About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-10S
The AirTAC SAIJ32X290-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 10 mm of end-position trimming. This yields a usable travel window of 280 to 290 mm, enabling precise commissioning calibration without external stops. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS420J2 stainless steel rod and a built-in magnet for position sensing.
Unlike fixed-stroke SAI units, this adjustable variant allows rapid machine changeovers by dialing in the retract end-stop. The extruded aluminum barrel includes sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic switches. It uses a PT tapered port thread and relies on variable air cushions at both ends to decelerate the load smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-10S Is Used
End-Stop Calibration
Dial in the exact 280 to 290 mm travel distance during machine commissioning without swapping cylinders or adding external mechanical stops.
Product Changeover
Quickly adjust the retract position by up to 10 mm to accommodate varying package lengths on a packaging line.
Sensor-Ready Positioning
Leverage the integrated magnet and dual sensor grooves to mount CMSE or DMSE switches for precise end-of-stroke verification.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-10S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa (or 724 N at 0.9 MPa) alongside variable end-stops. If your setup demands less force, stepping down is not an option in this series, but stepping up to a 40 mm bore yields 628 N at 0.5 MPa. The 10 mm adjustment window is ideal for fine-tuning product-size changes on a line.
Because the nominal stroke is 290 mm, you must use an external guide to prevent side-load damage to the 12 mm rod and M10x1.25 thread. Remember that the rear adjuster and air cushions act only as travel stops and deceleration; they do not hold the load without live air. For load-holding without pressure, select a SAIL or BSAI cylinder. To match this ISO 15552 replacement, verify the 290 mm stroke, 10 mm adjustment, PT G1/8 port, and the -S magnet.
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 SAIJ32AX290-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw allows you to shorten the 290 mm nominal stroke by up to 10 mm, creating a 280 to 290 mm usable travel window. It acts as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
