About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-75
The AirTAC SAIJ160X270-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 195 to 270 mm, allowing you to dial back the nominal stroke by up to 75 mm during commissioning.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjuster acts strictly as a mechanical stop for end-position tuning, not a lock for holding loads 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 SAIJ160BX270-75 Is Used
Machine Changeover
Dial in the 195-270 mm travel window instantly during product size transitions without changing the cylinder or adding external mechanical stops.
Corrosive Environments
Rely on the SUS304 stainless steel rod for reliable actuation in washdown or corrosive manufacturing settings.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-75 the Right Cylinder?
Choose this 160 mm bore when you need substantial thrust, such as stepping up from a 125 mm bore that yields 8590 N at 0.7 MPa. The 75 mm adjustment range is ideal for production lines requiring frequent product-size changeovers, letting you fine-tune the retract end-position without swapping cylinders or adding external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is solely a travel stop.
To replace an ISO 15552 cylinder, match the 160 mm bore, 270 mm stroke, 75 mm adjustment, PT G3/4 port, and your required mounting from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since the 270 mm stroke approaches the mid-range for this bore, ensure external guides are used if side loads are present, and note that this non-magnet variant does not support position sensing.
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 SAIJ160BX270-75 FAQ
The rear adjuster screw lets you mechanically shorten the effective stroke by up to 75 mm. This creates a usable travel window of 195 to 270 mm, allowing precise end-position tuning at commissioning without replacing the cylinder.
