement.
Built with an extruded aluminum barrel, this unit omits tie-rods for a clean exterior while providing standardized ISO 15552 mounting dimensions. As configured here, it features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance, utilizes PT tapered port threads, and is prepared for demanding industrial environments.

Where the Airtac SAI200 Standard Cylinder SAI200AX225 Is Used
Heavy Stamping Presses
Provides the 15708 N push force at 0.5 MPa needed to drive large metal forming and stamping presses in heavy industrial lines.
Large Mold Handling
Utilizes the 225mm stroke to shift substantial injection molds or heavy tooling blocks into position securely within machining centers.
Automotive Assembly Jigs
Delivers reliable clamping and holding power for major automotive frame components during robotic welding and structural assembly.
Is the Airtac SAI200 Standard Cylinder SAI200AX225 the Right Cylinder?
This 200mm bore size sits at the top of the SAI range, offering maximum thrust. If an application requires slightly less force, stepping down to the 160mm bore yields 10053 N of push force at 0.5 MPa, which may save space and air consumption. At 225mm stroke, side load is moderate, but always ensure axial load alignment to prevent premature rod-bearing wear.
Because this is a double-acting cylinder, it requires continuous air pressure to hold position. If a sudden loss of supply pressure occurs, the load will drift or drop. For vertical loads requiring fail-safe holding, select the SAIL variant with an air-released lock, or the BSAI bidirectional clamp-lock cylinder. This SAI200X225 model is dimensionally interchangeable per ISO 15552, featuring a G3/4 port, M36x2 rod thread, and compatibility with CA/CB clevis and TC trunnion mounts.
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 SAI200AX225 FAQ
At an operating pressure of 0.5 MPa, the SAI200X225 delivers a push (extend) force of 15708 N and a pull (retract) force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X225 is a genuine AirTAC profile cylinder built to ISO 15552 dimensional standards. It serves as a drop-in replacement for other ISO 15552 cylinders of the same bore and stroke, provided you match the G3/4 port and mounting accessories.
