About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX100-20
The AirTAC SAIJ100X100-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates an 80-100 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This SKU uses a SUS420J2 stainless steel rod (option A) for superior corrosion resistance compared to standard carbon steel. It features PT tapered port threads (G1/2) and relies on variable air cushions at both ends to decelerate the load. The rear adjuster acts strictly as a travel stop for fine-tuning, not as a lock to hold the load without live air pressure.

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 SAIJ100AX100-20 Is Used
Machine Setup Tuning
Dial in the exact 80-100 mm travel during commissioning to perfect end positions without machining custom spacers.
Product Changeover
Quickly adjust the rear stop to accommodate varying package sizes on a single conveyor line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX100-20 the Right Cylinder?
An adjustable stroke is ideal for machine setups requiring exact end-position tuning during commissioning or product changeovers, eliminating the need to swap cylinders or bolt on external stops. For strokes of 300 mm or more, an external guide is recommended to manage side loads, though this 100 mm stroke is well within safe limits.
To match this ISO 15552 cylinder, specify: 100 mm bore, 100 mm stroke, 20 mm adjustment, PT G1/2 ports, and your required mounting option from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because no magnet is specified, position sensing requires adding a magnet or external sensors. If you need true load-holding without live air, consider the SAIL or BSAI series 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 SAIJ100AX100-20 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjusting screw acts as an external stopper, allowing you to shorten the effective travel from the nominal 100 mm down to 80 mm. This provides a flexible 80-100 mm window for fine-tuning the end position at commissioning.
