About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-75
The AirTAC SAIJ100X375-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 375 mm travel by up to 75 mm, creating a precise 300-375 mm usable window. This on-machine fine-tuning eliminates the need to swap cylinders or bolt on external stops during product changeovers.
The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It uses a PT tapered port thread and operates at speeds from 30 to 800 mm/s. Mounting options include the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster and air cushions only decelerate the load; they do not hold position 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 SAIJ100AX375-75 Is Used
Product Changeovers
Dial in the 300-375 mm travel window on the fly to accommodate different package lengths without changing the cylinder.
Machine Commissioning
Fine-tune the exact retract end-position during setup to perfect tooling alignment without adding external stoppers.
Variable End-Stop Forming
Adjust the stroke on heavy press equipment to handle varying material thicknesses within the same production line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-75 the Right Cylinder?
The 75 mm adjustment range is ideal for machinery requiring frequent product-size changeovers, letting you set variable end-stops during commissioning without replacing the actuator. Because the nominal stroke is 375 mm, an external guide rail is recommended to prevent excessive side-loading on the rod.
For a direct ISO 15552 dimensional interchangeability match, specify a 100 mm bore, 375 mm stroke, 75 mm adjustment, PT port thread, and the appropriate mounting bracket. Note that a plain SAIJ does not hold its load without live air; for fail-safe holding, 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 SAIJ100AX375-75 FAQ
At the maximum pressure of 1.0 MPa, the push force reaches 801 kgf.
The rear adjusting screw acts as a mechanical stop that trims the effective travel back from the 375 mm nominal stroke, giving you a usable 300-375 mm window. It sets the end position but does not lock or hold the load without continuous air pressure.
