About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-30S
The AirTAC SAIJ32X900-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with 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 and a PT G1/8 port. The integrated -S magnet enables seamless position detection with AirTAC CMSE reed or DMSE electronic solid-state sensors.
With a 900mm nominal stroke and a 30mm adjustment range, this model provides an exact 870-900mm usable travel window. This built-in rear stopper allows you to fine-tune the retract end position during commissioning without adding external stops or swapping the cylinder. The extruded aluminum barrel features sensor grooves on both sides, and the mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-30S Is Used
Commissioning Fine-Tuning
Dial in the exact retract position within the 870-900mm window during machine setup, eliminating the need to machine custom external spacers.
Product Size Changeover
Quickly adjust the end-stop by up to 30mm on packaging lines to accommodate varying carton lengths without changing out the actuator.
Long-Stroke Positioning
Verify exact end-of-travel limits on extended 900mm strokes using the integrated -S magnet alongside CMSE or DMSE sensors.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX900-30S the Right Cylinder?
Choose this 32mm bore when an application requires precise end-position tuning within a 870-900mm travel window, avoiding the need to physically swap cylinders during product changeovers. If your setup needs greater thrust, stepping up to the 40mm bore increases push force to 628N at 0.5 MPa. Because the 900mm stroke is long relative to the 12mm rod diameter, an external guide is recommended to prevent excessive side-loading and premature seal wear.
As an adjustable-stroke alternative to the fixed SAI cylinder, the rear screw acts solely as a travel stop and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series. To match this ISO 15552 interchangeable cylinder exactly, specify the 32mm bore, 900mm stroke, 30mm adjustment, PT tapered port, SUS304 rod, and -S magnet.

- ✓ 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 SAIJ32BX900-30S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
The rear adjuster screw allows you to shorten the effective travel from the 900mm nominal stroke by up to 30mm, creating a usable 870-900mm window. It functions as a mechanical stop and does not lock the load without air pressure.
