About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-20S
The AirTAC SAIJ80X160-20-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 20mm adjustment range, creating a precise 140-160mm usable travel window. This built-in adjustability allows you to dial in the retract end position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for position detection.
This model utilizes a 25mm carbon steel piston rod with an M20x1.5 thread, paired with PT tapered port threads and a G3/8 air supply. It supports speeds of 30-800mm/s and relies on adjustable air cushions at both ends to decelerate the load. The rear adjuster acts purely as a travel stop for position tuning, not as a locking device, meaning live air pressure is required to hold the load in place.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-20S Is Used
Product Changeover
Quickly adapt the end-stop from 140 to 160mm on packaging lines when switching to different container sizes, minimizing downtime.
End-Position Tuning
Fine-tune the retract stroke during machine commissioning to achieve exact clamping or pressing depths without external shims.
Automated Assembly
Handle heavier workpieces with 2513N push force at 0.5 MPa while retaining the flexibility to adjust the stroke window on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-20S the Right Cylinder?
Select this 80mm bore when an application requires higher thrust than a 63mm cylinder (which provides 1559N at 0.5 MPa) but still needs the flexibility of a variable end-stop. The 20mm adjustment window is perfect for machine setups requiring product changeovers, letting you fine-tune the 140-160mm travel without swapping out the entire cylinder. For fixed-length requirements without the need for end-tuning, a standard SAI cylinder is sufficient. Because the stroke is 160mm, side-load stress is moderate, but always ensure external guiding for heavy loads. To replace an ISO 15552 cylinder, match the 80mm bore, 160mm stroke, PT port thread, G3/8 port size, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
If your system needs to hold a load statically without continuous air pressure, the SAIJ adjuster and air cushions will not act as a brake. In those cases, consider an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder, or integrate an external pilot-operated check valve.

- ✓ 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 SAIJ80X160-20S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 20mm. This creates a usable travel window of 140-160mm, which can be fine-tuned during setup without replacing the cylinder.
