About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX950-100
The AirTAC SAIJ80X950-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 2513N of push force at 0.5MPa and utilizes a PT G3/8 port. With a 950mm nominal stroke and a 100mm adjustment range, you can dial back the effective travel to anywhere within an 850-950mm window. This enables precise end-position tuning at commissioning without swapping out the entire unit or adding external stops.
This specific SKU is built with an SUS420J2 stainless steel rod (code A) for superior corrosion resistance. Because the 950mm stroke is long, the 25mm rod diameter and M20x1.5 rod thread provide robust support, though an external guide is still recommended to manage side loads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily mount position switches if needed.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX950-100 Is Used
Variable End-Stop Tuning
Fine-tune the retract position within the 850-950mm window during machine commissioning to achieve precise stopping without external shims.
Product Size Changeover
Quickly adapt automated lines to different product lengths by rotating the rear adjuster screw to shift the stroke end position.
Long-Stroke Positioning
Leverage the 950mm travel for extended reach operations while maintaining the ability to trim the stroke by up to 100mm for setup flexibility.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX950-100 the Right Cylinder?
Choose this 80mm bore when you need more thrust than a 63mm cylinder (which provides 1559N push at 0.5MPa) but want to avoid the larger footprint of a 100mm bore. The adjustable stroke is perfect for machine setups requiring variable end-stops or product-size changeovers. When matching ISO 15552 replacements, verify the 950mm stroke, 100mm adjuster, PT G3/8 port, and your required mounting style.
Note that the rear adjuster acts strictly as a mechanical stop and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider an AirTAC SAIL or BSAI cylinder. The available mounting set for this series includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Operating speed for this bore is 30-800mm/s.

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 SAIJ80AX950-100 FAQ
It features a rear mechanical stopper that allows you to shorten the effective stroke by up to 100mm. This creates a usable travel window of 850-950mm, letting you trim the retract position without replacing the cylinder.
At 0.5MPa operating pressure, it provides 2513N of push force and 2268N of pull force. It can reach a maximum push force of 4523N at 0.9MPa.
