About the Airtac SAI63 Standard Cylinder SAI63BX225S
The AirTAC SAI63X225-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 225 mm stroke falls outside the standard incremental lengths, making it a tailored solution for applications requiring exact intermediate travel distances.
Built with a SUS304 stainless steel piston rod (material code B), this unit provides superior corrosion resistance for harsh or washdown environments. It includes a built-in magnet for position sensing via CMSE or DMSE switches mounted in the dual-side sensor grooves, and features PT tapered port threads.

Where the Airtac SAI63 Standard Cylinder SAI63BX225S Is Used
Intermediate Travel Clamping
Provides exact 225 mm extension for clamping irregularly sized workpieces in automated machining centers where standard strokes fall short.
Stainless Diverter Arm
The SUS304 rod and 1559 N thrust make it ideal for actuating heavy sorting gates in food processing lines requiring frequent washdowns.
Press Ejection System
Uses the integrated magnet and dual sensor grooves to confirm retraction before cycling, safely ejecting formed parts from hydraulic presses.
Is the Airtac SAI63 Standard Cylinder SAI63BX225S the Right Cylinder?
Selecting this 63 mm bore provides a substantial step up in thrust over the 50 mm variant, which yields 982 N at 0.5 MPa, without requiring the physical footprint of the 80 mm model. Because the 225 mm stroke is a non-standard made-to-order length, ensure your machine cycle timing accommodates the 30-800 mm/s speed range.
With a stroke exceeding 200 mm, side loads can induce rod-bearing bending; utilize an external guide rail or a guided cylinder to prevent premature wear. If the mechanism must maintain its position after a loss of supply pressure, pair this cylinder with an external pilot-operated check valve or transition to the SAIL locking variant, as standard air cushions only decelerate the piston and do not brake or hold loads. This unit is dimensionally interchangeable per ISO 15552, accepting standard mounting accessories like FA flanges or TC trunnions alongside PT G3/8 ports.
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 SAI63 Standard Cylinder SAI63BX225S FAQ
At a 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X225-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts using standard accessories like LB foot brackets or TC trunnions, matching the 63 mm bore and 225 mm stroke dimensions.
