About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-20
The AirTAC SAIJ32X260-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end-of-travel position without adding external stops. It provides a usable travel window of 240 to 260 mm, making it ideal for dialing in exact end positions during machine commissioning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This model features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It operates at speeds between 30 and 800 mm/s and utilizes adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-20 Is Used
Machine Commissioning
Dial in the exact 240 to 260 mm end position during setup without swapping cylinders or adding external shims.
Product Changeover
Quickly adjust the retract stop by up to 20 mm to accommodate different part sizes on the same production line.
Light Assembly Push
Provides 402 N of smooth push force at 0.5 MPa for positioning light components with repeatable accuracy.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-20 the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires 402 N of push force at 0.5 MPa but demands precise mechanical tuning of the retract position. If your setup requires less force, stepping down is not an option in this size range, but stepping up to a 40 mm bore provides 628 N if your payload increases. The 20 mm adjustment range is perfect for product changeovers, whereas a fixed-stroke SAI cylinder would require physical shimming or replacement to alter the end stop.
Because this unit has a 260 mm stroke, ensure the load is guided externally to prevent excessive side loading on the SUS304 rod. Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder will not hold its position without live air. For load-holding requirements, consider an AirTAC SAIL or BSAI cylinder. This SKU is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32BX260-20 FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke by up to 20 mm. This creates a usable travel window of 240 to 260 mm, which can be fine-tuned during commissioning.
At a 0.5 MPa operating pressure, the SAIJ32X260-20 provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
