About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX100-75
The AirTAC SAIJ100X100-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 25 to 100 mm, allowing you to dial back the nominal 100 mm stroke by up to 75 mm during commissioning.
This specific SKU features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic switches if a magnet is added later. Mounting options cover Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR.

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 SAIJ100AX100-75 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance from 25 to 100 mm on the fly, perfect for testing actuation depths on new product prototypes without machining custom spacers.
Machine Changeover
Rapidly adjust the stroke window up to 75 mm when switching a packaging line to a different carton size, saving downtime on physical cylinder swaps.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX100-75 the Right Cylinder?
The rear adjustment screw acts purely as a mechanical stop to fine-tune travel without swapping cylinders or adding external stops. It does not hold the load without live air pressure; for true load-holding, select the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 100 mm nominal stroke, 75 mm adjuster, PT G1/2 port, and your required mounting. The 25 mm rod and M20x1.5 thread handle high side loads, but for any stroke approaching 300 mm or beyond, an external guide rail is recommended to prevent rod binding.
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 SAIJ100AX100-75 FAQ
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective travel from the 100 mm nominal stroke down to a minimum of 25 mm. This creates a 25-100 mm adjustable window for fine-tuning end positions at commissioning.
