About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-30
The AirTAC SAIJ100X175-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 175 mm stroke that can be dialed back by up to 30 mm, creating a precise 145-175 mm usable travel window for commissioning flexibility.
This model uses a SUS420J2 stainless steel rod (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 adjuster acts as a travel stop to fine-tune the end position, but it does not lock 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 SAIJ100AX175-30 Is Used
Product Changeover Stops
Dial in the 145-175 mm travel window during production line size changes to set new end positions without adding external mechanical stops.
Commissioning Fine-Tuning
Trim the rear adjuster up to 30 mm to perfectly dial in the final resting position of heavy 3927 N loads during initial machine setup.
Heavy Assembly Positioning
Leverage the robust 100 mm bore and SUS420J2 stainless rod to move heavy jigs into place, relying on the stopper for precise physical alignment.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-30 the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust, stepping up from a 63 mm bore that offers 1559 N at 0.5 MPa. The adjustable stroke is ideal for machine setups requiring variable end stops or product changeovers, allowing you to fine-tune the travel window without swapping out a fixed-stroke SAI cylinder. To match this ISO 15552 interchangeable cylinder, specify the 100 mm bore, 175 mm stroke, 30 mm adjustment, PT G1/2 port, and your required mounting from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the stroke is 175 mm, ensure proper external guiding to prevent excessive rod side-loading. Remember that the rear adjuster and air cushions only decelerate the travel end; for true load-holding without live air, select an SAIL lock or BSAI clamp-lock cylinder 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 SAIJ100AX175-30 FAQ
The rear adjuster acts as an external stopper that lets you shorten the effective travel from the nominal 175 mm down to 145 mm. It decelerates the end position but does not lock the load without live air.
