About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-40
The AirTAC SAIJ32X425-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 385 to 425 mm, allowing you to dial back the 425 mm nominal stroke by up to 40 mm during machine commissioning. In the 32 mm bore class, it generates 563 N of push force and 345 N of pull force at 0.5 MPa, utilizing a 12 mm carbon steel rod with an M10x1.25 thread.
This variant incorporates a SUS304 stainless steel rod (option B) for superior corrosion resistance in humid or washdown environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement, and the standard PT tapered port threads ensure a tight, reliable pneumatic connection.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-40 Is Used
Machine Changeover
Fine-tune the 385-425 mm travel window during product size changes on a packaging line without physically swapping out the cylinder.
Variable End-Stop Positioning
Dial in the exact retract position during initial machine commissioning to accommodate varying part dimensions on the fly.
Washdown Actuation
Leverage the SUS304 stainless steel rod for reliable actuation in food processing or humid environments requiring strict corrosion resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-40 the Right Cylinder?
Select this 32 mm bore unit when an application requires precise end-position tuning without adding external physical stops. If your process needs higher force, stepping up to the 40 mm bore yields 879 N of push at 0.7 MPa. The rear adjuster on this SAIJ model acts solely as a travel stop to set deceleration; it does not lock the load. For true load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder.
Because the 425 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 thread will not support high side loads alone; an external guide is recommended to prevent rod binding. This cylinder uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR. It is dimensionally interchangeable per ISO 15552, operating at speeds between 30 and 800 mm/s.

- ✓ 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 SAIJ32BX425-40 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 40 mm, creating a usable travel window of 385 to 425 mm. It acts as a mechanical stop to tune the end position, but it does not hold the load without live air pressure.
At 0.7 MPa, it provides 563 N of push force and 484 N of pull force. The standard speed range for this 32 mm bore size is 30 to 800 mm/s.
