About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-50
The AirTAC SAIJ100X300-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 250-300mm usable travel window from its 300mm nominal stroke. The barrel is extruded aluminum with sensor grooves on both sides, and this specific configuration uses a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance.
Instead of swapping cylinders during product changeover, the external stopper screw allows you to fine-tune the retract end position on the fly. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Note that the adjuster acts only as a travel stop and deceleration aid alongside the air cushions—it does not 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 SAIJ100AX300-50 Is Used
Product Changeover
Dial in the 250-300mm travel window during format changes without swapping the cylinder or bolting on external stops.
End-Position Tuning
Fine-tune the retract stop at commissioning to perfect machine timing using the rear adjustment screw.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-50 the Right Cylinder?
The adjustable stroke is ideal for machine setup and product-size changes, preventing the need to physically swap out a fixed-stroke SAI cylinder. For true load-holding without live air, consider the SAIL or BSAI series, as this adjuster is not a lock.
When replacing an ISO 15552 cylinder, match the 100mm bore, 300mm stroke, 50mm adjustment range, and PT G1/2 port. Because the stroke is 300mm, an external guide rail is recommended to prevent excessive side-loading on the 25mm rod. This unit lacks a magnet, so if position sensing is needed, select an -S variant to use CMSE reed or DMSE electronic switches.
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 SAIJ100AX300-50 FAQ
At a maximum 1.0 MPa, the push force reaches 7068N.
The rear adjuster screw lets you trim the effective stroke by up to 50mm, creating a 250-300mm usable travel window from the 300mm nominal stroke. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air.
