About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-20S
The AirTAC SAIJ160X120-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 100 to 120 mm from its 120 mm nominal stroke. Built with a robust 40 mm carbon steel rod and a PT tapered G3/4 port, it delivers a pull force of 9425 N at 0.5 MPa and up to 18095 N at 0.9 MPa. The integrated -S magnet enables position detection with AirTAC CMSE reed or DMSE electronic sensors along the dual-sided barrel grooves.
This adjustable-stroke design allows you to fine-tune end positions at commissioning without swapping the cylinder or adding external stops. The rear adjuster acts as a travel stop to set the retract position, not as a load-holding lock. For applications requiring position maintenance without live air pressure, consider the SAIL pneumatic lock or BSAI clamp-lock variants.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-20S Is Used
Heavy Press Fitting
Dial in the exact 100-120 mm end position for precision bearing seating or heavy press operations without machining external stopper blocks.
Machine Changeover
Quickly adapt the retract stroke during product family transitions on large assembly lines, using the rear screw to accommodate varying part heights.
Large Mold Handling
Fine-tune the retraction end-stop for heavy mold or tooling positioning, relying on the 18095 N push force at 0.9 MPa to move substantial loads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-20S the Right Cylinder?
Choose this 160 mm bore when your application requires significantly more thrust than the 100 mm bore (3681 N pull at 0.5 MPa) but less than the massive 200 mm bore (15080 N pull). The 20 mm adjustment range is ideal for machine setups requiring variable end-stops during product changeover. Since the 120 mm stroke is under 300 mm, side-load risks are moderate, but the substantial 40 mm rod thread helps handle higher bending loads. As an ISO 15552 interchangeable cylinder, ensure your replacement matches the 160 mm bore, 120 mm stroke, PT G3/4 port, and -S magnet configuration. Mounting options include 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 SAIJ160X120-20S FAQ
At 0.5 MPa, it provides 10053 N push and 9425 N pull force. At 0.9 MPa, the push force reaches 18095 N, with a maximum push force of 2050 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 120 mm nominal stroke by up to 20 mm, providing an effective travel window of 100 to 120 mm. It sets the end position but does not lock the load without live air pressure.
