About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-10
The AirTAC SAIJ32X50-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 40 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 superior corrosion resistance and uses PT tapered G1/8 ports.
The rear adjustment screw acts purely as a travel stop to set the retract end position, meaning it cannot hold a load without live air pressure. It shares the standard extruded aluminum barrel with dual sensor grooves, but utilizes a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) omitting FB and CA options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-10 Is Used
Machine Setup Tuning
Dial in the exact 40 to 50 mm retract position during initial commissioning to perfect pick-and-place trajectories without machining custom spacers.
Product Size Changeover
Quickly adapt the cylinder's effective stroke on packaging lines when running different product lengths, minimizing downtime between batches.
Variable End Stops
Use the rear stopper screw to set precise retract limits for delicate pressing tasks, preventing overtravel while maintaining a 30-800 mm/s speed range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-10 the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N of push force at 0.5 MPa and requires exact end-position tuning during commissioning. If your process demands less force, stepping down is not an option in this series, but if you need higher force, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. The adjustable stroke is ideal for product changeovers where a fixed-stroke SAI cylinder would require physical shimming. Because the plain SAIJ lacks a lock, use a SAIL or BSAI cylinder if you need fail-safe load holding without live air. For a true ISO 15552 replacement match, specify bore 32, stroke 50, 10 mm adjustment, PT ports, your desired mounting, and no magnet.

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 SAIJ32AX50-10 FAQ
The rear adjuster screw lets you shorten the nominal 50 mm stroke by up to 10 mm, providing a usable travel window of 40 to 50 mm. The adjuster functions only as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
At an operating pressure of 0.5 MPa, this 32 mm bore double-acting cylinder generates 402 N of push force and 345 N of pull force. It can reach a maximum of 82 kgf at 1.0 MPa.
