About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-75S
The AirTAC SAIJ32X650-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 402N of push force at 0.5 MPa and provides a usable travel window of 575-650mm, letting you dial back the nominal 650mm stroke by up to 75mm during commissioning. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
This unit uses a SUS420J2 stainless steel rod for improved corrosion resistance and accepts PT tapered port threads. It operates at 30-800mm/s and carries adjustable air cushions at both ends to manage end-of-stroke deceleration. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without adding external stops.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract position between 575mm and 650mm during machine setup without physically replacing the actuator.
Product Size Changeover
Quickly adapt a packaging line to different package lengths by adjusting the rear stopper screw on the fly.
Long-Stroke Forming
Leverage the 402N push force and 650mm travel for extended reach pressing tasks, using the adjuster to limit over-travel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-75S the Right Cylinder?
Choose this 32mm bore when your application requires 402N of push force at 0.5 MPa and a variable end-stop. The adjustable stroke is ideal for product changeovers, allowing you to shorten the travel from 650mm down to 575mm without swapping the cylinder. If you need more thrust, stepping up to a 40mm bore yields 628N. To replace an ISO 15552 cylinder, match the 32mm bore, 650mm stroke, PT G1/8 port, Basic/LB/TC mounting, and -S magnet.
Because the 650mm stroke is long relative to the 12mm rod diameter, an external guide is recommended to prevent excessive side-loading and premature seal wear. Remember that the rear adjuster and air cushions only set the travel end; they do not hold the load without live air. For dead-stop holding, use an external pilot-operated check valve or explore SAIL lock cylinders.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ32AX650-75S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 650mm down to 575mm. It is a travel stop, not a lock, so it will not hold the load without live air pressure.
At 0.5 MPa, it provides 402N of push force and 345N of pull force. The -S suffix means it has a magnet compatible with AirTAC CMSE reed and DMSE solid-state sensors.
