About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX120-50
The AirTAC SAIJ32X120-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the 120 mm nominal stroke by up to 50 mm. This creates a highly flexible 70-120 mm usable travel window, enabling precise end-position tuning at commissioning without swapping out the cylinder or adding external stops.
This model features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for position sensing. The rear adjustment screw acts purely as a travel stop for end-position deceleration and setup; it does not lock or hold the load without continuous 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 SAIJ32AX120-50 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance within the 70-120 mm window during machine commissioning to perfect product ejection without physical modifications.
Product Changeover
Quickly readjust the stroke length on automated lines when switching between different product sizes, minimizing downtime and avoiding external stop hardware.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX120-50 the Right Cylinder?
The rear adjuster allows you to fine-tune the retract position on the fly, a major advantage over a fixed-stroke SAI cylinder. Because the rear screw is a stop and not a lock, use a SAIL or BSAI cylinder if you need true load-holding without live air. As a dimensionally interchangeable ISO 15552 cylinder, match the replacement by confirming the 32 mm bore, 120 mm stroke, 50 mm adjustment, PT port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ32AX120-50 FAQ
It operates at a speed range of 30-800 mm/s, matching standard ISO 15552 performance.
A rear adjusting screw lets you shorten the 120 mm nominal stroke by up to 50 mm, creating a 70-120 mm usable travel window. The screw acts as a mechanical stop for fine-tuning end positions and does not hold the load without live air pressure.
