About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-75
The AirTAC SAIJ80X1000-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 2513N push force at 0.5 MPa. It features a carbon steel piston rod and PT tapered port threads. The integrated rear stopper allows you to fine-tune the effective travel anywhere within a 925 to 1000mm window, providing exact end-position calibration without swapping out components.
Because the nominal 1000mm stroke is exceptionally long, the 25mm rod diameter and M20x1.5 rod thread provide crucial structural rigidity, though an external guide is highly recommended to manage side loads. This extruded aluminum profile cylinder includes sensor grooves on both sides and supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-75 Is Used
Variable End Positioning
Dial in the exact retraction point within the 925-1000mm range during commissioning to accommodate different product lengths without changing the cylinder.
Long-Stroke Material Handling
Pushes or positions heavy loads along a conveyor using 2513N of force, relying on the 25mm rod to maintain stability over the extended 1-meter travel.
Machine Changeover Setup
Quickly adjust the stroke stopper on automated assembly lines when switching between product variants, avoiding the downtime of mechanical modifications.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-75 the Right Cylinder?
Choose this 80mm bore when you need significantly more thrust than a 63mm cylinder (which provides 1559N push at 0.5 MPa), but want to avoid the larger footprint of a 100mm bore. The adjustable stroke is ideal for machine setups requiring variable end stops or product changeovers, letting you dial in the 925-1000mm travel range on the fly instead of installing fixed stops.
When replacing an ISO 15552 cylinder, match the 80mm bore, 1000mm stroke, 75mm adjustment, PT port threads, and your required mounting hardware. For any stroke of 1000mm, always support the load with an external guide to prevent rod bending. If your application requires true load-holding without continuous air pressure, the rear adjuster will not suffice; consider an external rod lock or the AirTAC SAIL lock variant instead.
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 SAIJ80X1000-75 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides a push force of 2513N and a pull force of 2268N. At the maximum pressure of 0.9 MPa, the push force increases to 4523N.
The rear adjusting screw acts as a mechanical stopper that trims the effective travel. For this 1000mm stroke model, the -75 code means you can shorten the stroke by up to 75mm, creating a usable travel window of 925 to 1000mm. It only sets the end position and does not lock the load.
