About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX60-20
The AirTAC SAIJ100X60-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the effective travel by up to 20 mm. With a 60 mm nominal stroke, this configuration yields a highly versatile 40-60 mm usable travel window, ideal for fine-tuning end positions during machine commissioning or product changeovers without swapping out the hardware. It features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and utilizes PT tapered port threads.
The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches, though this specific SKU is built without a magnet. The rear adjuster acts purely as a mechanical stop to set the travel end and deceleration point; it does not lock or hold the load without live air pressure. For applications requiring true position holding, consider the SAIL or BSAI series instead.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX60-20 Is Used
Machine Changeover
Rapidly adjust the end-of-stroke position from 60 mm down to 40 mm during product size changeovers on a packaging line without disassembling the cylinder mounting.
End-Position Tuning
Fine-tune the final resting position of a high-force press or clamping mechanism during commissioning, ensuring precise alignment without adding external mechanical stops.
Variable End Stops
Accommodate slight dimensional variations in incoming workpieces by dialing in the exact clamping depth required for each batch, maximizing process control.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX60-20 the Right Cylinder?
Select this 100 mm bore cylinder when your process demands high force—stepping down to an 80 mm bore drops the 0.5 MPa push force to 2513 N, which may be insufficient for heavy actuation tasks. The SAIJ100X60-20 is specifically chosen over a fixed-stroke SAI model when a variable end-stop is required, allowing you to trim the stroke from 60 mm down to 40 mm to accommodate slight variations in product dimensions on a production line. Because the stroke is relatively short, external side-load guides are less critical here, but the robust 25 mm rod and M20x1.5 thread handle substantial mechanical stress.
When replacing an ISO 15552 cylinder, verify the 100 mm bore, 60 mm nominal stroke, 20 mm adjustment range, G1/2 port size, and PT thread type. This SAIJ model supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. If your fixture relies on rear pivot or trunnion mounting, you will need a different cylinder type or an external bracket.

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 SAIJ100AX60-20 FAQ
The cylinder has a 60 mm nominal stroke, but the external rear adjusting screw allows you to shorten the effective travel by up to 20 mm. This creates a 40-60 mm usable travel window, meaning you can set the retract end-position anywhere within that range without modifying the cylinder itself.
