About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-50
The AirTAC SAIJ32X115-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 65-115 mm usable travel window from its 115 mm nominal stroke. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This variant uses a SUS420J2 stainless steel rod for improved corrosion resistance and features PT tapered port threads on its G1/8 supply ports. The rear adjustment screw acts purely as a mechanical stop to trim the retract end-position without adding external stops. It is not a locking device and will not hold a 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 SAIJ32AX115-50 Is Used
Machine Setup Calibration
Dial in the exact 65 to 115 mm retract position during initial commissioning without machining custom spacer blocks.
Product Changeover Stops
Quickly adjust the end-of-stroke position on a packaging line when switching to a different product size.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-50 the Right Cylinder?
If your setup needs less force, there is no smaller ISO 15552 bore in this range; if you need significantly more power, stepping up to a 40 mm bore yields 628 N. The adjustable stroke is ideal for dialing in exact retract distances without swapping cylinders.
For ISO 15552 replacement matching, ensure you specify the 115 mm stroke, 50 mm adjustment range, PT port thread, and the SUS420J2 rod material. Since this is a 32 mm bore, it operates at speeds from 30-800 mm/s. Note that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If position holding is required without live air, consider an external pilot-operated check valve or the AirTAC SAIL series instead of relying on the adjuster.
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 SAIJ32AX115-50 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 115 mm nominal stroke by up to 50 mm, creating a 65-115 mm usable travel window. It only decelerates and sets the travel end; it does not lock or hold the load without continuous air pressure.
