About the Airtac SAI100 Standard Air Cylinder SAI100AX70S
The AirTAC SAI100X70-S is a double-acting profile cylinder built to ISO 15552 dimensional standards, ensuring straightforward interchangeability with other compliant ISO 15552 actuators. Delivering a push force of 3927 N at 0.5 MPa, this 100 mm bore unit is tailored for high-thrust tasks over a compact 70 mm stroke.
This configuration features an SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance. The -S suffix denotes an integrated magnet, allowing seamless position detection using CMSE or DMSE sensor switches mounted in the extruded aluminum barrel's dual side grooves.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX70S Is Used
Heavy-Duty Stamping
Provides the robust 3927 N output at 0.5 MPa needed for short-stroke metal forming, riveting, and press-fit operations.
Pallet Diversion
Generates substantial force to push heavy pallets or workpieces onto secondary packaging lines without hesitation.
Component Seating
Ideal for securely driving large bearings or bushings into housings on automated assembly machinery.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX70S the Right Cylinder?
Choose this 100 mm bore when a 80 mm bore (2513 N at 0.5 MPa) lacks the necessary thrust for heavy lifting or pressing. The 70 mm stroke is optimal for short, powerful movements. For applications requiring position retention upon air loss, note that the standard SAI relies solely on adjustable air cushions for end-of-stroke deceleration and will drift without pressure; consider the SAIL locking variant for fail-safe hold.
To replace an existing actuator, match the 100 mm bore, 70 mm stroke, PT tapered G1/2 port, and mounting accessory (such as LB foot or TC trunnion). The -S magnet option is required if you are using CMSE/DMSE reed or solid-state switches.
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 SAI100AX70S FAQ
