About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-75
The AirTAC SAIJ32X290-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 402N of push force at 0.5 MPa and provides a usable travel window of 215-290mm, letting you trim the nominal 290mm stroke by up to 75mm during commissioning. This fine-tuning capability eliminates the need to swap cylinders or bolt on external stops when aligning end positions.
Built with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance, this 32mm bore unit operates at speeds of 30-800mm/s. The extruded aluminum barrel includes sensor grooves on both sides. Because this model lacks a magnet, adding position sensing later requires specifying the -S option to use AirTAC CMSE reed or DMSE electronic switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-75 Is Used
Machine Changeover
Dial in the 215-290mm travel window on the fly to accommodate different product sizes without changing the cylinder.
End-Position Tuning
Fine-tune the retract end-position during commissioning to perfectly align tooling hits without adding external stops.
Variable Stops
Ideal for diverter gates on conveyors where the actuation endpoint needs occasional adjustment to handle varying package dimensions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-75 the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires variable end-stops or frequent product changeovers, rather than committing to a fixed-stroke SAI cylinder. If your application demands greater thrust, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa, but for compact 32mm footprint requirements, this unit provides ample power. At a 290mm stroke, the 12mm rod and M10x1.25 thread handle moderate side loads, though long unsupported strokes still necessitate an external guide to prevent premature wear.
This cylinder uses a PT tapered port thread and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for positive load-holding without pneumatic pressure, consider the SAIL or BSAI series. It is dimensionally interchangeable per ISO 15552.
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 SAIJ32AX290-75 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 75mm. This creates a usable travel window of 215-290mm, allowing precise end-position tuning at commissioning without swapping the cylinder.
At 0.5 MPa operating pressure, it provides 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 82 kgf.
