About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-100
The AirTAC SAIJ32X260-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 160-260 mm usable travel window, allowing you to dial back the nominal 260 mm stroke by up to 100 mm during commissioning. Operating at 0.5 MPa, it delivers 402 N of push force and 345 N of pull force, making it suitable for lighter-duty tasks.
This specific configuration incorporates a SUS304 stainless steel rod for superior corrosion resistance and ships without a magnet. The barrel is extruded aluminum with sensor grooves on both sides, and the standard PT tapered port threads match the G1/8 air supply interface. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without adding external stops.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-100 Is Used
End-Position Tuning
Dial in the exact retract distance during machine commissioning without installing external physical stops.
Product Changeovers
Quickly adapt the travel window from 160 to 260 mm when running different sized components on the same line.
Light-Force Clamping
Apply up to 402 N of clamping force at 0.5 MPa, with the SUS304 rod resisting moisture in washdown areas.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-100 the Right Cylinder?
Choose this 32 mm bore when you need precise variable end-stops for product changeovers, stepping up from smaller frames or down from a 40 mm bore (which provides 628 N push force at 0.5 MPa). An adjustable stroke is preferred over a fixed SAI cylinder when a machine requires frequent end-position tuning without swapping the hardware. Because the 260 mm stroke approaches the upper limits for this bore size, ensure external guides support the load to prevent excessive side-loading on the 12 mm rod.
For ISO 15552 replacement matching, verify the 32 mm bore, 260 mm stroke, 100 mm adjustment range, PT G1/8 port, and the absence of a magnet. Remember that the rear adjuster and air cushions only decelerate the load; they do not hold it without live air. For fail-safe load holding, consider an external pilot-operated check valve or the AirTAC SAIL lock cylinder series.
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 SAIJ32BX260-100 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If higher force is needed, stepping up to a 40 mm bore yields 628 N of push force.
The rear adjuster acts as a mechanical stop that lets you shorten the 260 mm stroke down to 160 mm. It sets the end position but does not lock the load without continuous air pressure.
