About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-40
The AirTAC SAIJ100X650-40 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 3927N of push force at 0.5 MPa, making it suitable for heavy-duty positioning. By turning the external stopper screw, you can trim the effective travel within a 610 to 650 mm window, which is ideal for fine-tuning end positions during commissioning without swapping out the entire actuator.
This 100 mm bore unit features a 25 mm carbon steel rod and a PT G1/2 port. It includes adjustable air cushions at both ends to absorb kinetic energy, but note that the rear adjuster acts strictly as a travel stop, not a load-holding lock. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic switches if needed.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-40 Is Used
Product Changeover
Dial in the 610-650 mm travel window on the fly when switching product sizes on a packaging line, avoiding mechanical teardown.
Heavy Press Positioning
Utilize the 3927N push force at 0.5 MPa to move heavy jigs, relying on the rear stopper to set the exact lower dead center.
Long-Stroke Assembly
Drive components over a 650 mm span while using the 40 mm adjustment range to compensate for cumulative machine tolerances.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-40 the Right Cylinder?
Select this 100 mm bore actuator when your application requires high thrust, specifically 3927N push or 3681N pull at 0.5 MPa. If your setup demands less force, stepping down to an 80 mm bore provides 2513N push force, whereas moving up to a 125 mm bore yields 6136N. The adjustable stroke is particularly valuable for product changeovers on a line, allowing you to dial in a new end-stop quickly instead of installing external shims or a fixed-stroke SAI cylinder.
When integrating this ISO 15552 interchangeable cylinder, verify your mounting choice from the available SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, noting that FB, CA, CB, and CR brackets are omitted. Because the 650 mm stroke is long, the 25 mm rod requires external guide rails to prevent excessive side-loading and premature seal wear. Finally, remember that a plain SAIJ does not hold position without live air; for fail-safe load holding, consider an external rod lock or the AirTAC SAIL series.
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 SAIJ100X650-40 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 650 mm nominal stroke by up to 40 mm. This creates a usable travel window of 610 to 650 mm for fine-tuning the retract end position.
