About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX260-10
The AirTAC SAIJ80X260-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 250-260 mm usable travel window, allowing you to dial back the 260 mm nominal stroke by up to 10 mm during commissioning without adding external stops. In the 80 mm bore class, it delivers a robust 2513 N push force at 0.5 MPa, making it well-suited for heavier positioning tasks.
This unit is configured with a SUS420J2 stainless steel rod for enhanced durability against surface wear and mild moisture. The extruded aluminum barrel includes sensor grooves on both sides for direct switch mounting. While the rear adjuster and dual variable air cushions fine-tune the end-of-stroke deceleration, neither acts as a lock; live air pressure is required to hold the load in place.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX260-10 Is Used
Machine Changeover
Dial in the exact end-stop position within the 250-260 mm window when switching product sizes on a line, avoiding the need to physically swap cylinders or rework external hard stops.
Heavy Fixture Positioning
Leverage the 2513 N push force at 0.5 MPa to move heavy machining fixtures into place, using the rear screw to fine-tune the final clamping coordinates.
Assembly Line Indexing
Index large pallets through the assembly process, relying on the adjustable end-position to compensate for mechanical wear or slight variations over time.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX260-10 the Right Cylinder?
Select this 80 mm bore cylinder when your application requires substantial thrust—stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa, which may be insufficient for moving heavier jigs. The 10 mm adjustable range is ideal for final positional tuning during machine setup or product changeover, offering flexibility that a fixed-stroke SAI cannot match. For drop-in compatibility, match the exact 80 mm bore, 260 mm stroke, PT tapered port thread, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 260 mm stroke is moderately long, ensure an external guide supports the load to prevent excessive side-loading on the M20x1.5 rod thread.
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 SAIJ80 Adjustable Cylinder SAIJ80AX260-10 FAQ
A rear-mounted adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke from 260 mm down to a minimum of 250 mm. This provides a 10 mm tuning window for precise end-position setting at commissioning without altering the cylinder itself.
No. The rear adjuster and variable air cushions only set and decelerate the travel end points; they do not lock the load. If you need fail-safe load holding without live air, consider an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder.
