About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-40S
The AirTAC SAIJ32X500-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 460-500mm usable travel window, allowing you to dial back the 500mm nominal stroke by up to 40mm during commissioning. Delivering 402N of push force at 0.5 MPa, it features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads.
This model includes a magnet (-S) for position sensing with AirTAC CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position without swapping cylinders. It uses variable air cushions at both ends and shares the standard extruded aluminum barrel with sensor grooves on both sides.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-40S Is Used
Machine Changeover
Quickly fine-tune the retract end position by up to 40mm when switching between product sizes on a packaging line, eliminating the need for external stopper blocks.
Variable End-Stops
Dial in the exact 460-500mm travel window required for delicate placement tasks without physically modifying the cylinder mounting or changing the whole actuator.
Commissioning Setup
Perfect for long-stroke assemblies where minor mechanical variances need to be absorbed at startup, letting operators set the exact retract distance via the rear screw.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-40S the Right Cylinder?
Choose this 32mm bore when an application requires precise end-position tuning on a long stroke, delivering 345N pull force at 0.5 MPa. The 40mm adjustment range is perfect for machine setups requiring variable end-stops during product changeovers, avoiding the need for fixed-stroke SAI cylinders or external stops. If your setup needs higher thrust, stepping up to a 40mm bore yields 528N of pull force at 0.5 MPa.
Because the stroke is 500mm, the 12mm diameter rod and M10x1.25 thread face higher deflection risks; an external guide is recommended to prevent side-load damage. To replace this ISO 15552 cylinder, match the 32mm bore, 500mm stroke, 40mm adjustment, PT port, Basic/LB/TC mounting, and -S magnet. Note that the rear adjuster and air cushions do not hold the load without live air; for true load-holding, consider an SAIL or BSAI cylinder.
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 SAIJ32AX500-40S FAQ
At an operating pressure of 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach up to 724N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 500mm nominal stroke by up to 40mm. This creates a 460-500mm usable travel window for fine-tuning the end position without replacing the cylinder.
