About the Airtac SAI40 Standard Air Cylinder SAI40AX170S
The AirTAC SAI40X170-S is a double-acting ISO 15552 profile cylinder engineered for mid-range automation tasks. Delivering a push force of 879 N at 0.7 MPa, this 40 mm bore unit paired with a 170 mm stroke fits perfectly into compact assembly lines. The extruded aluminum barrel eliminates traditional tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
Configured here with a SUS420J2 stainless steel rod (material code A), it offers superior corrosion and scratch resistance compared to standard carbon steel, extending seal life in harsher environments. The integrated magnet (-S) allows seamless operation with CMSE or DMSE reed switches housed neatly within the dual sensor grooves on the barrel.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX170S Is Used
Component Clamping
Provides reliable 879 N clamping force to secure aluminum housings during CNC machining operations.
Package Diverting
Actuates routing gates on packaging lines, utilizing the 170 mm stroke to redirect products smoothly.
Press Ejection
Pushes finished stamped parts out of small pneumatic presses, benefiting from the scratch-resistant SUS420J2 rod.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX170S the Right Cylinder?
Choose this 40 mm bore when a 32 mm cylinder lacks sufficient thrust (563 N at 0.7 MPa) and you need the extra 316 N of push power without jumping to the bulkier 50 mm profile. The 170 mm stroke provides ample extension for indexing and clamping, though for any application exceeding 300 mm you must evaluate side-load conditions. Because this is a standard double-acting cylinder, it cannot hold a load if air pressure drops; use an external pilot-operated check valve or the SAIL variant if position holding is required.
This model ensures a true dimensionally interchangeable direct replacement per ISO 15552 standards. To match this exact configuration, specify the 40 mm bore, 170 mm stroke, PT tapered port thread (G1/4), your preferred mounting accessory like an FA flange, and the -S magnet option.
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.
