About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX185-100
The AirTAC SAIJ100X185-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel. With a 185mm nominal stroke and a 100mm adjustment range, it provides a wide 85-185mm usable window for precise end-position tuning at commissioning.
This variant uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear screw acts purely as a mechanical stop to decelerate and set the travel end, meaning it 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 SAIJ100AX185-100 Is Used
Machine Changeover
Dial in the 85-185mm travel window during product format changes to set new end positions rapidly without disassembling the actuator.
End-Position Tuning
Fine-tune the exact retract stop during commissioning to compensate for mechanical tolerance buildup in heavy-duty tooling.
Variable End Stops
Provide adjustable physical stops for assembly presses that need to handle multiple part sizes on the same line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX185-100 the Right Cylinder?
Choose this adjustable model when your machine setup requires variable end-stops or frequent product-size changeovers without physically swapping cylinders or adding external stopper blocks. For load-holding requirements without continuous air pressure, a standard SAIJ is insufficient; consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 100mm bore, 185mm stroke, 100mm adjustment, G1/2 port, and your required mounting accessory. The SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Since the 25mm rod and M20x1.5 thread handle high side loads, ensure proper external guiding for optimal performance.
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 SAIJ100AX185-100 FAQ
The rear adjuster screw lets you shorten the 185mm nominal stroke by up to 100mm, creating an 85-185mm usable travel window. The adjuster functions as a mechanical stop to set the end position, not a lock, and does not hold the load without live air.
