About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX120-50S
The AirTAC SAIJ160X120-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from a 120 mm nominal stroke to a 70 mm minimum. This creates a highly versatile 70-120 mm usable window, letting you dial in the exact end position during commissioning or product changeover without swapping the cylinder or adding external stops.
This specific SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and ships with a magnet for position sensing. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE solid-state switches. The G3/4 port and 50 mm cushion strokes manage energy absorption, but note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure. Mounting options utilize the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ160BX120-50S Is Used
Machine Format Changeover
Leverage the 70-120 mm travel window to quickly adapt end positions for different product sizes on a packaging line without replacing the cylinder.
Commissioning Fine-Tuning
Use the 50 mm rear adjuster to dial in the exact retract position during setup, eliminating the need to machine custom external stopper blocks.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX120-50S the Right Cylinder?
If you need less force, a 100 mm bore offers 5497 N. The 50 mm adjustment range is ideal for machinery requiring variable end-stops during format changes, replacing fixed-stroke SAI cylinders when external stops are impractical. Because the stroke is 120 mm, side-load risks are minimal, but an external guide is still recommended for heavy loads.
For load-holding without live air pressure, this cylinder's adjuster and air cushions act only as stops, not locks. You must integrate an external rod lock, a pilot-operated check valve, or switch to an AirTAC SAIL or BSAI cylinder. This SAIJ160X120-50-S is dimensionally interchangeable per ISO 15552 and is configured with PT tapered ports, a SUS304 rod, and a magnet for CMSE/DMSE sensors.

- ✓ 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 SAIJ160BX120-50S FAQ
The rear adjuster allows you to mechanically shorten the stroke from the 120 mm nominal length down to a 70 mm minimum, providing a 70-120 mm usable travel window. The adjuster acts as a stop to set the end position and does not lock or hold the load without continuous air pressure.
