About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-30S
The AirTAC SAIJ32X260-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 260 mm travel by up to 30 mm. This creates a usable 230-260 mm stroke window, allowing precise end-position tuning at commissioning without swapping out the cylinder or adding external stops. It delivers 402 N of push thrust at 0.5 MPa, making it well-suited for lighter-duty manipulation tasks.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a built-in magnet for position sensing with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel incorporates sensor grooves on both sides, and fluid supply is via PT tapered G1/8 ports. The rear adjuster acts purely as a mechanical stop to set the travel end; it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-30S Is Used
Machine Setup & Changeover
Fine-tune the 230-260 mm travel window during product size changeovers on a packaging line without physically replacing the cylinder.
Variable End-Stop Positioning
Use the rear adjustment screw to set precise retract end-positions for different tooling heights or sensor targets on the fly.
Light-Duty Clamping
Leverage the 402 N push force at 0.5 MPa for securing light workpieces, utilizing the 12 mm rod for stable, repeatable actuation.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-30S the Right Cylinder?
Choose this 32 mm bore when your application requires the 402 N push force at 0.5 MPa. If your setup needs substantially more clamping power, stepping up to the 40 mm bore yields 628 N of push force, while lighter duties might use a smaller unit. The adjustable stroke is highly beneficial for machine setups requiring variable end-stops or product-size changeovers, providing flexibility that a fixed-stroke SAI cylinder cannot match.
Because the total stroke is 260 mm, the 12 mm diameter rod and M10x1.25 thread should be guided externally if significant side loads are present to prevent uneven wear. Remember that the rear adjuster is a travel stop, not a locking device; the SAIJ will not hold its position without live air. For true fail-safe load holding, consider the SAIL or BSAI series instead. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.

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 SAIJ32BX260-30S FAQ
The rear adjuster screw allows you to shorten the effective travel by up to 30 mm from the 260 mm nominal stroke, providing a usable 230-260 mm window. It functions as a mechanical stop to decelerate the piston and does not lock the load without continuous air pressure.
It provides 402 N of push thrust and 345 N of pull thrust at 0.5 MPa. The built-in magnet (-S) is fully compatible with AirTAC CMSE reed and DMSE solid-state sensors mounted in the dual-side barrel grooves.
