About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX20-20
The AirTAC SAIJ32X20-20 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. With a nominal 20 mm stroke and a 20 mm adjustment screw, it provides a usable travel window of 0-20 mm, allowing you to dial in the exact end position at commissioning without adding external stops.
This bore size features a G1/8 PT port and M10x1.25 rod threading. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts strictly as a travel stop to fine-tune deceleration and end-position, not as a lock to 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 SAIJ32AX20-20 Is Used
Machine Changeover
Dial in the exact end-stop during product size changes on a packaging line without physically swapping cylinders.
End-Position Tuning
Fine-tune the 0-20 mm travel window at commissioning to perfect the seating of small components.
Short-Stroke Clamping
Provide adjustable clamping pressure on delicate workpieces where a fixed 20 mm stroke might overtravel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX20-20 the Right Cylinder?
The adjustable stroke is ideal for machine changeovers where the exact end-of-stroke position varies slightly, replacing the need to swap out a fixed-stroke SAI cylinder. For load-holding without live air, consider the SAIL or BSAI series, as the SAIJ adjuster is only a stop. When replacing an ISO 15552 cylinder, match the 32 mm bore, 20 mm stroke, 20 mm adjustment, G1/8 PT port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface.
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 SAIJ32AX20-20 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 20 mm. Since the nominal stroke is 20 mm, this gives you a usable travel window of 0-20 mm, allowing precise end-position tuning without changing the cylinder itself.
