About the Airtac SAI40 Standard Air Cylinder SAI40AX145S
The AirTAC SAI40X145-S is a double-acting ISO 15552 profile cylinder engineered for tasks requiring a 145 mm stroke. It delivers a push force of 628 N at 0.5 MPa and 879 N at 0.7 MPa, making it well-suited for moderate-duty positioning and clamping chores.
This specific configuration incorporates a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance over standard carbon steel. Because it includes the -S magnet option, the extruded aluminum barrel's dual sensor grooves are fully utilized when pairing with CMSE or DMSE switches for precise end-of-stroke detection.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX145S Is Used
Component Clamping
Secures aluminum or composite workpieces during CNC machining, using the 879 N push force at 0.7 MPa to hold parts firmly against fixture stops.
Package Diverting
Actuates a 145 mm stroke diverting arm to route small to medium packages between conveyor lanes in material handling lines.
Gate Control
Operates lightweight access gates or machine guard doors, where the mid-range thrust and compact 40 mm profile provide reliable movement.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX145S the Right Cylinder?
If your application needs less thrust, the adjacent 32 mm bore provides 563 N at 0.7 MPa, while stepping up to a 50 mm bore yields 1374 N at 0.7 MPa for heavier loads. At 145 mm, this stroke is fully supported by the standard range, keeping lead times short.
This model uses PT tapered port threads and a G1/4 connection. As a true ISO 15552 profile cylinder, it drops into existing mounting interfaces using standard FA/FB flanges or LB foot brackets. Note that the adjustable air cushions only decelerate the piston near the end caps; they do not lock the load. If pressure is lost, the rod will drift. For position holding without live air, consider the SAIL variant with an air-released lock or an external pilot-operated check valve.
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 SAI40 Standard Air Cylinder SAI40AX145S FAQ
