About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX55-10
The AirTAC SAIJ100X55-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 45 to 55 mm, allowing you to dial back the nominal 55 mm stroke by up to 10 mm during machine commissioning. This fine-tuning capability eliminates the need to swap the cylinder or bolt on external stops when positioning a load.
This SKU is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a PT tapered port thread. The extruded aluminum barrel features sensor grooves on both sides for direct mounting of AirTAC CMSE reed or DMSE solid-state switches. It uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

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 SAIJ100BX55-10 Is Used
End-Position Tuning
Dial in the exact 45-55 mm retract position during machine setup without changing out the entire cylinder assembly.
Product Changeover
Quickly adapt the stroke limit on packaging lines when switching to a different product size or thickness.
Machining Clamps
Use the precise stroke window to position clamping forces accurately, ensuring parts are held securely without overtravel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX55-10 the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI cylinder when your application requires variable end-stops or frequent product-size changeovers. The 10 mm adjustment window lets you refine the retract position on the fly. For higher thrust, a bore 125 provides 6136 N.
When matching an ISO 15552 replacement, verify the 100 mm bore, 55 mm stroke, 10 mm adjustment range, PT G1/2 port, and the correct mounting bracket. Because the stroke is under 300 mm, side-load stress on the 25 mm rod is manageable without an external guide. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding, use an external rod lock or consider the SAIL or BSAI series.
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 SAIJ100BX55-10 FAQ
At the maximum pressure of 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 10 mm. This creates a usable travel window of 45 to 55 mm, allowing you to fine-tune the end position without replacing the cylinder.
