About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-30S
The AirTAC SAIJ32X55-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 25 to 55 mm for precise end-position tuning. The PT tapered port threads ensure a tight, leak-free pneumatic connection.
Because the adjuster acts purely as a mechanical stop on the retract end, it cannot hold a load without continuous live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, allowing direct mounting of CMSE reed or DMSE electronic switches to track piston position accurately.

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 SAIJ32BX55-30S Is Used
Product Changeover
Dial in the 25-55 mm travel window rapidly during format changes on packaging lines without replacing the actuator.
End-Stop Tuning
Fine-tune the retract position at commissioning using the rear screw to perfect the picking motion of small parts.
Sensor Tracking
Leverage the -S magnet with DMSE electronic sensors to confirm the adjusted end position in automated test fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-30S the Right Cylinder?
If your setup needs less force, stepping down is not an option in the standard SAIJ range, but stepping up to a 40 mm bore yields 628 N. The rear screw allows you to dial in the exact 25-55 mm travel without swapping cylinders or adding external stops, unlike a fixed-stroke SAI. For load-holding without live pressure, consider an external rod lock or the SAIL series.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 55 mm nominal stroke, 30 mm adjustment, PT port thread, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
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 SAIJ32BX55-30S FAQ
The rear adjuster acts as a mechanical stop, letting you trim the nominal 55 mm stroke back by up to 30 mm, creating a 25-55 mm travel window. It sets the end position but does not lock the load without live air.
At 0.7 MPa, the push force increases to 563 N.
