About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-30
The AirTAC SAIJ32X350-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 320-350 mm usable travel window by allowing you to dial back the 350 mm nominal stroke by up to 30 mm. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread.
The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Because the stroke exceeds 300 mm on a 12 mm rod, an external guide is recommended to prevent excessive side-loading. The rear adjuster acts purely as a mechanical stop for end-position tuning, not a lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-30 Is Used
Machine Changeover
Dial in the 320-350 mm end position during product size changes without bolting on external stops or replacing the cylinder.
End-Position Tuning
Fine-tune the retract stroke at commissioning using the rear adjuster to perfectly time the 12 mm rod extension.
Corrosive Environments
Leverage the SUS304 stainless steel rod for light-duty pushing in packaging or food processing lines requiring washdown.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX350-30 the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force (345 N pull) at 0.5 MPa with precise end-position control during commissioning. If your application requires less force, dropping down is not an option in this frame, but stepping up to a 40 mm bore yields 628 N push force. The adjustable stroke is ideal for product changeovers on a line, saving you from swapping cylinders or adding external stops compared to a fixed SAI model.
For ISO 15552 replacement matching, verify the 32 mm bore, 350 mm stroke, PT port thread, and the absence of a magnet. Remember that a plain SAIJ does not hold loads without live air pressure; the rear stopper only sets the travel end. For true load-holding, consider the SAIL or BSAI series. The mounting set includes 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 SAIJ32BX350-30 FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 30 mm. This creates a 320-350 mm usable travel window, allowing you to fine-tune the end position without swapping cylinders.
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 up to 724 N push force at 0.9 MPa.
