About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-75
The AirTAC SAIJ32X375-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 375 mm travel by up to 75 mm. This yields a precise 300-375 mm usable window for commissioning without swapping hardware. It delivers 402 N of push force at 0.5 MPa and features a SUS304 stainless steel rod for superior corrosion resistance.
Because the 375 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 thread should be paired with an external guide to manage side loads. The rear adjuster acts purely as a travel stop and does not hold the load without live air. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-75 Is Used
Machine Changeover
Quickly fine-tune the 300-375 mm travel window during product size changes without physically swapping the cylinder or adding shims.
Variable End Stops
Ideal for diverter gates where the exact retract position needs occasional tweaking to handle different package sizes on the fly.
Setup Calibration
Dial in the exact end-of-stroke position during initial commissioning to perfect tooling alignment without external stopper blocks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-75 the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa with on-the-fly end-position tuning; if your application requires less force, dropping down adds flexibility, while stepping up to a 40 mm bore provides 628 N. The adjustable stroke is perfect for product changeovers, but note that the rear screw is a stop, not a lock. For load-holding without air pressure, consider an external rod lock or the SAIL series.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 375 mm stroke, 75 mm adjustment, PT tapered port, and the SUS304 rod material. As with any stroke of 300 mm or more, ensure your mounting setup includes external guidance to prevent binding.
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 SAIJ32BX375-75 FAQ
The rear adjuster screw lets you shorten the effective travel by up to 75 mm, providing a usable stroke window of 300-375 mm. It acts as a mechanical stop to fine-tune the retract position and does not lock the load.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
