About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-10
The AirTAC SAIJ32X900-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel by up to 10 mm. This creates a usable stroke window of 890-900 mm, allowing you to fine-tune the end position at commissioning without swapping the cylinder or adding external stops. It delivers 402 N of push thrust at 0.5 MPa and operates at speeds of 30-800 mm/s.
This model uses a SUS304 stainless steel rod for superior corrosion resistance and features a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-10 Is Used
Machine Setup Tuning
Dial in the exact 890-900 mm end position during equipment commissioning without machining custom spacers.
Product Changeover
Quickly adjust the stroke by up to 10 mm to accommodate slightly different product sizes on the same line.
Long-Travel Ejection
Utilize the 900 mm reach for ejecting parts while fine-tuning the retraction stop to time the release perfectly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-10 the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa with precise end-position tuning over a long 900 mm travel. If your application requires less force, stepping down is not an option in this series, but stepping up to a 40 mm bore yields 628 N push force. The adjustable stroke is ideal for machine setups requiring variable end-stops versus a fixed-stroke SAI cylinder.
Because this cylinder has a 900 mm stroke, the M10x1.25 rod will experience side-loading leverage; an external guide is highly recommended to prevent premature wear. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on the rear stopper. This unit is dimensionally interchangeable with ISO 15552 cylinders and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

- ✓ 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 SAIJ32BX900-10 FAQ
It provides 402 N of push thrust and 345 N of pull thrust at 0.5 MPa, with an operating speed range of 30-800 mm/s.
The rear adjuster screw allows you to shorten the 900 mm nominal stroke by up to 10 mm, creating a usable travel window of 890-900 mm. It functions as an end-position stop, not a load lock.
