About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX175-20
The AirTAC SAIJ160X175-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 175 mm travel by up to 20 mm for a precise 155-175 mm usable window. This makes it highly effective for robust positioning tasks that demand exact end-stop tuning.
Because it is an extruded aluminum profile cylinder rather than a tie-rod design, it integrates sensor grooves on both sides for straightforward switch mounting. The rear adjuster functions strictly as a mechanical stop to set the travel limit and relies on the integrated air cushion for end-of-stroke deceleration. It is not a locking mechanism, meaning the cylinder cannot hold a load safely 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 SAIJ160BX175-20 Is Used
Heavy Press Tuning
Dial in the exact 155-175 mm end position during heavy press commissioning to accommodate material thickness variations without changing the cylinder.
Product Changeover
Quickly adjust the rear stopper on a packaging line to handle different product sizes, utilizing the 20 mm trim range for rapid format transitions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX175-20 the Right Cylinder?
The adjustable stroke is ideal for machine commissioning or product changeovers, allowing operators to fine-tune the 155-175 mm travel window without physically swapping the cylinder or adding bulky external stops. For load-holding requirements without continuous air pressure, a plain SAIJ is insufficient and you should instead evaluate the SAIL or BSAI locking cylinder series.
To achieve a direct ISO 15552 replacement match, confirm the 160 mm bore, 175 mm stroke, 20 mm adjustment range, PT tapered port thread, and the SUS304 rod material. Since the stroke here is under 300 mm, side-load stress is manageable, but always ensure the M36x2 rod thread and 40 mm cushion are properly configured to handle the kinetic energy of this high-force unit.
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 SAIJ160BX175-20 FAQ
The rear adjuster acts as a mechanical stop that allows you to shorten the 175 mm nominal stroke by up to 20 mm, creating a usable travel window of 155 to 175 mm. This enables fine-tuning of the end position at commissioning without needing external stops.
