About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-30
The AirTAC SAIJ32X115-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 30 mm. This creates an 85-115 mm usable stroke window, giving you exact end-position control at commissioning without needing to swap the barrel or bolt on external stops.
This variant features a SUS420J2 stainless steel piston rod for enhanced corrosion resistance and uses PT tapered port threading with a G1/8 air connection. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic solid-state switches (if a magnet is added later). Mounting options include the SAIJ subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32AX115-30 Is Used
Machine Changeover
Dial in the 85-115 mm travel window during product size transitions to set new end-stops rapidly without changing the cylinder.
Position Calibration
Fine-tune the retract end-position during commissioning to perfect the mechanical timing of a lower-force assembly process.
Adjustable Ejector
Vary the ejection stroke length on the fly to accommodate different part sizes on a compact handling line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-30 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your machine setup requires variable end-stops or frequent product-size changeovers, rather than a fixed-stroke SAI model. If your application needs greater thrust, stepping up to the 40 mm bore raises the 0.5 MPa push force to 628 N. The 12 mm rod and M10x1.25 thread handle moderate side loads, but for any stroke over 300 mm, always use an external guide to prevent binding.
When matching this cylinder for an ISO 15552 replacement, verify the 115 mm stroke, 30 mm adjustment range, PT G1/8 port, and the specific mounting footprint. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider the SAIL or BSAI series instead.
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 SAIJ32AX115-30 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw lets you shorten the nominal 115 mm stroke by up to 30 mm, creating an 85-115 mm usable travel window. The adjuster acts as a mechanical stop for end-position tuning and is not a lock, meaning it will not hold the load without live air pressure.
