About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-50S
The AirTAC SAIJ32X275-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability allows precise end-position tuning during commissioning without swapping out the cylinder.
This specific SKU is configured with a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and fluid control is managed via a PT tapered G1/8 port.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ32AX275-50S Is Used
Machine Changeover
Dial in the 225-275 mm travel window during product size changes without physically replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract stroke at commissioning to achieve exact positioning, compensating for mechanical tolerances in the fixture.
Variable End Stops
Sort or push items on a line where the required extension distance occasionally shifts by up to 50 mm between runs.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-50S the Right Cylinder?
If your setup demands less force, stepping down is not an option in this size range, but stepping up to a 40 mm bore provides 879 N at 0.7 MPa. The adjustable stroke is ideal for product changeovers on a line, whereas a fixed SAI cylinder is better for rigid, unchanging endpoints. For exact ISO 15552 replacement matching, verify the 275 mm stroke, 50 mm adjustment, PT port, and mounting style. Because the stroke is 275 mm, ensure external guides are used to prevent excessive side-loading on the 12 mm rod.
The rear adjuster acts strictly as a travel stop and works alongside the standard air cushion to decelerate the load. It does not hold the load without live air pressure; for true load-holding without continuous air, consider an AirTAC SAIL or BSAI cylinder.
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 Adjustable Cylinder SAIJ32 SAIJ32AX275-50S FAQ
The rear adjusting screw allows you to shorten the effective stroke by up to 50 mm. This creates a usable travel window of 225 to 275 mm, letting you set the exact retract end-position without changing the cylinder.
At a 0.7 MPa operating pressure, the push force is 563 N and the pull force is 345 N.
