About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-40
The AirTAC SAIJ80X195-40 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N push force at 0.5 MPa and features a 195mm nominal stroke that can be dialed back by up to 40mm, yielding a precise 155-195mm usable travel window for on-the-fly positioning.
This extruded aluminum profile cylinder omits the FB, CA, CB, and CR mounts, utilizing a focused mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The 25mm carbon steel rod and M20x1.5 thread provide excellent structural integrity, while the PT tapered port ensures a reliable pneumatic seal.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-40 Is Used
Product Changeover
Dial in the 155-195mm travel window during packaging line format changes to accommodate different carton sizes without swapping cylinders.
Machine Setup
Fine-tune the retract end-position during initial commissioning to perfect the seating force of a 2513N pressing operation.
Variable End Stops
Adjust the stroke on the fly for automated assembly stations that need to test multiple part heights without adding external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-40 the Right Cylinder?
Select this 80mm bore when an application requires substantial thrust, such as the 2268N pull force at 0.5 MPa, but demands a variable end-stop for product changeovers. If your setup requires less force, stepping down to a 63mm bore provides 1559N push force; if more is needed, a 100mm bore yields 3927N. Because the 195mm stroke approaches the threshold requiring external guidance, ensure your mechanical layout supports the load to prevent excessive side-loading on the rod.
The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider an AirTAC SAIL or BSAI cylinder. To replace an ISO 15552 cylinder, match the 80mm bore, 195mm stroke, 40mm adjustment, PT port, and mounting hardware. Since no magnet is specified, this unit will not work with CMSE or DMSE sensors.
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 SAIJ80X195-40 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 40mm from the 195mm nominal length, creating a 155-195mm usable travel window. It functions as a mechanical stop and does not lock the load without continuous air pressure.
