About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-20
The AirTAC SAIJ160X170-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. With a nominal 170 mm stroke and a 20 mm adjustment range, it provides a usable travel window of 150-170 mm to dial in exact stopping points during commissioning without adding external stops. It delivers robust thrust, pushing 14074 N at 0.7 MPa, making it well-suited for heavy-duty positioning tasks.
This unit is configured with a SUS304 stainless steel rod for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides for direct mounting of switches. The rear adjuster functions strictly as a travel stop to set deceleration and end-position, not as a lock to 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 SAIJ160BX170-20 Is Used
Machine Changeover
Quickly reconfigure the 150-170 mm end-stop for different product sizes on a single line without physically swapping the cylinder.
End-Position Tuning
Dial in the exact retract position during setup to compensate for mechanical wear or sensor drift without adding bulky external stoppers.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-20 the Right Cylinder?
Select this 160 mm bore cylinder when an application requires high force combined with precise end-stop tunability over a 150-170 mm window. Because this is a 170 mm stroke, side-load is moderate, but for any comparable setup exceeding 300 mm, an external guide is recommended to protect the 40 mm rod and M36x2 thread from deflection.
Choose the adjustable SAIJ over a fixed-stroke SAI when a machine requires product changeovers or variable end-stops on the same line. The mounting footprint is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts. Remember that the rear adjuster is a stop, not a brake; for true load-holding without live air, utilize an external rod lock or pilot-operated check valve, or select the SAIL or BSAI series.
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 SAIJ160BX170-20 FAQ
The rear adjuster screw acts as a mechanical stop that lets you trim the effective travel back by up to 20 mm from the nominal 170 mm stroke, creating a 150-170 mm usable window. It sets the travel end and deceleration point but does not lock or hold the load without continuous air pressure.
