About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-100S
The AirTAC SAIJ32X500-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 402N of push force and 345N of pull force at 0.5 MPa, utilizing a 12mm SUS304 stainless steel rod. The built-in rear stopper allows you to fine-tune the effective travel window from 400 to 500 mm without adding external stops.
Equipped with a magnet for position sensing, this unit supports AirTAC CMSE reed and DMSE solid-state switches via the dual-side sensor grooves. It features PT tapered G1/8 ports, 27mm cushions at both ends, and operates at speeds of 30-800 mm/s. The stainless rod provides excellent corrosion resistance, and the mounting footprint is dimensionally interchangeable per ISO 15552 standards.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-100S Is Used
Machine Changeover
Dial in the exact end-position during product size changeovers on a packaging line, utilizing the 400-500mm travel window to adapt quickly without swapping cylinders.
Variable End Stops
Adjust the retract stroke on the fly for conveyor sorting arms or diverters, allowing precise control over the travel distance for varying package dimensions.
Assembly Calibration
Fine-tune the pressing or clamping depth during machine commissioning to ensure delicate components are assembled accurately within the 100mm adjustment range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-100S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires commissioning fine-tuning or frequent product-size changeovers, as the rear screw allows precise end-position tuning without swapping the cylinder. If your application needs higher force, stepping up to a 40mm bore provides 628N of push force at 0.5 MPa, but the 32mm bore is ideal for lighter loads. Because the nominal stroke is 500mm, an external guide is recommended to prevent excessive side-loading on the rod.
For load-holding applications without live air pressure, note that the rear adjuster acts only as a travel stop and the air cushions manage deceleration; neither functions as a lock or brake. For secure load holding, consider the SAIL or BSAI series, or use an external pilot-operated check valve. This SKU specifies a PT port thread, SUS304 rod material, and includes a magnet for CMSE/DMSE sensors.

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 SAIJ32BX500-100S FAQ
At an operating pressure of 0.5 MPa, this 32mm bore cylinder provides a push force of 402N and a pull force of 345N. At 0.7 MPa, the push force increases to 563N.
The rear adjuster screw allows you to shorten the effective stroke by up to 100mm. For this 500mm nominal stroke cylinder, this creates a usable travel window of 400 to 500mm, enabling precise end-position tuning without external stops.
