About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-20
The AirTAC SAIJ32X115-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 115 mm travel by up to 20 mm for a precise 95-115 mm usable window. The unit features a SUS420J2 stainless steel rod and PT tapered port threads.
Because the adjuster acts as a mechanical stop at the retract end, you can fine-tune the end position during commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration ships without a magnet. The mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets.

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 SAIJ32AX115-20 Is Used
Machine Setup & Changeover
Dial in the exact 95 to 115 mm retract position during product changeover without machining new hard stops or replacing the entire actuator.
Variable End Stops
Provide adjustable physical endpoints for lightweight conveyor diverters or sorting gates that handle varying package dimensions on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-20 the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring a variable end stop, whereas a fixed SAI cylinder is better for rigid, unchanging travel. Keep in mind the rear adjuster only sets the travel end and does not hold the load without live air—use a SAIL or BSAI cylinder for true locking needs. For an exact ISO 15552 replacement, match the 32 mm bore, 115 mm stroke, 20 mm adjustment, PT port threads, and SUS420J2 rod material.
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 SAIJ32AX115-20 FAQ
At 0.9 MPa, the push force increases to 724 N.
The SAIJ32X115-20 has a nominal 115 mm stroke with a 20 mm rear adjuster, creating a usable travel window of 95 to 115 mm. The rear screw acts as a mechanical stop to trim the travel end, but it is not a lock and will not hold the load without continuous air pressure.
