About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-100S
The AirTAC SAIJ160X125-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a massive 10053N pull force at 0.5 MPa. With its 125mm nominal stroke and a 100mm adjustment range, it provides a highly flexible 25-125mm usable travel window. This wide tuning capacity is perfect for equipment requiring frequent product size changeovers without swapping hardware.
Built as an extruded aluminum profile cylinder, it features a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port. The integrated magnet (-S) supports CMSE reed and DMSE electronic sensors housed in the dual-side sensor grooves. It uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 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 SAIJ160 Adjustable Cylinder SAIJ160BX125-100S Is Used
Product Changeovers
Leverage the 25-125mm travel window to rapidly adapt machinery for different product lengths without physically replacing the cylinder.
Commissioning Calibration
Fine-tune the retract end-position precisely during machine setup, preventing the need for external stopper blocks or custom spacers.
Heavy Forming Presses
Utilize the 10053N pull force to handle heavy stamping or forming tasks, adjusting the stroke depth on the fly for varied material thicknesses.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-100S the Right Cylinder?
Choose this 160mm bore when an 80mm bore (delivering 2268N pull at 0.5 MPa) cannot meet your thrust requirements, but avoid oversizing into a 200mm bore unless absolutely necessary. The 100mm adjustment range is ideal for dialing in exact end positions during commissioning, whereas a fixed SAI cylinder locks you into a single dimension. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air, so use a SAIL or BSAI cylinder if load-holding is required.
For an ISO 15552 replacement match, ensure you specify the 160mm bore, 125mm stroke, 100mm adjustment, PT port thread, SUS304 (B) rod material, and the -S magnet. Operating speed for this bore is 30-500mm/s. Because the 125mm stroke is relatively short for this large bore, side-load stress is minimal, but external guides are still recommended for heavy off-center loads.
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 SAIJ160 Adjustable Cylinder SAIJ160BX125-100S FAQ
The rear adjuster screw lets you trim the effective stroke back by up to 100mm from the 125mm nominal length, creating a 25-125mm usable travel window. It functions as a mechanical stop for end-position tuning and is not a locking device.
