About the Airtac SAI50 Standard Cylinder SAI50X325S
The AirTAC SAI50X325-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 325mm stroke. It generates 982N of push force and 825N of pull force at 0.5 MPa, making it a robust choice for mid-range automation tasks.
This variant includes a standard carbon steel piston rod and a built-in magnet for position detection. The extruded aluminum barrel features sensor grooves on both sides, allowing seamless integration with CMSE or DMSE reed switches. Port threads are PT (tapered), and adjustable air cushions at both ends ensure smooth deceleration.

Where the Airtac SAI50 Standard Cylinder SAI50X325S Is Used
Package Diverting
Ideal for pushing packages on conveyors where the 325mm stroke provides the reach needed to clear product lanes.
Component Staging
Moves workpieces into machining centers with precise 982N force and smooth end-of-stroke cushioning.
Pallet Positioning
Aligns lightweight pallets or totes at transfer stations using integrated DMSE sensor feedback.
Is the Airtac SAI50 Standard Cylinder SAI50X325S the Right Cylinder?
If your application requires less force, stepping down to the 40mm bore yields 628N at 0.5 MPa. Conversely, upgrading to the 63mm bore provides 1559N for heavier loads. Because this 325mm stroke exceeds 300mm, side loads can cause rod-bearing bending; utilizing an external guide rail or a guided cylinder is recommended to prevent premature wear.
For ISO 15552 interchangeability, match the 50mm bore, 325mm stroke, G1/4 port, and desired mounting accessory like the FA flange or LB foot. Remember that this standard cylinder relies on live air pressure to hold position; if exhaust or valve centering causes drift, consider the SAIL lock variant.
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 SAI50X325S FAQ
