About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-10S
The AirTAC SAIJ32X500-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 490-500mm usable travel window, allowing you to dial back the 500mm nominal stroke by up to 10mm during commissioning. Operating at 0.5 MPa, it delivers 402N of push force and 345N of pull force. The extruded aluminum barrel includes sensor grooves on both sides, and because this is the -S variant, it carries a magnet ready for CMSE reed or DMSE electronic solid-state switches.
This unit is built with a SUS304 stainless steel rod (code B) for corrosion resistance and uses PT tapered port threads. The 12mm rod and M10x1.25 thread provide a compact interface, but at 500mm of travel, the extended rod is susceptible to deflection under lateral stress, so an external guide is recommended for heavy offset loads. The rear adjuster acts purely as a travel stop to fine-tune the end position without adding external stops; it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-10S Is Used
Machine Changeover
Dial in the 490-500mm travel window during product size changeovers to set new end positions without physically remounting the cylinder.
End-Stop Tuning
Fine-tune the retract position by up to 10mm at commissioning to perfect the seating of a part, avoiding the need for external mechanical stops.
Material Handling
Push or divert light 402N payloads along a conveyor line, relying on the SUS304 stainless rod for environments requiring higher corrosion resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-10S the Right Cylinder?
Choose this 32mm bore if your application requires the 402N push force at 0.5 MPa; stepping down is not an option below 32mm in the SAIJ range, but stepping up to a 40mm bore yields 628N of push force if your payload increases. The adjustable stroke is selected over a fixed SAI when you need variable end-stops for rapid product changeovers, saving the effort of physically swapping cylinders to alter the travel length. For load-holding without continuous air pressure, note that the rear adjuster on this cylinder is strictly a stop, not a lock; you would need to look at the SAIL or BSAI series instead. To match this ISO 15552 replacement exactly, confirm the 32mm bore, 500mm stroke, 10mm adjustment, PT port, and -S magnet.

- ✓ 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 SAIJ32BX500-10S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum 1.0 MPa, it can deliver up to 82 kgf.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke from 500mm down to 490mm. It allows precise end-position tuning at commissioning but does not lock the load without live air pressure.
