About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-100S
The AirTAC SAIJ32X260-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a generous 100mm adjustment range, creating a precise 160-260mm usable travel window for highly variable end-position tuning. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet pairs directly with AirTAC CMSE reed and DMSE electronic solid-state switches for flexible positioning feedback.
This model is built with a SUS304 stainless steel rod (code B) for superior corrosion resistance and features PT tapered port threads with a G1/8 connection. The rear adjuster acts purely as a mechanical stop to fine-tune the retract distance during commissioning or product changeovers without swapping the cylinder. It utilizes adjustable air cushions at both ends to decelerate the load smoothly, but it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-100S Is Used
Product Changeover Lines
Dial in the 160-260mm travel window during format changes to accommodate different package sizes without physically swapping out actuators.
Prototype Fixturing
Fine-tune the end-stop position during machine commissioning to find the exact clamping distance before locking down the final setup.
Variable Sorting Diverters
Adjust the retract distance on the fly to push varying product profiles across a conveyor belt without repositioning the cylinder mount.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-100S the Right Cylinder?
Choose this 32mm bore when you need 402N push or 345N pull force at 0.5 MPa with extensive on-the-fly stroke trimming. The 100mm adjustment window is ideal for prototyping or lines running multiple product sizes, replacing the need to stock several fixed-stroke SAI cylinders. If your application requires less force, dropping to a smaller bore is an option, but stepping up to a 40mm bore yields 628N push force for heavier loads. For any load-holding requirements without continuous air pressure, this cylinder is insufficient; you must specify a SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock.
Because this unit features a 260mm stroke, the 12mm diameter rod with an M10x1.25 thread can experience side-loading if the load is unsupported. An external guide rail is recommended to prevent binding over this travel distance. To match this exact ISO 15552 replacement, specify: 32mm bore, 260mm nominal stroke, 100mm adjustment, PT G1/8 port, SUS304 rod, -S magnet, and a mounting set limited to Basic, FA, LB, TC, FTC, TCM1, or TCM2.

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 SAIJ32BX260-100S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At a maximum 1.0 MPa pressure, it achieves 82 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 100mm. This creates a usable travel window of 160-260mm from the 260mm nominal stroke, allowing precise end-position tuning without external stops.
