About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-20
The AirTAC SAIJ100X80-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. It features a carbon steel piston rod and PT tapered ports. By turning the external rear screw, you can trim the effective travel within a 60-80mm usable window, providing exact end-position tuning without swapping hardware.
This adjustable stopper is ideal for product changeovers on the line, but it acts strictly as a travel stop and does not hold the load without live air. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-20 Is Used
End-Stop Tuning
Dial in the exact 60-80mm retraction point during machine setup to perfect product seating without machining new hard stops.
Product Changeover
Quickly adjust the rear travel screw by up to 20mm to accommodate minor variations in part sizes on the production line.
Heavy Forming
Leverage the 7068N push force at 0.9MPa for pressing operations while fine-tuning the bottoming position on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-20 the Right Cylinder?
Choose this 100mm bore when you need 3927N push force at 0.5MPa, or step down to the 80mm bore if 2513N is sufficient. The 20mm adjustment window is perfect for dialing in exact retraction during commissioning, avoiding the need to bolt on external stops. For any application requiring 300mm or more of stroke, always use an external guide to support the load.
To match an ISO 15552 replacement, verify the 100mm bore, 80mm stroke, 20mm adjustment, PT ports, and the required mounting bracket. If position holding without live air pressure is required, look instead to the SAIL or BSAI locking cylinder series, as this adjuster is not a brake.
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 SAIJ100X80-20 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 80mm stroke by up to 20mm. This creates a 60-80mm usable travel window for fine-tuning the end position at commissioning.
At 0.5 MPa operating pressure, it provides 3927N of push force and 3681N of pull force. At 0.9 MPa, the push force increases to 7068N.
