About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX100-75S
The AirTAC SAIJ100X100-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 25-100 mm. The extruded aluminum barrel features sensor grooves on both sides, and this -S variant includes a magnet for direct compatibility with CMSE reed and DMSE electronic solid-state switches.
This model features a SUS420J2 stainless steel rod (material code A) and PT tapered port threads. The generous 75 mm adjustment range allows you to dial in the exact retract end-position during commissioning without adding external stops. Remember that the rear adjuster acts purely as a travel stop and 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 SAIJ100AX100-75S Is Used
Product Changeovers
Quickly reconfigure the retract distance by up to 75 mm when switching between different product sizes on a packaging line.
Machine Setup
Fine-tune the exact end-position during commissioning without machining custom spacers or bolting on external hard stops.
Variable End Stops
Handle heavy pressing or lifting tasks up to 3927 N while maintaining the flexibility to adjust the stroke window from 25 to 100 mm.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX100-75S the Right Cylinder?
The adjustable stroke is perfect for machines requiring frequent product-size changeovers, letting you fine-tune the retract distance on the fly rather than swapping out a fixed-stroke SAI cylinder. If your application requires holding a load in place without continuous air pressure, you will need an external rod lock or a different AirTAC series like the SAIL or BSAI.
When replacing an ISO 15552 cylinder, verify the 100 mm bore, 100 mm stroke, 75 mm adjustment range, G3/8 port, and the -S magnet requirement. Mounting options for this SAIJ series include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the stroke is under 300 mm, side-load stress on the 25 mm rod is manageable, but always ensure proper alignment to maximize seal life.
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 SAIJ100AX100-75S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from its nominal 100 mm down to as little as 25 mm. It only sets the travel end and does not lock the load without live air pressure.
