About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX280-10S
The AirTAC SAIJ32X280-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 270-280 mm window. Delivering 402 N of push force at 0.5 MPa, it suits light-load positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This variant uses a SUS420J2 stainless steel rod for improved corrosion resistance and accepts PT tapered port threads. The rear adjustment mechanism acts purely as a mechanical stop to set the end position, meaning it will not hold the load dynamically without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX280-10S Is Used
End-Position Tuning
Dial in the exact retract distance within a 270-280 mm window during machine commissioning without physically swapping out the cylinder.
Product Changeover
Quickly adjust the 10 mm stroke stopper on the line to accommodate slight variations in incoming product sizes or packaging formats.
Light-Load Positioning
Utilize the 402 N push force and CMSE/DMSE sensor compatibility to accurately index light materials along an assembly conveyor.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX280-10S the Right Cylinder?
Choose this 32 mm bore cylinder when you need 402 N of thrust at 0.5 MPa and a 280 mm nominal stroke that can be dialed back by up to 10 mm during commissioning. This built-in adjustability eliminates the need to swap cylinders or add external stops for minor end-position tweaks. If your application requires less force, stepping down to a 20 mm bore yields 188 N, while moving up to a 40 mm bore provides 628 N. To match this ISO 15552 footprint, specify the 32 mm bore, 280 mm stroke, 10 mm adjustment, PT ports, and the -S magnet option for CMSE or DMSE sensors.
Because the nominal stroke is 280 mm, the M10x1.25 rod and M10 thread size should be evaluated for side-load tolerance. Long unsupported strokes require an external guide to prevent rod bending and premature seal wear. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR mounts.

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 SAIJ32AX280-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If operated at 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 280 mm nominal stroke down to 270 mm. It sets the end position but does not lock the load without continuous air pressure.
