About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX185-10S
The AirTAC SAIJ100X185-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 175-185mm usable travel window, letting you trim the effective stroke by up to 10mm during commissioning without adding external stops.
This variant features a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel integrates standard sensor grooves compatible with AirTAC CMSE reed and DMSE electronic switches. It uses a G1/2 port and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX185-10S Is Used
Machine Setup & Changeover
Dial in the 10mm adjustment window during line changeovers to perfectly tune the end-of-stroke position for new product dimensions without swapping hardware.
Variable End-Stop Tuning
Fine-tune the retract stroke within the 175-185mm range to compensate for mechanical wear or to optimize clamping force on heavy assemblies.
Heavy-Duty Positioning
Leverage the 100mm bore delivering up to 801 kgf max thrust for robust pushing and pressing operations that require precise, adjustable travel limits.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX185-10S the Right Cylinder?
The adjustable stroke is ideal for product changeovers where exact end-position tuning is necessary, avoiding the need to swap out a fixed-stroke SAI cylinder.
Remember that the rear adjuster functions purely as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series. This SAIJ100X185-10-S is dimensionally interchangeable per ISO 15552 and is configured with PT tapered ports, a 25mm rod with an M20x1.5 thread, and the -S magnet option. Operating speed is 30-800 mm/s.
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 SAIJ100AX185-10S FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the nominal 185mm stroke by up to 10mm, creating a usable travel window of 175-185mm. It only sets the travel end and does not lock or hold the load without continuous air pressure.
At 0.9 MPa, the push force increases to 7068N, with a maximum thrust of 801 kgf at 1.0 MPa.
