About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-30
The AirTAC SAIJ32X290-30 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 290 mm stroke that can be dialed back by up to 30 mm, yielding a precise 260-290 mm usable travel window. The extruded aluminum barrel features sensor grooves on both sides, though this unit lacks the -S magnet option for CMSE or DMSE switches.
This model features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance compared to standard carbon steel. It uses PT tapered port threads (G1/8) and includes adjustable air cushions at both ends to decelerate the moving load. The rear stopper acts purely as a travel end setter, not a lock, so continuous air pressure is required to hold the load in place.

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 SAIJ32AX290-30 Is Used
Machine Setup Calibration
Dial in the exact 260-290 mm retract position during initial commissioning to perfectly align a pick-and-place head without machining custom spacers.
Product Size Changeover
Quickly adjust the end-stop by up to 30 mm on a packaging line when switching between different product lengths, minimizing downtime.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-30 the Right Cylinder?
An adjustable-stroke cylinder is selected over a fixed-stroke SAI when you need to fine-tune the retract end position during commissioning or product changeover without adding external stops. For load-holding without live air pressure, this cylinder is insufficient since the adjuster is only a stop—consider an SAIL or BSAI model instead.
When matching this ISO 15552 cylinder for a replacement, verify the 290 mm stroke, 30 mm adjustment range, PT port thread, and mounting style. SAIJ supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 290 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 rod thread have limited side-load capacity; always use an external guide rail to prevent rod binding and premature seal wear.
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 SAIJ32AX290-30 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm, creating a 260-290 mm travel window. It functions as a mechanical stop to set the end position and does not lock the load without live air pressure.
