About the Airtac SAI50 Standard Cylinder SAI50X240
The AirTAC SAI50X240 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 240mm stroke. It provides a push force of 982 N at 0.5 MPa, making it well-suited for medium-duty handling tasks. The extruded aluminum barrel design omits tie-rods, presenting a clean exterior that speeds up installation and maintenance.
This configuration utilizes a standard carbon steel piston rod and PT tapered port threading. Because it lacks an integrated magnet, it operates without position feedback unless externally retrofitted. For applications requiring end-of-stroke detection, the -S variant with CMSE or DMSE sensors would be required.

Where the Airtac SAI50 Standard Cylinder SAI50X240 Is Used
Package Sorting
Diverts packages on conveyors using the 982 N push force to reliably push items into sorting lanes at 0.5 MPa.
Clamp Fixtures
Secures workpieces on machining beds where the 240mm stroke accommodates varying part widths during clamping.
Pallet Loading
Positions products into pallet layers, utilizing the smooth pneumatic retraction to prevent damaging delicate goods.
Is the Airtac SAI50 Standard Cylinder SAI50X240 the Right Cylinder?
If your application requires less energy, stepping down to a 40mm bore yields 628 N at 0.5 MPa, while a 63mm bore offers 1559 N for heavier loads. At 240mm, this stroke is fully supported within the standard range, though any stroke reaching 300mm or more requires careful attention to side-load management to prevent rod-bearing bending.
The SAI50X240 is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders. It utilizes a G1/4 port and supports FA, LB, and TC mounting accessories. Note that this standard cylinder does not hold its load upon air loss; for fail-safe holding, 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.
Airtac SAI50 Standard Cylinder SAI50X240 FAQ
