About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-50S
The AirTAC SAIJ160X65-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits precise end-position tuning. With a nominal 65 mm stroke and a 50 mm adjustment range, the usable travel window can be dialed back anywhere from 15 to 65 mm. This heavy-duty 160 mm bore delivers 14074 N of push force at 0.7 MPa, making it suitable for high-thrust operations.
This specific configuration includes a SUS420J2 stainless steel rod (option A) for improved corrosion resistance in humid environments. The -S magnet option enables position sensing via AirTAC CMSE reed switches or DMSE electronic solid-state sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the rear stopper acts purely as a travel stop, not a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-50S Is Used
Press Stroke Tuning
Dial in the exact end-position for a high-force press during setup, adjusting the 65 mm stroke down to 15 mm to accommodate varying material thicknesses without changing the tooling.
Product Changeover
Quickly reconfigure the retract distance on an automated assembly line when switching to a new product size, using the 50 mm adjustment range to skip external mechanical stops.
Heavy Assembly Clamping
Leverage the 18095 N push force at 0.9 MPa to secure large components during heavy-duty assembly, relying on the stainless steel rod for durability in industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX65-50S the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires substantial force, as it yields 10053 N push at 0.5 MPa. If your setup demands less thrust, stepping down to the 125 mm bore provides 6136 N at 0.5 MPa. The 50 mm adjustable stroke is highly beneficial during machine commissioning or product changeovers, allowing you to fine-tune the retract end-stop without swapping cylinders or adding external shims. For load-holding without live air pressure, this cylinder is insufficient; consider the AirTAC SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match these exact parameters: 160 mm bore, 65 mm stroke, 50 mm adjustment, PT tapered port (G3/4), and the -S magnet. The SAIJ mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 configurations, omitting the FB, CA, CB, and CR mounts. The 40 mm rod and M36x2 thread provide high rigidity, but even with this robust design, long unsupported strokes still require an external guide to prevent side-loading damage.

- ✓ 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 SAIJ160AX65-50S FAQ
The rear of the cylinder features an external adjusting screw that acts as a mechanical stopper. For this model, it allows you to shorten the effective stroke by up to 50 mm, providing a usable travel window of 15 to 65 mm. It only sets the travel end and does not lock the load without live air pressure.
At a 0.5 MPa operating pressure, this cylinder provides 10053 N of push force and 9425 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 2050 kgf.
