About the Airtac SAI50 Standard Cylinder SAI50X175S
The AirTAC SAI50X175-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 175mm stroke. It provides 982N of push force and 825N of pull force at 0.5MPa, making it well-suited for mid-range automation tasks. The extruded aluminum barrel design omits tie rods for a cleaner exterior.
This specific variant includes a built-in magnet for position detection and is equipped with a standard carbon steel piston rod. It supports CMSE and DMSE sensor switches that fit directly into the dual grooves on the barrel. For higher temperature environments up to 70C, the standard TPU seals can be swapped for Viton (H) or NBR (N) alternatives.

Where the Airtac SAI50 Standard Cylinder SAI50X175S Is Used
Material Handling
Drives package diverters and sorting gates on conveyor lines requiring 982N of push force at 0.5MPa.
Assembly Jigs
Clamps workpieces securely during machining or assembly operations using the 175mm stroke length.
Packaging Equipment
Actuates folding arms and sealing presses in automated packaging machinery with reliable magnetic feedback.
Is the Airtac SAI50 Standard Cylinder SAI50X175S the Right Cylinder?
If your application requires less force, stepping down to a 40mm bore drops the 0.5MPa push force to 628N. Conversely, upgrading to a 63mm bore yields 1559N. At 175mm stroke, side-load stress on the rod bearing is minimal, but always verify your mounting orientation. This model uses a PT tapered port thread and pairs with FA or FB flange accessories for secure ISO 15552 mounting.
Note that the standard adjustable air cushions only decelerate the piston at stroke end; they do not hold a load. If pressure is lost, the rod will drift. For suspended loads requiring fail-safe holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) variant instead of relying on a standard cylinder.
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 SAI50X175S FAQ
At 0.5MPa, the SAI50X175-S generates 982N of push force and 825N of pull force. If you increase the operating pressure to 0.7MPa, the push force rises to 1374N.
Yes, the SAI50X175-S is dimensionally interchangeable per ISO 15552 standards. It serves as a direct replacement for other ISO 15552 profile cylinders, matching standard mounting interfaces and G1/4 ports.
