About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-50S
The AirTAC SAIJ100X80-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 80mm stroke that can be fine-tuned down by up to 50mm, yielding a highly flexible 30-80mm usable travel window. Delivering 3927N of push force at 0.5MPa, it handles substantial workloads while allowing precise end-position calibration during commissioning.
This model includes a built-in magnet for CMSE reed and DMSE electronic sensors, which seat directly into the dual-side extruded aluminum barrel grooves. The rear adjuster functions strictly as a mechanical stop to set deceleration and travel limits, not as a load-holding lock. For position retention without live air pressure, an external rod lock or AirTAC SAIL and BSAI series cylinders are required.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-50S Is Used
Precision Forming Stops
Dial in the exact 30-80mm retract position for metal forming or bending operations, allowing rapid accommodation of varying material thicknesses without changing cylinders.
Machine Changeover
Quickly adjust the end-stop during product size transitions on a packaging line, using the 50mm rear screw to fine-tune the stroke window for new carton dimensions.
Clamp Position Tuning
Set precise clamping travel for heavy assembly fixtures, leveraging the 3927N push force at 0.5MPa while adjusting the stopper to prevent over-travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-50S the Right Cylinder?
Choose this 100mm bore when an application demands high thrust—such as 3927N push at 0.5MPa—but requires on-the-fly end-stop tuning. If the workload drops, stepping down to an 80mm bore yields 2513N push force, whereas moving up to a 125mm bore provides 6136N. The SAIJ100X80-50-S is selected over a fixed-stroke SAI specifically to dial in exact retract positions during machine setup or product changeover without adding external stops.
When matching ISO 15552 replacements, verify the 100mm bore, 80mm nominal stroke, 50mm adjustment range, G1/2 PT port, and the -S magnet option. It supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 80mm stroke is short, side-loading is minimal, but ensure the M20x1.5 rod thread is properly aligned to prevent binding.

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 SAIJ100 Adjustable Cylinder SAIJ100X80-50S FAQ
At 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At the maximum 1.0MPa, the push force reaches 801kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 80mm nominal stroke by up to 50mm. This creates a 30-80mm usable travel window for fine-tuning end positions at commissioning without needing external stops.
