About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-30S
The AirTAC SAIJ32X290-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 260 to 290 mm window during commissioning. Delivering 402 N of push force at 0.5 MPa, it provides precise end-position tuning for product changeovers without requiring external stops or cylinder replacement.
This configuration features a SUS420J2 stainless steel rod for enhanced corrosion resistance and a built-in magnet compatible with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered port thread ensures a reliable, sealed pneumatic connection tailored to the 32 mm bore.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-30S Is Used
Variable End-Stop Setup
Dial in the exact retract position within the 260-290 mm window for precise machine setup without swapping cylinders or adding external stopper blocks.
Product Size Changeover
Quickly adapt automated lines to different product lengths by adjusting the rear screw up to 30 mm during format changeovers.
Light-Force Positioning
Leverage the 402 N push force at 0.5 MPa for delicate handling and positioning tasks requiring exact end-of-stroke tuning.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-30S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires variable end-stops or frequent setup adjustments, stepping down from a 40 mm bore (which provides 628 N push at 0.5 MPa) if lower force and a compact footprint are needed. Because the 290 mm stroke is substantial, ensure you use an external guide to support the load and mitigate side-load stress on the 12 mm rod.
As an ISO 15552 dimensionally interchangeable cylinder, it replaces standard profile cylinders using the exact bore, 290 mm stroke, 30 mm adjustment, PT G1/8 port, and -S magnet. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. For secure load-holding, consider the SAIL or BSAI series instead. The SAIJ 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 SAIJ32AX290-30S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 30 mm, providing a usable travel window of 260 to 290 mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
At an operating pressure of 0.5 MPa, the SAIJ32X290-30-S provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N of push force at 0.9 MPa.
