About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X170-30
The AirTAC SAIJ32X170-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 140-170 mm usable travel window, allowing you to trim the nominal 170 mm stroke by up to 30 mm during commissioning without swapping the cylinder or adding external stops. In the 32 mm bore class, it generates 402 N of push force and 345 N of pull force at 0.5 MPa.
This model features a carbon steel piston rod with an M10x1.25 thread and a PT tapered port. It includes variable air cushions at both ends to decelerate the load smoothly. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for position holding, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X170-30 Is Used
Machine Changeovers
Dial in the 140-170 mm travel window during product size changes to set new retract endpoints without physically swapping cylinders.
End-Position Tuning
Fine-tune the final retract position at commissioning to achieve exact alignment, compensating for mechanical tolerance stack-up.
Light Assembly Automation
Drive small 402 N push-force operations where the rear stopper allows precise positioning of light tooling without external stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X170-30 the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires 402 N of push force at 0.5 MPa but demands precise end-position tuning. If your setup requires higher thrust, stepping up to the 40 mm bore yields 628 N of push force. The adjustable 140-170 mm travel window is ideal for product changeovers, whereas a fixed-stroke SAI cylinder is better suited for applications with rigid, unchanging end stops.
To match this ISO 15552 interchangeable cylinder exactly, confirm the 32 mm bore, 170 mm nominal stroke, 30 mm adjustment range, PT port thread, and carbon steel rod material. Because it lacks a magnet (-S), it will not work with CMSE or DMSE sensors. For any stroke at or above 300 mm, an external guide is recommended to prevent excessive side loading, though this 170 mm stroke is generally well-supported by the M10x1.25 rod.
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 SAIJ32X170-30 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw lets you shorten the effective stroke by up to 30 mm, creating a 140-170 mm usable travel window. It functions as a mechanical stop to set the end position and is not a locking device.
