About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-100S
The AirTAC SAIJ32X900-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing an 800 to 900 mm usable travel window for exact end-position tuning. Built with a SUS304 stainless steel rod and a PT tapered port, it delivers 402N of push force at 0.5 MPa. The extruded aluminum barrel features sensor grooves on both sides, and the integrated magnet supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection.
Because the 900 mm stroke is substantial for a 32 mm bore, the 12 mm rod and M10x1.25 thread need careful alignment to manage side loads. The rear adjuster acts purely as a travel stop to decelerate the piston alongside the variable air cushions, meaning it cannot hold a load without continuous live air pressure. For load-holding requirements without air, an external pilot-operated check valve or a related SAIL lock cylinder is required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-100S Is Used
Variable Length Stops
Dial in the exact retraction point within the 800-900 mm window during machine setup, allowing rapid accommodation of different product lengths without changing hardware.
Product Changeover
Quickly adjust the end-stop position on a packaging line to handle varying box sizes, using the rear screw to fine-tune the travel distance on the fly.
Sensor Positioning
Leverage the integrated magnet with DMSE electronic sensors to confirm the adjusted end-position, ensuring reliable feedback across the adjusted travel range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-100S the Right Cylinder?
Choose this adjustable-stroke model when your assembly requires variable end-stops or product-size changeovers without physically swapping the cylinder, unlike a fixed-stroke SAI. If your application needs less force, stepping down is not an option below 32 mm, but stepping up to a 40 mm bore yields 628N of push force at 0.5 MPa. Given the 900 mm stroke, always use an external guide rail to support the load and prevent excessive side-loading on the rod.
This SAIJ32X900-100-S is dimensionally interchangeable per ISO 15552 mounting interfaces. To match this exact replacement, specify the 32 mm bore, 900 mm stroke, 100 mm adjustment range, PT port thread, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting options, SUS304 rod, and the -S 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 SAIJ32BX900-100S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm, creating an 800 to 900 mm usable travel window. It functions as a mechanical stop to set the end position and does not lock the load without live air pressure.
