About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-75
The AirTAC SAIJ32X260-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 402N of push force and 345N of pull force at 0.5 MPa, utilizing a 12mm piston rod with an M10x1.25 thread. By integrating a rear stopper screw, this model provides a usable travel window of 185 to 260 mm, allowing you to dial back the nominal 260 mm stroke by up to 75 mm during commissioning.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops when fine-tuning end positions. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the magnet, meaning CMSE or DMSE electronic sensors cannot be used for position detection. The rod is constructed from SUS420J2 stainless steel (code A) for enhanced corrosion resistance, and the cylinder supports PT tapered port threads.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-75 Is Used
Product Changeover
Quickly adjust the retract end-position by up to 75mm when switching between product sizes on a packaging line, without replacing the cylinder.
Machine Setup
Fine-tune the 185-260mm travel window during initial commissioning to achieve precise end-of-stroke positioning without external stops.
Variable End Stops
Dial in the exact stopping point for diverter arms or gating mechanisms on a conveyor, adapting to varying package dimensions on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-75 the Right Cylinder?
Choose this 32mm bore adjustable cylinder when your setup requires variable end-stops or frequent product changeovers, stepping down from a 40mm bore (which provides 628N push force at 0.5 MPa) if your application demands lower force and finer tuning. The rear adjuster acts solely as a travel stop to set the retract position; it does not hold the load without live air pressure. For load-holding requirements without continuous air supply, consider an AirTAC SAIL or BSAI cylinder, or use an external pilot-operated check valve.
To match this ISO 15552 cylinder for replacement, verify the 32mm bore, 260mm stroke, 75mm adjustment range, PT G1/8 port, and the absence of a magnet. The SAIJ mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Since the 260mm stroke exceeds 300mm only marginally but still represents extended travel, ensure adequate external guiding to prevent excessive side-loading on the rod.
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 SAIJ32AX260-75 FAQ
At an operating pressure of 0.5 MPa, 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 screw allows you to shorten the effective stroke from the nominal 260mm down to a minimum of 185mm, giving a 75mm adjustable window. The adjuster acts as a mechanical stop and does not lock the load without live air pressure.
