About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-30
The AirTAC SAIJ32X900-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 900 mm stroke that can be dialed back by up to 30 mm, giving you a precise 870-900 mm usable travel window for exact end-position tuning at commissioning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This long-stroke unit is built with a SUS304 stainless steel rod for superior corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Because the stroke reaches 900 mm, the 12 mm rod should be guided externally to prevent side-load wear on the seals.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-30 Is Used
Machine Setup Tuning
Dial in the exact 870-900 mm end position during commissioning to perfectly align long-trroke actuators without adding external stopper blocks.
Product Size Changeover
Quickly adjust the retract distance on automated lines when handling different product lengths, saving time on manual changeovers.
Long-Stroke Conveying
Manage the precise release point of parts on a 900 mm stroke conveyor transfer station, ensuring smooth handoffs without cylinder replacement.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-30 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your machine setup requires variable end stops or product-size changeovers without physically swapping the cylinder or adding external stops. If you need higher thrust, stepping up to the 40 mm bore provides 628 N of push force at 0.5 MPa.
The rear adjuster on this SAIJ model acts as a travel stop to fine-tune the retract position; it does not hold the load without live air pressure. For true load-holding without continuous air, select the SAIL (air-released lock) or BSAI (clamp-lock) series. This profile cylinder is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32BX900-30 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 801 N of push force.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm. This creates a usable travel window of 870 to 900 mm, letting you fine-tune the end position at commissioning without altering the air cushion or swapping the cylinder.
