About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX450-20
The AirTAC SAIJ100X450-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, letting you dial back the 450 mm nominal travel by up to 20 mm. This creates a precise 430-450 mm usable travel window for fine end-position tuning during commissioning without adding external stops. It delivers substantial thrust, pushing 5497 N at 0.7 MPa, making it suitable for heavy-duty positioning tasks.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, though this unit lacks the internal magnet required for CMSE or DMSE switches. The rear adjuster acts purely as a mechanical stop to set deceleration, 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 SAIJ100AX450-20 Is Used
Heavy Press Tuning
Dial in the exact 430-450 mm end-stop during heavy press setup to accommodate material thickness variations without swapping cylinders.
Product Changeover
Quickly adjust the travel limit on a packaging line to handle different carton sizes, using the rear screw for rapid format changes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX450-20 the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, providing flexibility that a fixed-stroke SAI cylinder cannot match. Because the stroke is 450 mm, an external guide is recommended to prevent excessive side-loading on the long unsupported rod.
When ordering, confirm the 100 mm bore, 450 mm stroke, 20 mm adjustment, PT ports, and the SUS420J2 rod material. It uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that a plain SAIJ does not hold its load without live air; for dead-end locking, select an SAIL or BSAI cylinder instead.
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 SAIJ100AX450-20 FAQ
The rear adjuster screw lets you mechanically shorten the 450 mm nominal stroke by up to 20 mm, creating a 430-450 mm usable travel window. It functions as a hard stop to tune the end position and does not lock the load without live air pressure.
