About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX175-50S
The AirTAC SAIJ160X175-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -50 mm adjustment mechanism allows you to fine-tune the effective travel window down to 125 mm from the 175 mm nominal stroke without swapping out the unit.
This specific SKU is built with a SUS304 stainless steel rod (code B) for superior corrosion resistance and features a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet option enables precise end-of-travel detection using AirTAC CMSE reed or DMSE electronic sensors. The rear stopper screw sets the retract end position, but it functions only as a travel limiter and does not hold the 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 SAIJ160BX175-50S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 125-175 mm window during commissioning to perfectly align heavy press tools without adding external mechanical stops.
Product Size Changeover
Quickly adapt automated machinery to new product lengths by adjusting the stroke up to 50 mm, significantly reducing setup downtime between production runs.
Corrosive Environment Testing
Leverage the SUS304 stainless steel rod for reliable actuation in washdown or chemical testing areas where standard carbon steel rods would fail.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX175-50S the Right Cylinder?
The 50 mm adjustable range is ideal for machine setups requiring variable end-stops during product changeovers, eliminating the need to physically swap a fixed-stroke SAI cylinder. For exact ISO 15552 replacement matching, specify the 160 mm bore, 175 mm stroke, 50 mm adjustment, PT port thread, SUS304 rod, and -S magnet.
Because the nominal stroke of 175 mm is below the 300 mm threshold, external side-load guides are less critical than with longer strokes, though the robust 40 mm rod and M36x2 thread handle substantial side loads directly. Remember that the rear adjuster and air cushions only decelerate the travel end; they do not act as a brake. If you need true load-holding without live air pressure, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
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 SAIJ160BX175-50S FAQ
The rear adjuster screw allows you to shorten the 175 mm nominal stroke by up to 50 mm, creating a usable travel window of 125 to 175 mm. This stopper only limits the travel end and does not lock the load without continuous air pressure.
