About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-100
The AirTAC SAIJ32X900-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates an 800-900mm usable travel window from its 900mm nominal length. Built with a SUS304 stainless steel rod and PT tapered ports, it delivers 402N of push force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Equipped with a 12mm rod and M10x1.25 thread, this unit handles moderate side loads, though a 900mm stroke benefits from an external guide to prevent rod deflection. The rear stopper allows precise end-position tuning during commissioning without swapping cylinders, while the adjustable air cushions at both ends manage deceleration across the 30-800mm/s speed range.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-100 Is Used
Variable End-Stop Tuning
Dial in the exact 800-900mm retraction point during machine setup to accommodate different product lengths without adding external physical stops.
Product Changeover
Quickly adjust the stroke window on packaging lines when switching between box sizes, using the rear screw to fine-tune the final push position.
Assembly Positioning
Achieve precise end-of-stroke positioning for pressing or placing tasks, relying on the mechanical stopper to set the exact 900mm maximum travel limit.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-100 the Right Cylinder?
Choose this 32mm bore when your application requires 402N of push force at 0.5 MPa, stepping down from a 40mm bore that yields 628N. The 100mm adjustment range is ideal for product changeovers on a line, letting you dial in the exact end-stop mechanically. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is a travel stop, not a lock. When replacing an ISO 15552 cylinder, match the 32mm bore, 900mm stroke, PT port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set.
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 SAIJ32BX900-100 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 pressure, it can deliver up to 82kgf.
The rear adjuster screw lets you shorten the effective travel from 900mm down to 800mm, creating a 100mm usable window. It acts as a mechanical stop for end-position tuning, not a lock, and requires live air to hold the load.
