About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX210-75
The AirTAC SAIJ32X210-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 135 to 210 mm, allowing you to dial in the exact retract position without swapping physical components.
This configuration uses a SUS420J2 stainless steel piston rod for enhanced corrosion resistance compared to standard carbon steel. The barrel is extruded aluminum with sensor grooves on both sides, though this specific SKU omits the magnet, so external position sensing via CMSE or DMSE switches is not supported out of the box. The rear adjustment screw acts purely as a mechanical stop to set the travel end, working alongside the standard adjustable air cushions at both ends.

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 SAIJ32AX210-75 Is Used
Machine Changeover
Quickly reposition the retract end-stop within the 135-210 mm window when switching between product sizes on a packaging line.
End-Position Tuning
Fine-tune the exact resting position during commissioning without machining external spacers or replacing the cylinder.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX210-75 the Right Cylinder?
Choose this 32 mm bore adjustable model when your machine setup requires frequent end-position tuning or product-size changeovers, eliminating the need to bolt on external stops. Conversely, if you need to hold a load statically without live air pressure, a plain SAIJ is insufficient because the rear adjuster is a travel stop, not a lock; you would need to explore the SAIL or BSAI series instead.
For ISO 15552 replacement matching, verify the 32 mm bore, 210 mm nominal stroke, 75 mm adjustment range, PT tapered port thread, and the standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the nominal stroke is 210 mm, which is under the 300 mm threshold, side-load concerns are minimal, but the 12 mm rod and M10x1.25 thread mean you should still avoid heavy lateral loads.
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 SAIJ32AX210-75 FAQ
At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the effective stroke from its 210 mm nominal length down to as little as 135 mm. This creates a 135-210 mm travel window for precise end-position tuning without changing the cylinder.
