About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX40-10
The AirTAC SAIJ32X40-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 402N push force at 0.5 MPa and uses a PT tapered port. The built-in rear stopper allows you to fine-tune the end position, creating a usable travel window between 30 and 40 mm without adding external stops.
This compact 32mm bore model incorporates an SUS304 stainless steel rod for superior corrosion resistance. It offers variable air cushions at both ends to manage impact deceleration, though the adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX40-10 Is Used
End-Position Tuning
Dial in the exact retract distance within a 30-40mm window during machine commissioning to perfect pick-and-place alignment.
Product Size Changeover
Quickly adapt the stroke end-stop on a packaging line when handling slightly different package dimensions without swapping cylinders.
Precision Assembly
Apply precise 402N of push force at 0.5 MPa for pressing small components, using the rear screw to set the exact depth.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX40-10 the Right Cylinder?
Choose this 32mm bore cylinder when you need 402N of push force at 0.5 MPa and precise end-position tuning during commissioning. If your application requires less force, stepping down is not an option in this series, but stepping up to a 40mm bore yields 628N. The rear adjuster allows a 30-40mm travel window, which is ideal for variable product-size changeovers on a line.
To match this exact configuration for an ISO 15552 replacement, specify a 32mm bore, 40mm stroke, 10mm adjustment, PT port, and SUS304 (B) rod material. Note that SAIJ uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts. For position holding without live air, consider the SAIL or BSAI series instead.

- ✓ 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 SAIJ32BX40-10 FAQ
At a 0.5 MPa operating pressure, this 32mm bore cylinder provides a push force of 402N and a pull force of 345N. At 0.7 MPa, the push force increases to 563N.
The rear adjuster acts as a mechanical stopper that lets you shorten the effective travel from the nominal 40mm down to 30mm. This creates a 30-40mm adjustable window for fine-tuning the retract position at commissioning.
