About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-50
The AirTAC SAIJ32X290-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 290 mm travel back by up to 50 mm, creating a precise 240-290 mm usable window. It delivers a 0.5 MPa push force of 402 N, making it well-suited for lighter-duty positioning tasks.
This variant uses a SUS420J2 stainless steel piston rod for enhanced corrosion resistance and features a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is supplied without a magnet for position detection.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-50 Is Used
Machine Setup
Dial in the exact retract distance during equipment commissioning to align tools perfectly without machining spacers.
Product Changeover
Quickly adapt the end-stop from 240 to 290 mm on automated lines handling different part lengths.
Variable End Stops
Fine-tune the travel window on light-force assembly stations requiring precise 402 N positioning.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-50 the Right Cylinder?
Choose this 32 mm bore when your application requires exact end-position tuning at commissioning or during product changeovers without swapping the cylinder or adding external stops. If your setup demands higher thrust, stepping up to the 40 mm bore yields a 628 N push force at 0.5 MPa.
Because the stroke is 290 mm, the 12 mm rod and M10x1.25 thread should be paired with an external guide to manage side loads over the extended travel. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series. This model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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.
