About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-10
The AirTAC SAIJ100X80-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 3927N of push force at 0.5 MPa, utilizing a 25mm carbon steel piston rod and G1/2 PT ports. The integrated adjustment screw allows you to trim the nominal 80mm stroke back by up to 10mm, creating a precise 70-80mm usable travel window for exact end-position tuning during commissioning.
This adjustable feature eliminates the need to swap cylinders or bolt on external stops when dialing in a machine sequence. It supports a speed range of 30-800 mm/s and includes variable air cushions at both ends to decelerate the load smoothly. The extruded aluminum barrel provides sensor grooves on both sides for mounting CMSE reed or DMSE electronic sensors if a magnet is specified later.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-10 Is Used
Machine Changeover
Dial in the 70-80mm travel window during product size changeovers without physically swapping the actuator or adding external mechanical stops.
End-Position Tuning
Fine-tune the exact retraction point during machine commissioning to perfect a gripping or pressing sequence on the assembly line.
Assembly Pressing
Leverage the 3927N push force at 0.5 MPa for pressing bearings or pins, using the adjuster to set a precise, repeatable bottoming depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-10 the Right Cylinder?
Select this 100mm bore when an application requires higher thrust than the 80mm bore (which provides 2513N at 0.5 MPa) but does not warrant the larger 125mm frame. The SAIJ100X80-10 is chosen over a fixed SAI cylinder when a process demands a variable end-stop to accommodate minor product size changes or fine-tune a gripping distance. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for true load-holding without continuous air, consider the SAIL or BSAI series. It mounts via Basic, FA, LB, TC, FTC, TCM1, or TCM2 interfaces, omitting FB, CA, CB, and CR options.
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 SAIJ100 Adjustable Cylinder SAIJ100X80-10 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. It can reach up to 7068N of push force at 0.9 MPa.
The rear adjuster screw lets you shorten the nominal 80mm stroke by up to 10mm, providing a usable travel window of 70-80mm. This allows you to set the exact retraction end-position during setup without needing external stops.
