About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-50S
The AirTAC SAIJ32X750-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 700-750 mm usable travel window, allowing you to dial back the 750 mm nominal stroke by up to 50 mm during machine commissioning. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks.
This variant includes a SUS420J2 stainless steel rod for improved corrosion resistance and a built-in magnet for CMSE reed or DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides. Because the 750 mm stroke is long relative to the 12 mm rod, an external guide is recommended to prevent excessive side-load wear.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-50S Is Used
Variable End-Stop Tuning
Dial in the exact 700 to 750 mm retract position during setup to compensate for mechanical wear or sensor drift without replacing the cylinder.
Product Changeover
Quickly adjust the stroke by up to 50 mm on a packaging line when switching to a different carton size, avoiding the need to swap out the entire actuator.
Sensor Calibration
Leverage the integrated magnet and DMSE electronic switches to confirm position feedback while fine-tuning the end stop for automated testing rigs.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-50S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa but needs precise end-position tuning without external stops. If your process demands higher thrust, stepping up to the 40 mm bore yields 628 N push force. The rear adjuster acts strictly as a travel stop for fine-tuning; it does not hold the load without live air. For fail-safe load holding, consider an SAIL or BSAI series cylinder instead.
This SAIJ32X750-50-S is dimensionally interchangeable with ISO 15552 cylinders. It features PT tapered port threads (G1/8), a 12 mm rod with an M10x1.25 thread, and operates at 30-800 mm/s. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. The 750 mm travel exceeds standard compact sizes, so ensure your framework accommodates the full extended length and supports the rod to minimize deflection.

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 SAIJ32AX750-50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw lets you shorten the effective travel from the nominal 750 mm down to 700 mm. This creates a 50 mm adjustable window for fine-tuning the retract end position at commissioning without adding external stops.
