About the Airtac SAI40 Standard Air Cylinder SAI40AX105S
The AirTAC SAI40X105-S is a double-acting ISO 15552 profile cylinder engineered for standardized automation. Delivering a push force of 879 N at 0.7 MPa, this 40 mm bore unit is paired with a 105 mm stroke to handle mid-range actuation tasks. The extruded aluminum barrel eliminates tie-rods, presenting a clean exterior that speeds up machine assembly.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid or mildly chemically washed environments. Equipped with a magnetic piston (-S), it supports direct mounting of CMSE or DMSE reed switches along the dual sensor grooves. Fluid ports utilize a PT tapered thread design, ensuring a robust, tight pneumatic connection.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX105S Is Used
Component Clamping
Provides reliable 879 N clamping force at 0.7 MPa for securing medium-sized metal parts during CNC machining or drilling operations.
Package Diverting
Actuates diverter arms on packaging lines, using the 105 mm stroke to push cartons between adjacent belts efficiently.
Gate Control
Operates safety gates and machine guarding doors, leveraging the corrosion-resistant SUS420J2 rod in factory environments.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX105S the Right Cylinder?
Select this 40 mm bore when an application requires stepping up from the 32 mm version (which provides 563 N push at 0.7 MPa) to handle increased payloads without jumping to the larger 50 mm profile. The 105 mm stroke offers a compact extension length well suited for shorter machine segments. Because the stroke is under 300 mm, side-load stress on the rod bearing remains minimal, though external guides are still recommended for heavy offset loads.
This model serves as a direct replacement for any ISO 15552 cylinder sharing the same 40 mm bore, 105 mm stroke, G1/4 port, and standard mounting accessories like FA flanges or LB foot brackets. Note that the standard adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If the machinery requires true position holding without live air pressure, integrate the SAIL locking variant 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.
