About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-40S
The AirTAC SAIJ80X1000-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N of push force at 0.5 MPa and features a 1000mm nominal stroke that can be fine-tuned down by up to 40mm, yielding a precise 960-1000mm usable travel window. A carbon steel rod and PT tapered port threads come standard, while the integrated -S magnet enables position sensing with CMSE reed or DMSE electronic switches.
Because the adjuster acts as a mechanical stop on the retract end, you can dial in the exact end position during commissioning without adding external stops. This extruded aluminum profile cylinder includes variable air cushions at both ends to decelerate the load smoothly. Remember that the rear stopper and cushion only manage the travel end; they do not function as a lock to hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-40S Is Used
Long-Stroke Conveying
Manages material push-off on long conveyor lines, using the 960-1000mm travel window to perfectly align stops for varying pallet depths without physical disassembly.
Machine Changeover
Ideal for packaging equipment that processes multiple carton sizes, allowing operators to dial in the exact 40mm retraction stop during format changeovers.
Extended Assembly Pressing
Provides steady 2513N clamping force for large component alignment, relying on the rear adjuster to set precise bottoming positions for delicate parts.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-40S the Right Cylinder?
Selecting this 80mm bore cylinder makes sense when your application requires the 2513N push force at 0.5 MPa (or 4523N at 0.9 MPa) alongside a highly variable end position. If your setup only needs 1559N of push force, stepping down to a 63mm bore saves space, but the 80mm rod provides superior side-load resilience. For a 1000mm stroke, that larger 25mm rod diameter is critical, though you must still use an external guide to prevent sagging and binding over the extended length.
The adjustable stroke is chosen over a fixed SAI cylinder when you need on-the-fly product changeovers or commissioning fine-tuning. This -S variant supports AirTAC CMSE and DMSE sensors for accurate positioning feedback. It uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552. If your machine requires true load-holding without continuous air pressure, you will need an external rod lock or a different AirTAC series like the SAIL or BSAI.

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 SAIJ80X1000-40S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. If you increase the pressure to 0.9 MPa, the push force rises to 4523N.
The rear mechanical stopper allows you to shorten the effective stroke by up to 40mm. This creates a 960-1000mm adjustable travel window, enabling fine-tuning of the end position at commissioning without swapping the cylinder.
