About the Airtac SAI100 Standard Air Cylinder SAI100X950
The AirTAC SAI100X950 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 950mm stroke. Because this stroke exceeds the standard maximum of 1500mm, it is manufactured as a made-to-order unit to fit specific long-travel machinery. It generates a push force of 3927 N at 0.5 MPa, making it well-suited for heavy-duty material handling and large press operations.
This model features a standard carbon steel piston rod and utilizes a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE or DMSE switches if you decide to integrate position sensing later. For applications requiring multi-directional clamping or locking without continuous air pressure, the related BSAI bidirectional clamp-lock series is a better choice.

Where the Airtac SAI100 Standard Air Cylinder SAI100X950 Is Used
Automotive Assembly Lines
Drives large lifting arms and heavy pallet shuttles over a 950mm travel distance, utilizing the 3927 N push force to move chassis components reliably.
Large Press Ejection
Provides the long stroke and robust push power needed to eject bulky formed parts from heavy machinery, ensuring complete removal before the next cycle.
High-Bay Material Handling
Actuates vertical lifting platforms in automated storage systems, where the 100mm bore delivers the necessary thrust to elevate heavy totes.
Is the Airtac SAI100 Standard Air Cylinder SAI100X950 the Right Cylinder?
With a 100mm bore providing 3927 N of thrust at 0.5 MPa, stepping down to an 80mm bore drops the force to 2513 N, while moving up to a 125mm bore increases it to 6136 N. Choose this size when your load requires substantial push power over a long distance.
Because the 950mm stroke creates a long unsupported rod extension, side loads can cause severe bending stress on the rod bearing. To prevent premature wear, guide the load externally or use a guided cylinder system. Note that the standard SAI does not hold position if air pressure is lost; use the SAIL variant with an air-released lock for fail-safe load holding. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders using a G1/2 port, foot mounting (LB), and no magnet.
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 SAI100X950 FAQ
