About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-30S
The AirTAC SAIJ32X170-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 140-170 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance. The integrated magnet supports position sensing, while the extruded aluminum barrel maintains standard dimensions.
You can fine-tune the retract end-position at commissioning without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for dead-load holding, consider an external rod lock or the SAIL series. This 32 mm bore model uses a G1/8 port, an M10x1.25 rod thread, and operates at speeds of 30-800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-30S Is Used
Product Changeovers
Dial in the 140-170 mm travel window during format changes on packaging lines without replacing hardware.
End-Stop Calibration
Fine-tune the retract position during machine commissioning to achieve precise sensor triggering.
Variable Assembly Stops
Adjust the stroke on the fly to accommodate different part lengths in automated assembly cells.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-30S the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires precise end-position tuning within a 140-170 mm window. If the job demands greater thrust, stepping up to the 40 mm bore provides 628 N of push force at 0.5 MPa. The adjustable stroke is ideal for machine setups requiring product changeovers, whereas a fixed SAI cylinder is better for static, repeatable stops.
As a dimensionally interchangeable ISO 15552 profile cylinder, this model matches standard mounting footprints. It accepts PT tapered port threads and works with AirTAC CMSE reed and DMSE electronic sensors via its -S magnet. Available mountings include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the stroke is under 300 mm, side-load risks are minimal, but external guidance is still recommended for heavy lateral loads.

- ✓ 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 SAIJ32BX170-30S FAQ
The rear adjuster allows you to trim the nominal 170 mm stroke back by up to 30 mm, providing a usable travel window of 140 to 170 mm. It functions as a mechanical stop and does not lock the load without continuous air pressure.
At 0.5 MPa operating pressure, it generates 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
