About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-40
The AirTAC SAIJ160X170-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The integrated rear stopper allows you to fine-tune the effective travel window down from 170mm to a precise 130mm limit during commissioning.
This specific SKU uses a PT tapered port thread and excludes a magnet, meaning it is not set up for position sensing without modification. Unlike fixed-stroke SAI units, this adjustable model lets you dial in the exact retract end-position on product changeovers without swapping the barrel or adding external stops. Remember that the rear adjuster functions strictly as a travel stop 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 SAIJ160BX170-40 Is Used
Heavy Press Tuning
Dial in the exact 130-170mm travel window during heavy press commissioning to accommodate varying material thicknesses without external stopper blocks.
Product Changeover
Quickly adjust the retract end-position on automated assembly lines when switching between different product sizes or operational parameters.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-40 the Right Cylinder?
If your setup needs less force, stepping down to a 100mm bore yields 5497N at the same pressure, whereas moving up to a 200mm bore offers 21991N. The 40mm adjustment range is ideal for machinery requiring variable end-stops across different product sizes.
Because this is a 170mm stroke, you must account for potential side loads by using an external guide to prevent rod wear. To replace this cylinder with an ISO 15552 equivalent, match the 160mm bore, 170mm stroke, 40mm adjustment, PT G3/4 port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting interface. For applications requiring the load to be held without continuous air pressure, this cylinder is insufficient; consider the SAIL pneumatic lock or BSAI clamp-lock series 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 SAIJ160BX170-40 FAQ
The maximum allowable operating pressure is 1.0 MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from the nominal 170mm down to 130mm. It is a travel stop for end-position tuning, not a lock, and cannot hold the load without live air pressure.
