About the Airtac SAI50 Standard Cylinder SAI50X225
The AirTAC SAI50X225 is a double-acting ISO 15552 profile cylinder offering a push force of 982 N at 0.5 MPa and a pull force of 825 N. Its 225 mm stroke provides the extended travel needed for mid-range material handling and automated clamping tasks. Because it uses an extruded aluminum barrel, it avoids the bulk of older tie-rod designs while maintaining exact ISO 15552 mounting interchangeability.
This specific configuration features a robust carbon steel piston rod and PT tapered port threads. The barrel includes integrated sensor grooves on both sides, allowing you to mount position switches along the travel path if needed. For higher temperature environments, the standard TPU seals can be swapped for Viton (H) variants.

Where the Airtac SAI50 Standard Cylinder SAI50X225 Is Used
Package Handling
Pushes or diverts medium-weight packages along conveyor lines using the 982 N push force available at 0.5 MPa.
Automated Clamping
Secures workpieces during machining or assembly operations, utilizing the 225 mm stroke to accommodate varying part sizes.
Palletizing
Extends to position or lift corrugated containers in end-of-line palletizing cells, relying on the ISO 15552 mounting interface for rigid attachment.
Is the Airtac SAI50 Standard Cylinder SAI50X225 the Right Cylinder?
If your application requires less force, stepping down to a 40 mm bore yields 628 N of push force at 0.5 MPa. Conversely, moving up to a 63 mm bore provides 1559 N. At 225 mm of travel, side loads can exert leverage on the rod bearing; utilizing an external guide rail or a guided cylinder helps prevent premature wear.
This SAI50X225 is a direct replacement for any ISO 15552 cylinder with a 50 mm bore, 225 mm stroke, and G1/4 port. It uses standard FA/FB flanges or TC trunnion mounts. Remember that standard air cushions only decelerate the piston at stroke end; if you need to hold a load vertically without air pressure, select the SAIL locking variant or an external rod lock.
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.
