About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-100
The AirTAC SAIJ100X800-100 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, allowing you to dial back the nominal 800 mm travel by up to 100 mm. This creates a precise 700-800 mm usable window for fine end-position tuning at commissioning without bolting on external stops.
This unit features a SUS420J2 stainless steel rod for enhanced corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU ships without a magnet. The rear adjuster acts strictly as a travel stop to set deceleration endpoints, 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 SAIJ100AX800-100 Is Used
Variable End-Stop Positioning
Dial in the exact 700-800 mm extended position during machine commissioning to accommodate different product lengths without changing hardware.
Product Size Changeover
Quickly adjust the stroke window on packaging lines when switching between carton sizes, ensuring precise stops for varying downstream processes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-100 the Right Cylinder?
If you need less force, stepping down to an 80 mm bore yields 4523 N at 0.9 MPa, while a 125 mm bore provides 11045 N for heavier loads. The adjustable stroke is ideal for machine setups where the exact extended position varies, avoiding the need to swap a fixed-stroke SAI cylinder.
For an exact ISO 15552 replacement match, configure with a 100 mm bore, 800 mm stroke, 100 mm adjustment, PT G1/2 ports, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting. At 800 mm of travel, the long unsupported stroke requires an external guide to prevent side-loading damage. Because the rear adjuster is a stop and not a lock, use a SAIL or BSAI cylinder if you need to hold the load safely without live air pressure.
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 SAIJ100AX800-100 FAQ
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective travel from the nominal 800 mm down to 700 mm. This provides a 700-800 mm adjustable window for fine-tuning the retract end position during setup.
