About the Airtac SAI63 Standard Cylinder SAI63X225
The AirTAC SAI63X225 is a double-acting ISO 15552 profile cylinder built with a tie-rod-less extruded aluminum barrel. It delivers a push force of 1559 N and a pull force of 1402 N at 0.5 MPa. The 225 mm stroke provides an extended travel distance that bridges the gap between standard 200 mm and 250 mm options, making it highly versatile for mid-range automation tasks.
This model features a standard carbon steel piston rod and a PT (tapered) port thread. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE switches, though a magnet (-S suffix) must be specified if position sensing is required. For operations involving higher thermal loads, the standard TPU seals can be swapped for Viton (H) variants.

Where the Airtac SAI63 Standard Cylinder SAI63X225 Is Used
Material Handling
Extends 225 mm to push mid-weight pallets or divert packages along sorting lines with 1559 N of linear thrust.
Assembly Automation
Drives clamping fixtures and press-fit mechanisms where a longer mid-range stroke is required for part clearance.
Packaging Equipment
Actuates folding arms and sealing heads over larger carton profiles using reliable double-acting pneumatic power.
Is the Airtac SAI63 Standard Cylinder SAI63X225 the Right Cylinder?
At 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force. If your application requires less force, stepping down to a 50 mm bore yields 982 N, while upgrading to an 80 mm bore provides 2513 N for heavier payloads. Because the 225 mm stroke is under the 300 mm threshold, side-load stress on the rod bearing is moderate, but external guides are still recommended if the load is not perfectly axial.
As a dimensionally interchangeable ISO 15552 profile cylinder, it serves as a direct replacement for other standard ISO 15552 cylinders. To mount this unit, you can utilize standard accessories like FA/FB flanges or TC trunnions. Note that the adjustable air cushions at both ends decelerate the piston near stroke end but do not lock the load; if position holding without air pressure is needed, 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.
