Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-75
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 80mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-75
The AirTAC SAIJ100X80-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 80 mm stroke back by up to 75 mm. This creates a highly flexible 5-80 mm usable travel window, letting you dial in the exact end position during commissioning without swapping out the cylinder or adding external stops. Built with a robust 25 mm carbon steel rod and M20x1.5 thread, it delivers 3927 N of push force at 0.5 MPa and 7068 N at 0.9 MPa.
Unlike fixed-stroke SAI variants, this adjustable model uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches if needed later. Remember that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-75 Is Used
Machine Setup & Changeover
Dial in the exact retract position within the 5-80 mm window during product line changeovers without disassembling the pneumatic setup.
Variable End-Stop Tuning
Fine-tune the end position during machine commissioning to accommodate mechanical tolerances or varying workpiece sizes.
Assembly Press Positioning
Leverage the 7068 N push force at 0.9 MPa to press components, using the rear stopper to set precise final depths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-75 the Right Cylinder?
Choose this 100 mm bore when you need substantial thrust—7068 N at 0.9 MPa—and the ability to fine-tune the retract end-stop on the fly. If your application requires less force, stepping down to an 80 mm bore yields 4523 N at 0.9 MPa, whereas moving up to a 125 mm bore provides 11045 N at the same pressure. The adjustable 5-80 mm travel window is perfect for product-size changeovers on a line. When replacing an ISO 15552 cylinder, match the 100 mm bore, 80 mm nominal stroke, 75 mm adjustment, G1/2 PT port, and mounting style. Because the stroke is under 300 mm, side-load concerns are minimal, but always ensure the 25 mm rod is properly guided for optimal seal life.
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 SAIJ100X80-75 FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as an external stopper that lets you shorten the 80 mm nominal stroke by up to 75 mm, creating a usable travel window of 5 to 80 mm. It sets the end position but does not lock the load without live air pressure.
