About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-100S
The AirTAC SAIJ80X160-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 2513N of push force at 0.5 MPa and features a PT tapered port thread alongside a carbon steel rod. By integrating a -S magnet, this unit directly supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the dual-side extruded aluminum barrel grooves.
This specific SKU provides a nominal 160mm stroke that can be dialed back by up to 100mm, creating a highly versatile 60-160mm usable travel window. The rear screw stopper allows precise end-position tuning during commissioning without adding external stops. It utilizes a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR configurations.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-100S Is Used
Variable End-Stop Tuning
Dial in the exact 60-160mm end position during machine commissioning to accommodate varying material thicknesses without machining new hard stops.
Product Size Changeover
Rapidly reconfigure packaging lines for different carton sizes by adjusting the rear screw up to 100mm, drastically reducing mechanical setup time.
High-Force Positioning
Leverage the 2513N push force at 0.5 MPa to move heavy pallets or fixtures, relying on the 25mm rod to handle significant side loads during transit.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-100S the Right Cylinder?
Choose this 80mm bore cylinder when an application demands high thrust (2513N push at 0.5 MPa) alongside extreme stroke flexibility; if you need less force, stepping down to a 63mm bore yields 1559N. The massive 100mm adjustment window is perfect for machines processing multiple product sizes, allowing rapid changeover simply by turning the rear screw rather than physically swapping cylinders. For fixed-position tasks without variation, a standard SAI model is simpler.
When replacing an ISO 15552 cylinder, match the 80mm bore, 160mm nominal stroke, PT port thread, and the -S magnet requirement. Remember that the rear adjuster functions strictly as a travel stop, not a lock; it cannot hold a load without live air. For dead-load holding, select an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or install an external pilot-operated check valve.
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 SAIJ80 Adjustable Cylinder SAIJ80X160-100S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At a maximum 1.0 MPa pressure, it achieves a top push force of 4523N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke from its 160mm nominal length down to as little as 60mm. This creates a 60-160mm travel window for fine-tuning end positions without replacing the cylinder.
