About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-100S
The AirTAC SAIJ80X700-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 600 to 700 mm. It delivers a robust 2513 N pull force at 0.5 MPa and a 4523 N push force at 0.9 MPa, making it well-suited for heavy-duty positioning tasks. The extruded aluminum barrel features sensor grooves on both sides, and this -S variant includes a magnet for direct compatibility with CMSE reed and DMSE electronic solid-state switches.
This model utilizes a SUS420J2 stainless steel piston rod (code A) with an M20x1.5 thread, offering solid resistance to lateral stress, though the lengthy 700 mm stroke still necessitates an external guide to prevent binding. The rear adjuster functions strictly as a mechanical stop to fine-tune the retract position during commissioning or product changeover without swapping the cylinder. It does not hold the load without live air pressure; for true load-holding without continuous air, an external rod lock or the BSAI clamp-lock series is required.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-100S Is Used
Product Changeover Dials
Quickly adjust the retract distance by up to 100 mm when switching a production line to a different package or part size, avoiding physical spacer swaps.
Machine Setup Tuning
Fine-tune the end-of-stroke position during commissioning to perfectly time heavy-duty pressing or lifting motions without replacing the whole actuator.
Variable End Stops
Set precise retraction limits on conveyor sorting gates or diverter arms, allowing operators to modify the travel window between 600 and 700 mm on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-100S the Right Cylinder?
Select this 80 mm bore unit when your application demands high force combined with variable end-stop positioning. If you need less thrust, stepping down to a 63 mm bore yields 1402 N of pull force at 0.5 MPa, whereas moving up to a 100 mm bore provides 3681 N of pull force. The SAIJ80X700-100-S is chosen over a fixed-stroke SAI specifically to dial in the retract end-position during machine setup, saving the effort of adding external stops or machining custom spacers. Because the nominal stroke is 700 mm, an external guide is strongly recommended to manage side loads and prevent rod deflection. This configuration includes PT tapered port threads, a -S magnet for sensing, and supports SAIJ mounting options 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 SAIJ80 Adjustable Cylinder SAIJ80AX700-100S FAQ
At a 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster acts as a mechanical stop that allows you to trim the effective stroke back by up to 100 mm from the nominal 700 mm, providing a usable travel window of 600 to 700 mm. It requires live air to move and does not lock or hold the load without continuous pressure.
