About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-100S
The AirTAC SAIJ80X190-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 2513N push force at 0.5MPa and provides a usable travel window of 90 to 190mm, letting you dial back the nominal stroke by up to 100mm. This wide adjustment range is ideal for product changeovers where end-position tuning must happen quickly without swapping out the actuator.
Equipped with a magnetic piston for position sensing, it supports AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves on the extruded aluminum barrel. It features a 25mm carbon steel rod with an M20x1.5 thread, offering high side-load resilience, and uses PT tapered G3/8 ports. The variable air cushions at both ends decelerate the load, but remember the adjuster is a stop, not a lock; for load-holding without live air, consider the SAIL or BSAI series.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-100S Is Used
Product Changeover Setup
Leverage the 90-190mm travel window to quickly adapt end-stops for different sized parts on the same production line without physically replacing cylinders.
End-Position Trimming
Fine-tune the retract stroke during commissioning using the rear adjuster screw to achieve exact positioning without adding external mechanical stops.
Heavy-Duty Forming
Utilize the 2513N push force at 0.5MPa for pressing and forming tasks, using the magnetic piston for end-of-stroke confirmation via DMSE sensors.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-100S the Right Cylinder?
Choose this 80mm bore actuator when your application requires substantial thrust but variable end-stops. If you need less force, stepping down to a 63mm bore yields 1559N push at 0.5MPa, whereas moving up to a 100mm bore provides 3927N. The 100mm adjustment range on this SKU allows extreme flexibility during machine setup, acting as a built-in external stop without the need for custom brackets. Because the stroke is 190mm, side-loading is moderate, but always ensure proper external guiding for heavy loads.
When specifying a replacement, match the 80mm bore, 190mm nominal stroke, 100mm adjustment, PT G3/8 port thread, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. It is dimensionally interchangeable per ISO 15552, operating at 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 SAIJ80X190-100S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 100mm, providing a usable travel window of 90 to 190mm. It sets the end-position but does not lock or hold the load without live air pressure.
At 0.5MPa, it provides 2513N of push force and 2268N of pull force. At 0.7MPa, the push force increases to 3518N.
