Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-10
The AirTAC SAIJ100 Adjustable Cylinder SAIJ100AX300-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 300mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-10
Its 300 mm nominal stroke can be dialed back by up to 10 mm, creating a precise 290-300 mm usable travel window for fine-tuning at commissioning. The extruded aluminum barrel features sensor grooves on both sides, and this configuration uses a SUS420J2 stainless steel rod for enhanced corrosion resistance.
This model incorporates a PT tapered port thread (G1/2) and provides variable air cushions at both ends to manage kinetic energy. The rear adjuster acts strictly as a travel stop to set the retraction end position, meaning it will not hold a load without live air pressure. For load-holding requirements without continuous air, consider an external rod lock or related types like the SAIL or BSAI.

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 SAIJ100AX300-10 Is Used
Product Changeover
Dial in the 290-300 mm travel window during production line size changes to accommodate varying package lengths without replacing hardware.
Machine Setup
Fine-tune the exact end-stop position during equipment commissioning to prevent mechanical crashes and optimize tooling alignment.
Variable End Stops
Adjust the retraction point on the fly for sorting diverters that must handle different product dimensions on a single conveyor belt.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-10 the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers without swapping the entire cylinder for a fixed-stroke SAI variant. When replacing an ISO 15552 cylinder, match the 100 mm bore, 300 mm stroke, 10 mm adjustment, PT port, and mounting set.
Because this model features a 300 mm stroke, the 25 mm rod diameter should be paired with an external guide to prevent excessive side-loading on the piston. Note that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Without a magnet, this unit does not support CMSE or DMSE sensors.
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 SAIJ100AX300-10 FAQ
At 0.9 MPa, the push force increases to 7068N.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke by up to 10 mm, providing a usable travel window of 290-300 mm from the 300 mm nominal stroke. It only sets the travel end and does not lock the load without live air pressure.
