About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-100
The AirTAC SAIJ160X125-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 125 mm travel by up to 100 mm. This yields a highly flexible usable travel window of 25 to 125 mm, perfect for dialing in exact end positions during commissioning without swapping hardware. It delivers substantial thrust, pushing 10053 N and pulling 9425 N at 0.5 MPa.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The rear adjuster acts purely as a mechanical stop to set the retraction end-point; it does not hold the load without live air pressure. For position holding without continuous air, an external pilot-operated check valve or a related SAIL lock cylinder is required.

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 SAIJ160BX125-100 Is Used
Variable End-Stop Tuning
Ideal for heavy press applications where the exact bottoming position must be dialed in precisely within the 25 to 125 mm window during initial setup or product changeover.
Heavy Machinery Setup
Provides the high thrust needed for large forming machines while allowing technicians to adjust the retract distance on the fly without adding bulky external mechanical stops.
Product Size Changeover
Enables production lines to quickly adapt cylinder travel for different sized heavy components by simply turning the rear adjuster screw rather than replacing the entire cylinder.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-100 the Right Cylinder?
If your setup only needs a fixed 125 mm stroke without end-point tuning, a standard SAI cylinder simplifies the assembly.
Because the 125 mm stroke is relatively short for this large bore, side-load risks are minimal, but the heavy 40 mm rod and M36x2 thread handle robust mechanical stresses well. Ensure you specify PT ports and note that SAIJ supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) omitting FB, CA, CB, and CR options. As this unit lacks a magnet, position sensing requires external limit switches rather than embedded CMSE or DMSE sensors.
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 SAIJ160BX125-100 FAQ
At 0.7 MPa, the push force increases to 14074 N.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back from the 125 mm nominal length by up to 100 mm. This creates a usable travel window of 25 to 125 mm, allowing precise end-position tuning without changing the cylinder.
