About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-75S
The AirTAC SAIJ32X220-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 220 mm travel back by up to 75 mm. This creates a highly flexible 145-220 mm usable stroke window, letting you dial in the exact end position at commissioning without swapping out the cylinder or adding external stops.
Because this configuration includes the -S magnet option, it directly supports AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side sensor grooves of the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to set the travel end alongside the standard air cushions, meaning it will not hold a load dynamically without live air pressure. For applications requiring true load-holding without continuous pressure, a related SAIL or BSAI series would be required.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-75S Is Used
Product Changeovers
Fine-tune the 145-220 mm travel window during line changeovers to accommodate different product sizes without physically swapping the cylinder.
End-Position Tuning
Use the 75 mm rear adjuster to dial in the exact retract stop during machine setup, eliminating the need for external mechanical stops.
Sensor-Driven Automation
Leverage the -S magnet and dual sensor grooves to mount CMSE or DMSE switches for precise position verification in automated assembly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-75S the Right Cylinder?
Choose this 32 mm bore if your application requires precise positioning within a 145-220 mm window, as the 75 mm adjustment range provides exceptional flexibility for product changeovers. The integrated SUS304 stainless steel rod handles minor side loads well, but because the 220 mm stroke is relatively long for a 32 mm bore, you should use an external guide rail to prevent binding and premature seal wear.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 220 mm nominal stroke, PT port thread, and the reduced SAIJ mounting set, which includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options (omitting FB, CA, CB, and CR). The -S magnet ensures compatibility with AirTAC CMSE and DMSE switches for automated position feedback.

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 Adjustable Cylinder SAIJ32 SAIJ32BX220-75S FAQ
The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 75 mm from the 220 mm nominal length, providing a usable travel window of 145-220 mm. It sets the end position but does not lock the load without live air pressure.
