About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-100
The AirTAC SAIJ80X190-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 2513N of push force at 0.5 MPa and provides a usable travel window of 90-190mm, letting you dial back the nominal 190mm stroke by up to 100mm during machine setup. This wide adjustment range is perfect for product changeovers without swapping hardware.
Equipped with a 25mm carbon steel rod and an M20x1.5 thread, it handles demanding side loads, while the G3/8 PT port ensures efficient air flow. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-100 Is Used
Product Changeover
Quickly shift the end-of-stroke position by up to 100mm when adapting machinery to a new product size, minimizing downtime.
Prototype Setup
Fine-tune the exact 90-190mm travel distance during commissioning to find the optimal contact point without machining new spacers.
Variable End Stops
Use the rear screw to establish precise retract positions on automated lines where multiple stop lengths are required.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-100 the Right Cylinder?
Choose this 80mm bore when a 50mm bore (982N push at 0.5 MPa) lacks thrust but a 100mm bore is physically too large. The 100mm adjustment window is ideal for prototyping or lines running multiple product sizes, acting as a variable end-stop rather than requiring custom fixed-stroke SAI cylinders. For any stroke near or over 300mm, always use an external guide to prevent rod binding, though this 190mm unit is compact.
Remember that the rear adjuster is a travel stop, not a lock; the SAIJ80X190-100 cannot hold a load without live air. For pneumatic load-holding, select an SAIL or BSAI cylinder. This PT-port model is dimensionally interchangeable per ISO 15552.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ80X190-100 FAQ
At 0.5 MPa, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 190mm down to as little as 90mm, giving a 90-190mm usable window. It acts as a mechanical stop and does not lock the load without air pressure.
