About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-10S
The AirTAC SAIJ100X550-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 550 mm stroke with an integrated stopper that allows you to dial back the effective travel by up to 10 mm, creating a precise 540-550 mm usable window. This fine-tuning capability at commissioning eliminates the need to swap cylinders or bolt on external stops when aligning end positions.
It features a SUS420J2 stainless steel rod for corrosion resistance and includes a magnet for position sensing with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjuster acts purely as a travel stop, not a load-holding lock.

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 SAIJ100AX550-10S Is Used
Machine Changeover
Dial in the 540-550 mm travel window during product size changes to perfectly align end positions without swapping physical cylinder hardware.
End-Stop Tuning
Use the 10 mm rear adjustment screw to fine-tune the retract end position during commissioning, absorbing mechanical tolerances in the fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX550-10S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires variable end-stops or product changeovers without mechanical rebuilds. If you need slightly less force, stepping down to a bore 80 cylinder yields 2513 N at 0.5 MPa; if your application demands heavier thrust, a bore 125 provides 6136 N. Because this is a 550 mm stroke, the 25 mm rod diameter and M20x1.5 thread handle significant side loads, but an external guide is recommended for long unsupported travels.
This SKU is dimensionally interchangeable per ISO 15552. To match this exact configuration, specify bore 100, 550 mm stroke, 10 mm adjustment, PT tapered port threads, and a magnet for sensors. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. For applications requiring the load to hold position without live air pressure, note that the rear adjuster and air cushions do not function as a brake; consider an external rod lock or AirTAC SAIL and BSAI series cylinders 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 SAIJ100AX550-10S FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a mechanical stop that lets you shorten the 550 mm nominal stroke by up to 10 mm, providing a 540-550 mm usable travel window. It sets the end position but does not hold the load without live air pressure.
