About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X140-10S
The AirTAC SAIJ80X140-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 130 to 140 mm usable travel window, allowing you to dial back the nominal 140 mm stroke by up to 10 mm during machine setup. Built with an extruded aluminum barrel and a carbon steel piston rod, it delivers 2513 N of push force at 0.5 MPa.
This model includes a magnetic piston (-S) for position sensing and uses PT tapered port threads. The integrated air cushions at both ends manage end-of-stroke deceleration, while the rear adjuster acts purely as a mechanical stop to set the exact retract position without needing external stops.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X140-10S Is Used
Machine Commissioning
Dial in the exact 130-140 mm retract position during initial machine setup without machining custom spacers or adding external stopper blocks.
Product Changeover
Quickly adjust the end-of-stroke stop on packaging lines when switching to a slightly different product size that needs precise positioning.
Heavy Clamping
Leverage the 2513 N push force at 0.5 MPa to secure heavy workpieces, using the 10 mm adjuster to set the exact clamping depth.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X140-10S the Right Cylinder?
Choose this 80 mm bore when your application requires substantial thrust, offering 2513 N push and 2268 N pull force at 0.5 MPa. If your setup demands less force, stepping down to a 63 mm bore yields 1559 N, but this SAIJ80X140-10-S is ideal for heavier payloads. The 10 mm adjustment range is perfect for fine-tuning end positions at commissioning rather than swapping a fixed-stroke SAI cylinder.
Because it includes a magnetic piston, this unit works seamlessly with AirTAC CMSE reed and DMSE solid-state sensors fitted into the barrel's dual sensor grooves. Remember that the rear adjuster and air cushions only decelerate the load; they do not hold position without live air pressure. For load-holding without continuous air, consider an external rod lock or the SAIL series. The mounting options include 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 SAIJ80X140-10S FAQ
The rear adjuster screw lets you mechanically shorten the stroke by up to 10 mm, creating a 130-140 mm usable travel window. It acts as a hard stop for the retract position, allowing fine-tuning during commissioning without changing the cylinder itself.
At a 0.5 MPa operating pressure, the SAIJ80X140-10-S provides 2513 N of push force and 2268 N of pull force. It can deliver up to 4523 N of push force at 0.9 MPa.
