About the Airtac SAI100 Standard Air Cylinder SAI100BX15S
The AirTAC SAI100X15-S is a double-acting ISO 15552 profile cylinder engineered for short-stroke, high-thrust tasks. It supplies 3927 N of push force at 0.5 MPa and 5497 N at 0.7 MPa. The 15 mm stroke is optimal for compact clamping or pressing operations where space is strictly limited.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE or DMSE sensor switches. As a genuine extruded aluminum profile barrel design, it drops directly into standardized ISO 15552 mounting footprints without requiring tie-rods.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX15S Is Used
Short-Stroke Pressing
Delivers 5497 N of thrust at 0.7 MPa for seating bearings or stamping small components within a tight 15 mm travel.
Heavy Clamping
Provides robust holding power for securing thick workpieces or pallets during machining operations.
Ejector Mechanism
Uses the high instantaneous force of the 100 mm bore to eject dense parts from molds quickly.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX15S the Right Cylinder?
Select this 100 mm bore when a 63 mm cylinder (1559 N at 0.5 MPa) lacks the necessary power for heavy pressing. The 15 mm stroke minimizes rod-bearing bending stress, making external guides less critical than on longer strokes. Because it is a standard double-acting cylinder, it will drift if air pressure is lost; use a SAIL variant if the application requires pneumatic locking.
To match this ISO 15552 interchangeable unit, specify the 100 mm bore, 15 mm stroke, PT tapered port threads, and the -S magnet option. Mounting accessories include LB foot brackets, FA flanges, or TC trunnion styles depending on your load pivot requirements.
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 SAI100BX15S FAQ
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X15-S is dimensionally interchangeable per ISO 15552. You can drop it into existing standard mounting footprints, but verify your port and rod thread dimensions.
