About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-30
The AirTAC SAIJ32X290-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 260-290 mm usable travel window, allowing you to dial back the nominal 290 mm stroke by up to 30 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-30 Is Used
Product Changeovers
Quickly adjust the 260-290 mm travel window to accommodate different product lengths on a packaging line without changing out the physical cylinder.
End-Stop Tuning
Fine-tune the exact retract position during machine commissioning to align tools perfectly, using the rear screw rather than shimming.
Light Diverter Arms
Drive lighter conveyor routing flaps where the 402 N push force is adequate and the SUS304 rod prevents corrosion in humid environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-30 the Right Cylinder?
Choose this 32 mm bore when 402 N of push force at 0.5 MPa is sufficient, stepping up to the 50 mm bore if your application requires 982 N. An adjustable stroke is ideal for product-size changeovers on a line, letting you fine-tune the retract end position without swapping the cylinder or adding external stops. For fixed travel, a standard SAI cylinder is simpler.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 290 mm stroke, PT ports, and mounting choice. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Because the 290 mm stroke is relatively long for this bore size, ensure external guides support any side loads to protect the 12 mm rod. For load-holding without air, use a SAIL or BSAI cylinder instead.
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 SAIJ32BX290-30 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster screw lets you shorten the effective stroke by up to 30 mm, creating a 260-290 mm travel window. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
