About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-50S
The AirTAC SAIJ32X260-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 210 to 260 mm, letting you dial back the 260 mm nominal stroke by up to 50 mm without adding external stops. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors.
The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It operates at speeds between 30 and 800 mm/s and uses PT tapered port threads (G1/8). The rear adjustment screw acts purely as a mechanical stop to set the retract end position; it does not lock or hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-50S Is Used
Machine Changeover
Fine-tune the 210-260 mm retract end-stop during product size changes on a packaging line without physically swapping the cylinder.
Variable End Stops
Dial in the exact retraction position for multi-format tooling setups, using the 50 mm rear adjustment screw to compensate for mechanical tolerances.
Sensor-Ready Positioning
Track the piston position using the integrated magnet with DMSE electronic sensors, ensuring the adjusted travel endpoint is accurately detected.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-50S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa and you need precise end-position tuning during commissioning or product changeover. If your force requirements are lower, stepping down is not an option in this ISO series, but stepping up to a 40 mm bore provides 628 N of push force. The adjustable stroke is ideal for variable end stops, whereas a fixed-stroke SAI cylinder lacks this fine-tuning capability.
Because this model features a 260 mm stroke, the 12 mm rod diameter and M10x1.25 rod thread should be paired with an external guide if the load is heavy or subject to high side loads. As a dimensionally interchangeable ISO 15552 cylinder, it replaces units using the same bore, 260 mm stroke, 50 mm adjustment, PT G1/8 ports, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interfaces. It omits FB, CA, CB, and CR mounts.

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 SAIJ32AX260-50S FAQ
The rear adjuster screw allows you to shorten the 260 mm nominal stroke by up to 50 mm, creating a usable travel window of 210-260 mm. It acts as a mechanical stop to fine-tune the end position but does not lock or hold the load without continuous air pressure.
At an operating pressure of 0.5 MPa, the SAIJ32X260-50-S provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
