About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-100
The AirTAC SAIJ32X180-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 180 mm nominal stroke that can be dialed back by up to 100 mm, giving you an 80 to 180 mm usable travel window for precise end-position tuning during commissioning. In the 32 mm bore class, it delivers 402 N of push force at 0.5 MPa and 724 N at 0.9 MPa.
This variant uses a SUS304 stainless steel rod for corrosion resistance and runs at speeds of 30 to 800 mm/s. The rear adjuster acts purely as a mechanical stop to set the travel end and relies on the built-in air cushions for deceleration; it does not hold the load without live air pressure. For load-holding without continuous air, consider an external rod lock or related series like SAIL or BSAI.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-100 Is Used
Machine Changeovers
Dial in the exact end-position during product size changes on a packaging line without swapping cylinders or adding external stops.
Variable End Stops
Set precise retract limits for sensor probing or testing stations using the 80 to 180 mm travel window.
Assembly Calibration
Fine-tune the clamping or pressing distance during initial machine setup to accommodate material thickness variations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-100 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when you need variable end-stops for machine changeovers rather than a fixed-stroke SAI model. If your process requires higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The SAIJ32X180-100 is dimensionally interchangeable with ISO 15552 cylinders and uses a PT tapered port, a 12 mm rod with an M10x1.25 thread, and the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 180 mm stroke is below the 300 mm threshold, side-load concerns are minimal, but an external guide is still recommended for heavy lateral loads.
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 SAIJ32BX180-100 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 100 mm from the 180 mm nominal length, creating an 80 to 180 mm travel window. It functions as a mechanical stop and does not lock the load without live air pressure.
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N.
