Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-30
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 260mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-30
The AirTAC SAIJ32X260-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down by 30 mm, creating a usable 230-260 mm stroke window. This bore delivers 402 N of push thrust at 0.5 MPa, making it well-suited for lighter-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
Equipped with a SUS304 stainless steel rod and PT tapered port threads, this unit handles standard pneumatic demands reliably. The rear adjuster acts purely as a mechanical stop to set the retraction end position during commissioning; it does not lock or hold the load without live air pressure. For applications requiring position holding without continuous air, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-30 Is Used
Machine Changeover
Dial in the exact retraction end-position during product size changeovers without swapping the cylinder or bolting on external stops.
Variable End Stops
Set a precise 230-260 mm travel window on the assembly line to accommodate slight variations in incoming part dimensions.
Commissioning Fine-Tune
Trim the stroke by up to 30 mm during initial setup to perfectly time the pick-and-place motion without reprogramming the PLC.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-30 the Right Cylinder?
Choose this 32 mm bore when your application requires precise end-stop tuning without adding external stops; if you need less force, stepping down is not an option in the SAIJ range, but stepping up to a 40 mm bore yields 628 N of push thrust at 0.5 MPa. The 260 mm stroke on this model approaches the mid-range for a 32 mm bore, and while the 12 mm rod with M10x1.25 thread provides decent support, any stroke of 300 mm or more requires an external guide to prevent excessive side-loading.
This adjustable-stroke model is selected over a fixed SAI cylinder when machine setups require variable product sizes or changeovers. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. It is dimensionally interchangeable per ISO 15552, features a PT port, and operates without a magnet (no -S).

- ✓ 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 SAIJ32BX260-30 FAQ
At a 0.5 MPa operating pressure, the 32 mm bore provides 402 N of push thrust and 345 N of pull thrust. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear mechanical adjuster acts as a stopper that lets you shorten the nominal 260 mm stroke by up to 30 mm, creating a 230-260 mm usable travel window. It sets the end position but does not lock the load without live air.
