About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-75
The AirTAC SAIJ100X350-75 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 350 mm stroke that can be trimmed back by up to 75 mm, yielding a precise 275-350 mm usable travel window for fine-tuning end positions at commissioning.
This extruded aluminum barrel design includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a mechanical stop to set the travel end and relies on the integrated air cushions for deceleration; it does not hold the load without live air pressure. It supports a speed range of 30-800 mm/s and uses a PT G1/2 port.

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 SAIJ100AX350-75 Is Used
Variable End-Stop Setup
Dial in the exact 275-350 mm travel distance during machine commissioning without replacing the entire cylinder or adding external shims.
Product Changeover
Quickly adjust the retract stroke to accommodate different product sizes on a single production line, minimizing downtime between runs.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-75 the Right Cylinder?
The adjustable stroke is ideal for product changeovers and variable end-stops, eliminating the need to swap cylinders or bolt on external stops during machine setup. For a direct ISO 15552 replacement match, specify a 100 mm bore, 350 mm stroke, 75 mm adjustment, PT G1/2 port, and SUS420J2 (A) rod material. Note that SAIJ uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Because the 350 mm stroke is relatively long, ensure you use an external guide to prevent rod sagging and excessive side-load wear.

- ✓ 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 SAIJ100AX350-75 FAQ
At 0.7 MPa, the push force increases to 5497 N.
A rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective travel from the 350 mm nominal stroke down to as little as 275 mm. This provides a 275-350 mm adjustable window for precise end-position tuning without swapping cylinders.
