About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-75S
The AirTAC SAIJ80X160-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 160 mm travel to a specific end-position within an 85-160 mm usable window. The extruded aluminum barrel features sensor grooves on both sides, and because this unit includes the -S magnet option, it works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection.
This specific SKU is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance, paired with PT tapered port threads (G3/8). The rear adjuster acts purely as a mechanical stop to set the retract end-position during commissioning or product changeover; it does not lock or hold the load without continuous live air pressure. For load-holding requirements without live air, an external rod lock, a pilot-operated check valve, or related AirTAC series like SAIL or BSAI must be used instead.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80BX160-75S Is Used
Product Changeover
Dial in the exact retract position within the 85-160 mm window during packaging line format changes without replacing hardware.
End-Position Tuning
Fine-tune the mechanical stop at machine commissioning to perfect the stroke end-point without adding external spacers.
Variable Assembly Stops
Adjust the travel end on the fly for multi-model assembly lines requiring different retract distances from a single cylinder.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX160-75S the Right Cylinder?
Choose this 80 mm bore adjustable-stroke cylinder when your machine setup requires variable end-stops or frequent product-size changeovers, letting you fine-tune the 85-160 mm travel window without swapping out the entire cylinder or bolting on external stops. If your application requires less force, stepping down to a 63 mm bore drops the 0.5 MPa pull force to 1402 N, whereas stepping up to a 100 mm bore increases the 0.5 MPa push force to 3927 N. To replace this cylinder with an equivalent ISO 15552 unit, match the 80 mm bore, 160 mm stroke, 75 mm adjustment range, PT G3/8 port, SUS304 rod, and -S magnet configuration.
Because this model features a 25 mm rod diameter and an M20x1.5 rod thread, it handles side loads well, but any long unsupported stroke still necessitates an external guide to prevent rod binding. Note that SAIJ supports a reduced mounting set—Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting the FB, CA, CB, and CR mounting styles found on some other profile cylinders.

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 SAIJ80 Adjustable Cylinder SAIJ80BX160-75S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 75 mm from the 160 mm nominal stroke, providing an adjustable 85-160 mm window. It sets the end position but does not lock or hold the load without live air pressure.
At 0.7 MPa, the push force increases to 4523 N.
