About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-50S
The AirTAC SAIJ80X130-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 2513N of push force at 0.5MPa and features a 25mm carbon steel rod with an M20x1.5 thread. By integrating a -S magnet, this unit directly supports AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side extruded barrel grooves.
With a 130mm nominal stroke and a 50mm adjustment range, you gain an 80-130mm usable travel window. This built-in rear stopper allows precise end-position tuning during commissioning without swapping hardware. The adjuster acts purely as a travel stop and works alongside variable air cushions at both ends to control deceleration, but it does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-50S Is Used
Product Changeovers
Dial in the 80-130mm travel window during format size shifts on packaging lines without bolting on external stops.
Machine Setup
Fine-tune the retract end-position at commissioning to perfectly seat components using the 50mm rear adjustment screw.
Variable End Stops
Accommodate multiple part lengths on a single conveyor station by adjusting the stroke limit on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-50S the Right Cylinder?
Select this 80mm bore when an application requires moderate thrust and on-the-fly stroke trimming, stepping up from a 63mm bore that provides 1559N at 0.5MPa. The 50mm adjustment window is ideal for product changeovers on a packaging line, replacing the need for fixed-stroke SAI cylinders when end-stop positions vary. For any stroke at or above 300mm, you would need an external guide to prevent side-loading, though this 130mm unit handles its 25mm rod thread robustly. To match this ISO 15552 footprint exactly, specify the 80mm bore, 130mm stroke, PT tapered port thread, and the -S magnet option.
Mounting choices include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles. Because the rear adjuster is a stop and not a locking mechanism, select a SAIL or BSAI cylinder if your workflow demands true load-holding without continuous air supply.
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 SAIJ80X130-50S FAQ
At 0.5MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7MPa, the push force increases to 3518N.
The rear adjuster screw allows you to trim the effective travel back by up to 50mm from the 130mm nominal stroke, creating an 80-130mm usable window. It acts as a physical stop to set the end position and does not lock the load without live air.
