About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-50S
The AirTAC SAIJ160X125-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. It provides a usable travel window of 75-125 mm, letting you dial back the 125 mm nominal stroke by up to 50 mm without adding external stops.
This SKU ships with a SUS304 stainless steel rod (option B) for superior corrosion resistance and a PT tapered port. It includes a magnet for CMSE reed and DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop to set the travel end, so it will not hold a load without live air pressure.

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 SAIJ160BX125-50S Is Used
Press Stroke Tuning
Dial in the exact 75-125 mm travel window during press setup, using the rear stopper to compensate for material thickness variations without changing the cylinder.
Product Changeover
Quickly adapt automated lines to new product sizes by adjusting the retract end-position up to 50 mm, minimizing downtime between production runs.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-50S the Right Cylinder?
Because the 50 mm adjustment window creates a 75-125 mm travel range, you can adapt machine stops on the fly instead of swapping out a fixed-stroke SAI cylinder.
For an exact ISO 15552 replacement, match the 160 mm bore, 125 mm stroke, 50 mm adjust code, PT port thread, and the -S magnet. Note that the rear adjuster is a travel stop, not a locking device. If your application requires true load-holding without live air, use an AirTAC SAIL or BSAI cylinder instead. Furthermore, while the 40 mm rod and M36x2 thread handle high stresses, any stroke near or over 300 mm demands an external guide rail to prevent side-load damage.
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 SAIJ160BX125-50S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the 125 mm nominal stroke back by up to 50 mm, creating a usable travel window of 75-125 mm. It sets the end position but does not lock the load without live air pressure.
