About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-75S
The AirTAC SAIJ160X140-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 65 to 140 mm, allowing you to dial back the nominal stroke by up to 75 mm during machine setup or product changeover. In the 160 mm bore class, it generates 14074 N of push force and 9425 N of pull force at 0.7 MPa.
This unit includes a magnetic piston for position sensing with AirTAC CMSE reed and DMSE electronic switches. The carbon steel rod is paired with a PT tapered G3/4 port, while the extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a mechanical stop to set the end position and cannot hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-75S Is Used
Product Changeover Tuning
Quickly reconfigure the 65 to 140 mm travel window on packaging lines handling varying container sizes without physically replacing the actuator.
Heavy Press Positioning
Leverage the 14074 N push force at 0.7 MPa to execute precise pressing operations while using the rear screw to dial in the exact final depth.
Machine Commissioning Setup
Fine-tune the end-of-stroke position during initial equipment buildup to perfect timing sequences and avoid mechanical hard crashes.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-75S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires heavy thrust but variable end-stop positioning. If your process demands less force, stepping down to a 125 mm bore yields 8590 N of push at 0.7 MPa. Conversely, moving up to a 200 mm bore provides 21991 N. Choose this adjustable-stroke SAIJ model over a fixed-stroke SAI when you need fine end-position tuning at commissioning without swapping the cylinder or adding external stops.
For load-holding applications without continuous air pressure, note that the rear adjuster is a travel stop, not a lock; you would need an external rod lock, a pilot-operated check valve, or an AirTAC SAIL or BSAI cylinder. When replacing an ISO 15552 cylinder, match the 160 mm bore, 140 mm stroke, 75 mm adjustment range, PT G3/4 port, and the -S magnet requirement. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ160X140-75S FAQ
The rear adjuster screw lets you mechanically shorten the effective travel from the nominal 140 mm down to 65 mm, providing a 75 mm adjustment window. It acts as a physical stop to set the retract end position precisely during commissioning or changeover.
At 0.7 MPa, it provides 14074 N of push force and 9425 N of pull force. The operational speed range for this 160 mm bore is 30 to 500 mm/s.
