About the Airtac SAI100 Standard Air Cylinder SAI100AX15S
The AirTAC SAI100X15-S is a double-acting ISO 15552 profile cylinder engineered for high-force, short-stroke operations. It delivers a robust 3927N of thrust at 0.5 MPa and operates at speeds between 30-800 mm/s. This specific configuration features a 15mm stroke, making it exceptionally well-suited for compact clamping and pressing tasks where space is strictly limited.
Built with an extruded aluminum barrel and equipped with a SUS420J2 stainless steel rod (material code A), this model provides excellent durability against moisture and minor corrosion. The integrated -S magnet allows seamless use with CMSE and DMSE sensor switches fitted into the dual-side grooves on the barrel. It utilizes PT tapered port threads and includes adjustable air cushions at both ends to manage impact forces effectively.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX15S Is Used
Heavy-Duty Clamping
Ideal for securing heavy metal workpieces during machining operations, utilizing the 3927N push force to hold parts rigidly against a fixed stop.
Short-Stroke Pressing
Perfect for inserting bearings or pins into housings where a brief, high-impact linear motion is required within a compact assembly cell.
Part Ejection
Provides a rapid, forceful ejection mechanism for finished parts from heavy machinery, using the integrated magnet and CMSE sensors to confirm ejection.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX15S the Right Cylinder?
Selecting this 100mm bore cylinder is optimal when your application demands substantial thrust within a highly constrained footprint. If you require less force, stepping down to an 80mm bore yields 2513N at 0.5 MPa, whereas moving up to a 125mm bore provides 6136N at 0.5 MPa. The 15mm stroke is a non-standard length, meaning you must verify your dead-space requirements to ensure the piston can complete its work within the available stroke distance.
Because the stroke is so short, side-load stress on the rod bearing is minimal compared to longer strokes. However, remember that a standard SAI cylinder relies entirely on pneumatic pressure to maintain its position. If your clamping or pressing application must hold a load safely during an air loss or emergency stop, you must integrate an external pilot-operated check valve or transition to the SAIL (air-released lock) or BSAI (clamp-lock) variant. For mounting, this unit is dimensionally interchangeable with other ISO 15552 cylinders and supports FA/FB flanges, TC trunnions, and LB foot brackets.
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 SAI100AX15S FAQ
This 100mm bore cylinder generates 3927N of push force and 3681N of pull force at a standard operating pressure of 0.5 MPa. At 0.7 MPa, the push force increases to 5497N.
Yes, the SAI100X15-S is a genuine ISO 15552 profile cylinder, making its mounting interface and dimensions interchangeable with other ISO 15552 cylinders from brands like Festo or SMC. You should match the bore, stroke, and PT port size for a seamless drop-in replacement.
