About the Airtac SAI125 Standard Air Cylinder SAI125X1100
The AirTAC SAI125X1100 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty linear motion. It provides a robust push force of 6136 N and a pull force of 5734 N at 0.5 MPa. Because the 1100 mm stroke exceeds the standard 1500 mm maximum for this bore, it is manufactured as a made-to-order unit to fit your specific long-travel machinery requirements.
This extruded aluminum profile barrel features integrated sensor grooves on both sides for direct mounting of CMSE or DMSE switches. To handle demanding thermal environments, you can select the NBR (N) seal option instead of the standard TPU, or choose Viton (H) for high-temperature resistance. The piston rod comes in standard carbon steel for maximum rigidity over this long stroke.

Where the Airtac SAI125 Standard Air Cylinder SAI125X1100 Is Used
Heavy Stamping
Drives large press dies over extended travel distances where 6136 N of push force is required to form thick metal components.
Pallet Transfer
Indexes heavy pallets along long assembly lines, utilizing the 1100 mm stroke to move parts between robotic workstations.
Bulk Material Gate
Actuates heavy-duty discharge gates on large silos, providing the sustained pulling power needed to move dense aggregate materials.
Is the Airtac SAI125 Standard Air Cylinder SAI125X1100 the Right Cylinder?
Choosing this 125 mm bore makes sense when the 100 mm class (3927 N push at 0.5 MPa) is insufficient for your load, but you want to avoid stepping up to the massive 160 mm frame. Operating speed for this bore is 30-500 mm/s. Because the 1100 mm stroke is non-standard and exceeds standard catalog limits, expect a slightly longer lead time for production.
With a 1100 mm stroke, the unsupported rod length is highly susceptible to bending under side loads. Use an external guide rail or a guided cylinder carriage to prevent rod-bearing damage. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not lock the load. If the application requires position holding without continuous air pressure, integrate an external pilot-operated check valve or select the SAIL (air-released lock) variant. This model uses a G1/2 (PT tapered) port and is dimensionally interchangeable per ISO 15552.
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 SAI125 Standard Air Cylinder SAI125X1100 FAQ
At 0.5 MPa, it provides 6136 N of push force and 5734 N of pull force. If you increase the operating pressure to 0.7 MPa, the push force reaches 8590 N.
Yes, the SAI125X1100 is a genuine ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 standard cylinders of the same bore size.
