About the Airtac SAI40 Standard Air Cylinder SAI40X950SN
The AirTAC SAI40X950-S is a double-acting ISO 15552 profile cylinder engineered for extended reach operations. It provides a push force of 879 N at 0.7 MPa, making it well-suited for moving moderate loads across long linear distances. This specific configuration includes a piston magnet for proximity sensing.
Equipped with standard carbon steel rod material and durable NBR seals, this unit handles operating pressures from 0.15-1.0 MPa. The barrel features integrated sensor grooves on both sides, allowing straightforward mounting of CMSE or DMSE reed switches. Fluid must be filtered air, and the PT port thread type ensures a secure, tapered pneumatic connection.

Where the Airtac SAI40 Standard Air Cylinder SAI40X950SN Is Used
Long-Stroke Material Transfer
Pushes workpieces between machining stations over a 950 mm gap, utilizing the 879 N force to overcome friction on conveyor rollers.
High-Bay Ejection
Actuates a 950 mm ejection arm to push cartons from storage racks, relying on the integrated magnet for precise position feedback.
Extended Reach Gating
Drives a diverter gate over a wide conveyor path, where the NBR seals ensure reliable operation across millions of cycles at standard temperatures.
Is the Airtac SAI40 Standard Air Cylinder SAI40X950SN the Right Cylinder?
Selecting this 40 mm bore over the smaller 32 mm variant upgrades your push force from 563 N to 879 N at 0.7 MPa. If your application requires even greater thrust, stepping up to the 50 mm bore yields 1374 N. Because this model features a 950 mm stroke, the extended rod is highly susceptible to bending under side loads. Employ an external guide rail or utilize a dedicated guided cylinder to prevent premature rod-bearing wear.
This unit is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other standard profile cylinders with a 40 mm bore, 950 mm stroke, G1/4 port, and matching mounting accessories like FA flanges or LB foot brackets. The included magnet (-S) enables precise end-of-stroke detection. Note that standard air cushions only decelerate the piston near stroke ends; if the system loses air pressure, the load will drift. For position holding without live pressure, consider 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.
