About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-100S
The AirTAC SAIJ80X100-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 2513 N of push force at 0.5 MPa and features a 25 mm stainless steel (SUS304) rod. Because this specific SKU carries a 100 mm adjustment code on a 100 mm nominal stroke, you can dial the effective travel all the way down from 100 mm to a near-zero retracted position.
This wide 0-100 mm usable window is ideal for prototyping or highly variable product lines. The cylinder uses PT tapered ports (G3/8) and includes a magnet for CMSE and DMSE sensors. The rear screw acts purely as a mechanical stop to set the end position and must not be confused with a lock, as it cannot hold a load without continuous air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-100S Is Used
Product Changeovers
Dial the stroke from 0 to 100 mm on the fly to accommodate different package sizes on a packaging line without changing the cylinder.
Prototype Positioning
Perfect for dialing in the exact extension distance during machine commissioning before finalizing fixed mechanical stops.
Variable End Stops
Provides a mechanical stop to tune the retract position for automated assembly equipment requiring frequent format adjustments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-100S the Right Cylinder?
Choose this 80 mm bore when you need substantial thrust, such as 2513 N push at 0.5 MPa, but require extreme flexibility in the end-stop position. If your application needs less force, stepping down to a 63 mm bore yields 1559 N. Selecting this adjustable SAIJ over a fixed-stroke SAI prevents the need to physically swap cylinders during machine changeovers or when finalizing a new product setup. To replace this cylinder with another ISO 15552 unit, match the 80 mm bore, 100 mm stroke, 100 mm adjustment, PT G3/8 port, and the -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80BX100-100S FAQ
At 0.5 MPa it provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa the push force increases to 3518 N.
The rear adjuster screw lets you trim the effective travel down from the 100 mm nominal stroke to 0 mm. It functions as an end-position stop and does not lock the load without live air pressure.
