About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-50S
The AirTAC SAIJ160X175-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a robust 14074N push force at 0.7 MPa and utilizes a carbon steel piston rod with an M36x2 thread. The integrated magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches.
This specific SKU allows you to dial back the 175mm nominal stroke by up to 50mm, yielding a usable travel window of 125-175mm. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered port threads ensure a tight, reliable pneumatic connection.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-50S Is Used
Machine Changeover
Quickly fine-tune the 125-175mm travel window during product size transitions on a packaging line without physically replacing the actuator.
End-Stop Calibration
Dial in the exact retraction point during machine commissioning to prevent mechanical crashes, using the rear stopper instead of external spacers.
Heavy Assembly Press
Leverage the 14074N push force to seat heavy components, adjusting the final 50mm of stroke to accommodate varying part tolerances.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X175-50S the Right Cylinder?
Choose this adjustable model when you need precise end-position tuning during commissioning or product changeover without swapping the cylinder or adding external stops. If your application requires less force, stepping down to a 100mm bore yields 5497N push at 0.7 MPa; stepping up to a 200mm bore provides 21991N. To match this ISO 15552 replacement exactly, verify the 175mm stroke, 50mm adjustment, G3/4 PT port, and the -S magnet requirement.
Because the 175mm stroke is relatively long, ensure adequate external guidance to prevent excessive side loads on the M36x2 rod. The rear adjuster acts strictly as a travel stop and cannot hold a load without live air pressure; for true load-holding without continuous air, consider an external rod lock or the related SAIL or BSAI models.
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 SAIJ160X175-50S FAQ
At a 0.7 MPa operating pressure, this 160mm bore cylinder generates a push force of 14074N and a pull force of 9425N. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster screw allows you to shorten the effective stroke from its 175mm nominal length down to a minimum of 125mm. This provides a 50mm tuning window for precise end-positioning without changing the cylinder.
