About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-50
The AirTAC SAIJ32X275-50 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 225-275 mm usable travel window, allowing you to dial back the 275 mm nominal stroke by up to 50 mm.
This unit uses a SUS420J2 stainless steel rod (option A) for superior corrosion resistance compared to standard carbon steel. It features PT tapered port threads (G1/8) and includes variable air cushions at both ends measuring 27 mm. The extruded aluminum barrel integrates dual-side sensor grooves, though this specific SKU omits the magnet, requiring a solid-state DMSE or reed CMSE switch to be added separately if position sensing is needed later.

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 SAIJ32AX275-50 Is Used
Machine Changeover
Dial in the 225-275 mm travel window during product size changes without adding external stopper blocks to your frame.
End-Position Tuning
Fine-tune the retract stroke at commissioning using the 50 mm rear adjuster to perfect machine timing.
Assembly Station Setup
Set precise variable end-stops for delicate pressing or clamping tasks within the 32 mm bore force range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-50 the Right Cylinder?
Choose this 32 mm bore adjustable model when your machine setup requires fine end-position tuning during commissioning or product changeover without swapping out the entire cylinder. The rear adjuster acts strictly as a mechanical stop for deceleration and positioning, not a lock; a plain SAIJ will not hold a load without live air pressure, so for fail-safe load holding you should look to the SAIL or BSAI series. As a dimensionally interchangeable ISO 15552 cylinder, it matches standard SAI footprint dimensions and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) while omitting FB, CA, CB, and CR brackets.
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 SAIJ32AX275-50 FAQ
The rear adjuster screw lets you shorten the effective travel from the 275 mm nominal stroke down to a minimum of 225 mm. This creates a 50 mm adjustable window for fine-tuning the end position at commissioning without replacing the cylinder.
