About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-40
The AirTAC SAIJ32X800-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 760-800mm usable travel window, letting you dial back the 800mm nominal stroke by up to 40mm during machine commissioning without adding external stops. It delivers a 402N push force at 0.5MPa, utilizing a 12mm rod with an M10x1.25 thread.
This variant uses a SUS420J2 stainless steel rod for improved corrosion resistance and PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount reed CMSE or solid-state DMSE switches directly. The rear screw acts as a travel stop, not a lock, so it cannot hold loads without live air.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-40 Is Used
Machine Commissioning
Fine-tune the exact retract position within the 760-800mm window during setup without swapping out the entire cylinder.
Product Changeover
Quickly adjust the end-stop by up to 40mm on a packaging line when handling slightly different product sizes.
Long-Travel Conveying
Manage long 800mm travel pushes while using the rear screw to dial in the precise stopping point for delicate items.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-40 the Right Cylinder?
Choose this 32mm bore when you need precise end-position tuning over a long travel distance. If your application requires higher thrust, stepping up to the 40mm bore yields 628N push force at 0.5MPa. The 40mm adjustment range is perfect for product changeovers, whereas a fixed-stroke SAI cylinder locks you into one exact dimension.
For replacing an ISO 15552 cylinder, match the 32mm bore, 800mm stroke, PT port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 800mm, the 12mm rod is susceptible to side-loading; always use an external guide to prevent binding. For load-holding without live pressure, select a SAIL or BSAI cylinder instead.
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 SAIJ32AX800-40 FAQ
At 0.5MPa operating pressure, it provides 402N of push force and 345N of pull force. The maximum thrust is 82kgf at 1.0MPa.
The rear adjuster screw lets you shorten the effective travel from 800mm down to 760mm. This creates a 40mm adjustable window for fine-tuning the end position without changing the physical cylinder.
