About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-75S
The AirTAC SAIJ160X180-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 180 mm travel to anywhere within a 105-180 mm usable window. It features a standard carbon steel piston rod and a PT tapered port. Delivering 10053 N of pull force at 0.5 MPa, it handles heavy-duty positioning with precision.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops during machine commissioning or product changeovers. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors. The rear adjuster functions strictly as a travel stop to set end-position deceleration, not as a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-75S Is Used
Variable End-Stop Positioning
Dial in the exact end-of-stroke position within the 105-180 mm window during machine setup, avoiding the need to physically swap out the entire cylinder for different product sizes.
Heavy-Duty Product Changeover
Rapidly adjust the stroke length on automated heavy-load conveyors or press lines when switching between product variants, using the rear screw to fine-tune the travel distance.
Large Fixture Calibration
Leverage the 10053 N pull force and the 75 mm adjustment range to precisely calibrate clamping or positioning fixtures on the factory floor without adding external mechanical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-75S the Right Cylinder?
Choose this 160 mm bore when you need to step up from a 125 mm cylinder (which provides 5734 N pull at 0.5 MPa) to handle heavier loads requiring up to 10053 N pull force at the same 0.5 MPa pressure. The 75 mm adjustment range is particularly useful for packaging lines or assembly fixtures where the end-stop position frequently changes between product variants, replacing the need for fixed-stroke SAI cylinders. For any load-holding requirements without live air pressure, this cylinder is not sufficient; you should consider the SAIL air-released lock, the BSAI clamp-lock, or an external pilot-operated check valve. When replacing an ISO 15552 cylinder, match the 160 mm bore, 180 mm stroke, PT port thread, and the -S magnet requirement.

- ✓ 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 SAIJ160X180-75S FAQ
The rear adjuster acts as an external mechanical stop that shortens the effective stroke. For this model, the nominal 180 mm stroke can be adjusted back by up to 75 mm, providing a usable travel window of 105-180 mm. The adjuster only sets the travel end and does not lock the load without live air.
At a 0.5 MPa operating pressure, this cylinder provides 10053 N of pull force and 14074 N of push force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 2050 kgf.
