About the Airtac SAI100 Standard Air Cylinder SAI100X1250S
The AirTAC SAI100X1250-S is a double-acting ISO 15552 profile cylinder engineered for extended travel distances. Delivering a push force of 3927 N at 0.5 MPa, this 100mm bore unit handles heavy linear loads. The 1250mm stroke is a made-to-order specification exceeding the standard 1500mm maximum, tailored for specialized automation layouts.
This configuration includes a magnet for CMSE and DMSE sensor integration, fitting directly into the dual-sided extruded aluminum barrel groove. The piston rod is constructed from carbon steel for high tensile strength, and the PT tapered port threads guarantee a rigid, leak-free pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100X1250S Is Used
Extended Material Transfer
Drives long-stroke pushers on automated assembly lines, moving heavy pallets or components across wide workstation gaps with a steady 3927 N force.
Large Press Handling
Actuates heavy lifting platforms or press ejectors where a 1250mm travel distance is required to clear large tooling or molds completely.
High-Reach Elevators
Operates vertical lifting mechanisms in automated storage systems, utilizing the integrated magnet for precise top and bottom position sensing.
Is the Airtac SAI100 Standard Air Cylinder SAI100X1250S the Right Cylinder?
For applications requiring less force, the 80mm bore offers 2513 N at 0.5 MPa, whereas the 125mm bore provides 6136 N for heavier demands. Because this 1250mm stroke generates significant extension, an external guide rail or guided cylinder is strongly recommended to prevent rod-bearing bending and premature seal wear under side loads.
As a true ISO 15552 profile cylinder, it provides a drop-in mounting interface interchangeable with other ISO 15552 cylinders. Standard mounting accessories include FA/FB flanges and TC trunnions. If the machinery requires fail-safe load holding upon air loss, integrate the SAIL variant or an external rod lock, as standard air cushions only decelerate the piston at stroke end.
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 SAI100 Standard Air Cylinder SAI100X1250S FAQ
At 0.5 MPa operating pressure, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI series is dimensionally interchangeable per ISO 15552 profile barrel standards. You can drop it into existing foot, flange, or trunnion mounts designed for ISO 15552 cylinders.
