About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-50S
The AirTAC SAIJ100X300-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel back by up to 50 mm. This yields a usable 250-300 mm end-position window, letting you dial in the exact retract distance during commissioning without swapping out the physical actuator.
Built with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance, this model includes a magnet for position sensing. The extruded aluminum barrel features sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. It uses a G1/2 port and relies on adjustable air cushions at both ends to decelerate the load smoothly.

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 SAIJ100AX300-50S Is Used
Product Changeover
Dial in the retract position by up to 50 mm when switching product sizes on a packaging line, avoiding physical cylinder swaps.
End-Stop Tuning
Fine-tune the final end position during machine commissioning to hit exact 250-300 mm travel windows without external shims.
Variable Positioning
Act as an adjustable hard stop for automated tooling that requires slight stroke modifications between different operational recipes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-50S the Right Cylinder?
An adjustable stroke is ideal for machine changeovers where the exact end-stop varies by product size, saving the cost of external stops. For any 300 mm stroke, an external guide is recommended to manage side loads, as the 25 mm rod diameter handles only moderate lateral stress.
Remember that the rear adjuster is a hard stop, not a lock; a plain SAIJ cannot hold a load without live air pressure. For true fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. This SAIJ100X300-50-S is dimensionally interchangeable per ISO 15552, uses PT tapered port threads, and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mountings.
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 SAIJ100AX300-50S FAQ
The rear adjuster screw acts as a mechanical stop that shortens the 300 mm nominal stroke by up to 50 mm, giving a usable travel window of 250-300 mm. It is a travel stop, not a lock, and does not hold the load without live air pressure.
