About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-10S
The AirTAC SAIJ80X115-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 105-115 mm, letting you dial in the exact end position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches.
In the 80 mm bore class, this single-rod actuator generates 2513 N of push force and 2268 N of pull force at 0.5 MPa. It uses a 25 mm carbon steel rod and a PT tapered port. The variable air cushions at both ends absorb kinetic energy, but the rear adjuster acts only as a travel stop—it will not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-10S Is Used
Machine Changeover
Quickly fine-tune the 105-115 mm retract stop during product size changes on a packaging line without swapping the actuator.
End-Position Trimming
Dial in the exact retraction point during machine commissioning to avoid adding external mechanical stopper blocks.
Clamp Positioning
Set a precise clamping depth using the rear screw, relying on the 2513 N push force to secure the workpiece.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-10S the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI when you need on-the-fly end-position tuning for product changeovers. If your application requires less force, stepping down to a 63 mm bore yields 1559 N of push force at 0.5 MPa. For higher force, a 100 mm bore provides 3927 N. The 25 mm rod and M20x1.5 thread handle high side loads, though any stroke over 300 mm would require an external guide. This cylinder uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. For load-holding without continuous air, select the SAIL or BSAI series instead.
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 SAIJ80X115-10S FAQ
At 0.5 MPa operating pressure, the 80 mm bore generates 2513 N of push force and 2268 N of pull force. It can reach up to 4523 N push force at its maximum 0.9 MPa pressure.
The rear adjuster screw lets you shorten the 115 mm nominal stroke by up to 10 mm, creating a 105-115 mm usable travel window. This stopper decelerates the travel end but does not lock the load without live air.
