About the Airtac SAI50 Standard Cylinder SAI50X200
The AirTAC SAI50X200 is a double-acting profile cylinder featuring a 50mm bore and a 200mm stroke, designed to deliver 982N of push force at 0.5 MPa. Its extruded aluminum barrel fully conforms to ISO 15552 dimensional standards, ensuring a straightforward direct replacement for any existing ISO 15552 mounting interface.
This specific configuration includes a standard carbon steel piston rod and PT tapered port threads. Because it lacks a built-in magnet, it is optimized for purely mechanical actuation. For environments requiring high-temperature resistance up to +70C, Viton (H) seals can be specified instead of the standard TPU.

Where the Airtac SAI50 Standard Cylinder SAI50X200 Is Used
Package Diverting
Provides robust actuation for routing medium-weight parcels on sorting lines, utilizing the 200mm stroke to push items cleanly into downstream lanes.
Clamp Fixtures
Secures workpieces during machining operations, delivering 982N of push force at 0.5 MPa to hold components firmly against stops.
Gate Control
Automates the opening and closing of material flow gates, benefiting from the adjustable air cushions at both ends to prevent slamming.
Is the Airtac SAI50 Standard Cylinder SAI50X200 the Right Cylinder?
Selecting this 50mm bore offers a balanced middle ground between the 40mm bore (528N pull at 0.5 MPa) and the larger 63mm bore (1402N pull at 0.5 MPa). The 200mm stroke is well within the 1200mm maximum standard stroke for this bore size. Since the stroke is below 300mm, side-load stress on the rod bearing is minimal, though external guides are still recommended if lifting heavy off-center loads.
Keep in mind that the standard SAI50X200 relies on live air pressure to maintain its position; if pressure is lost, the piston will drift. If your application requires fail-safe load holding, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. Replacement matching requires a 50mm bore, 200mm stroke, PT port thread, and your chosen mounting accessory.
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 SAI50X200 FAQ
The SAI50X200 generates a push force of 982N at 0.5 MPa and 1374N at 0.7 MPa. The theoretical maximum force is 200 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per ISO 15552. You can replace other ISO 15552 profile cylinders of the same 50mm bore and 200mm stroke by matching the PT port thread and mounting accessories.
