About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-75S
The AirTAC SAIJ160X260-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 185 to 260 mm for precise end-position tuning during commissioning. The barrel is extruded aluminum with sensor grooves on both sides, and this -S variant includes a magnet for position detection.
This model features a SUS304 stainless steel rod for corrosion resistance and uses a PT tapered port thread. The rear adjuster acts purely as a mechanical stop to set the travel end and relies on the integrated air cushion for deceleration; it does not lock or hold the load without live air pressure. For load-holding requirements, a SAIL or BSAI variant would be 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 SAIJ160BX260-75S Is Used
Heavy Machinery Setup
Fine-tunes the 185-260 mm travel window during heavy equipment assembly, allowing precise positioning of large components without machining custom external stops.
Product Size Changeover
Adjusts the retract end-position on the fly when a production line switches to a different product size, utilizing the 75 mm adjustment range to adapt quickly.
Press End-Stop Tuning
Dials in the exact bottom-dead-center for a pressing operation, using the rear stopper to compensate for mechanical wear over time while leveraging the 40 mm rod for stability.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-75S the Right Cylinder?
The adjustable stroke is ideal for product changeovers on a line, allowing operators to trim the stroke by up to 75 mm rather than installing a fixed-stroke SAI cylinder of a different length. When replacing an ISO 15552 cylinder, match the 160 mm bore, 260 mm nominal stroke, PT G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2—omitting FB, CA, CB, CR). Because the stroke is 260 mm, ensure adequate external guiding to prevent side-loading on the 40 mm rod.
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 SAIJ160BX260-75S FAQ
The rear adjuster allows you to shorten the effective stroke by up to 75 mm from the 260 mm nominal length, creating a usable travel window of 185 to 260 mm. The adjuster functions as a mechanical stop and does not hold the load without live air pressure.
