About the Airtac SAI40 Standard Air Cylinder SAI40X50
The AirTAC SAI40X50 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 50mm stroke. It provides a push force of 628 N at 0.5 MPa, making it well-suited for compact, medium-duty handling tasks.
This model features a standard carbon steel piston rod and utilizes a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, allowing for straightforward position detection when paired with a compatible switch.

Where the Airtac SAI40 Standard Air Cylinder SAI40X50 Is Used
Package Diverting
Ideal for actuating diverters on packaging lines where 628 N of push force reliably moves light to medium cartons.
Small Part Clamping
Provides secure, stable clamping for machining or assembly fixtures within a compact 50mm stroke footprint.
Gate Control
Operates pneumatic gates and small machine doors requiring rapid, repeatable cycling within the 30-800 mm/s range.
Is the Airtac SAI40 Standard Air Cylinder SAI40X50 the Right Cylinder?
If your application requires less force, stepping down to the 32mm bore yields 402 N at 0.5 MPa; conversely, moving up to the 50mm bore provides 982 N. Because this 50mm stroke is relatively short, side-load stress on the rod bearing is minimal.
As a true ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders. Note that the adjustable air cushions only decelerate the piston at end-of-stroke; they do not hold a load. If static holding without air pressure is required, consider the SAIL or BSAI variants.
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.
