About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-75
The AirTAC SAIJ32X260-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 185 to 260 mm, enabling precise end-position tuning at commissioning without the need to swap the cylinder or bolt on external stops. As a compact 32 mm bore unit, it delivers 563 N of push force at 0.7 MPa, making it well-suited for lighter-duty manipulation tasks.
This variant is built with a SUS304 stainless steel rod (material code B) for superior corrosion resistance in humid or washdown environments. It omits a piston magnet, but the extruded aluminum barrel retains sensor grooves on both sides for future flexibility. The rear adjuster acts purely as a mechanical stop to set the retract distance and is not a lock, meaning the cylinder cannot hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-75 Is Used
Product Changeovers
Quickly adapt the retract end-stop from 185 to 260 mm when switching between part sizes on a packaging line, eliminating the need for mechanical spacers.
Fixture Alignment
Fine-tune the exact clamping position during machine commissioning to ensure delicate 32 mm bore operations align perfectly without re-engineering the motion axis.
Washdown Handling
Leverage the SUS304 stainless steel rod for light-duty component pushing in environments where moisture or corrosion would quickly degrade standard carbon steel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-75 the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires 563 N of thrust at 0.7 MPa and you need to frequently dial in the end-of-stroke position. If your project demands higher force, stepping up to the 40 mm bore yields 879 N at the same pressure. The generous 75 mm adjustment range on this 260 mm stroke model is ideal for product changeovers on a line, allowing operators to fine-tune the retract distance on the fly rather than machining custom spacers. For fixed-travel needs without the adjuster, the standard SAI series is the direct alternative.
Because this unit features a 260 mm stroke, the 12 mm diameter rod and M10x1.25 thread provide a robust interface, but long unsupported strokes still require an external guide to prevent excessive side-loading. It uses a PT G1/8 tapered port and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your process requires true load-holding without continuous air pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead.

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 SAIJ32BX260-75 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 75 mm. This creates a usable travel window between 185 and 260 mm, allowing you to set the exact retract position without replacing the cylinder. The adjuster is a travel stop, not a lock, so it cannot hold a load without live air pressure.
At a 0.7 MPa operating pressure, this double-acting cylinder provides 563 N of push force and 345 N of pull force. It operates at a speed range of 30-800 mm/s, supported by adjustable air cushions at both ends that deliver 27 mm of cushioning length to decelerate the load smoothly.
