About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX120-10
The AirTAC SAIJ32X120-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel. With a 120 mm nominal stroke and a 10 mm adjustment range, it provides a usable travel window of 110-120 mm for precise end-position tuning during commissioning.
This model uses PT tapered G1/8 ports and variable air cushions at both ends to decelerate the load. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. The rear adjuster acts purely as a travel stop to set the retract position and does not hold the load without live air pressure.

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 SAIJ32AX120-10 Is Used
End-Position Tuning
Dial in the exact 110-120 mm retract position during machine commissioning to perfect a pick-and-place motion without adding external stopper blocks.
Product Changeover
Quickly adjust the stroke by up to 10 mm on a packaging line when switching to a slightly different product size, saving changeover time.
Assembly Clamping
Apply 402 N of clamping force at 0.5 MPa while fine-tuning the exact clamping depth to prevent part deformation during assembly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX120-10 the Right Cylinder?
If your setup needs less force, stepping down is not an option in this series, but if you require significantly more thrust, consider the 40 mm bore which provides 628 N. An adjustable stroke is preferred over a fixed SAI cylinder when you need to fine-tune the retract position during machine setup or product changeovers.
For ISO 15552 replacement, match the 32 mm bore, 120 mm stroke, 10 mm adjustment, PT port thread, and your required mounting style. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because this is a 120 mm stroke, side loads are minimal, but always ensure the rod end is guided to prevent binding. For load-holding without live pressure, use an external rod lock or pilot-operated check valve, as the adjuster is not a brake.
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 SAIJ32AX120-10 FAQ
The rear adjuster screw lets you shorten the nominal 120 mm stroke by up to 10 mm, giving a usable travel window of 110-120 mm. This allows you to set the exact retract end-position during commissioning without changing the cylinder.
No, the rear adjuster is a travel stop, not a lock. The cylinder and its air cushions cannot hold a load without live air pressure. For fail-safe load holding, you need an external rod lock, a pilot-operated check valve, or an AirTAC SAIL or BSAI cylinder.
