About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-30
The AirTAC SAIJ100X650-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 650 mm stroke that can be fine-tuned backward by up to 30 mm, creating a precise 620-650 mm usable travel window.
This variant uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and is fitted with PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning CMSE or DMSE electronic sensors cannot be used without modification. The rear adjuster acts purely as a travel stop for product changeovers, not as a load-holding lock.

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 SAIJ100AX650-30 Is Used
Variable End-Stop Forming
Dial in the exact 620-650 mm retraction point during heavy-duty forming or pressing tasks, allowing quick adaptation to different material thicknesses without changing the cylinder.
Product-Size Changeovers
Adjust the rear stopper on the fly to accommodate varying package lengths on a packaging line, ensuring precise positioning without external mechanical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-30 the Right Cylinder?
Select this 100 mm bore cylinder when an application demands high thrust alongside variable end-stop positioning. If 5497 N at 0.7 MPa is excessive, stepping down to an 80 mm bore yields 3518 N; if more force is required, a 125 mm bore provides 8590 N. The adjustable stroke is ideal for machine setups requiring frequent product-size changeovers, eliminating the need to swap out a fixed-stroke SAI cylinder.
Because the 650 mm stroke is relatively long, an external guide should be used to support the load and mitigate side-loading on the M20x1.5 rod thread. To match this ISO 15552 footprint, ensure your mounting choice falls within the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Remember that the rear adjuster and air cushions decelerate the load but do not hold it without live air; for fail-safe load holding, consider an external rod lock or the 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 SAIJ100AX650-30 FAQ
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 650 mm down to 620 mm. This enables fine-tuning of the end position during setup without replacing the cylinder.
