Airtac SAIJ160 Adjustable Cylinder SAIJ160X1000-20S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X1000-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 1000mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X1000-20S
The AirTAC SAIJ160X1000-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 980 to 1000 mm. Delivering 18095 N of push force at 0.9 MPa, this carbon-rod actuator handles heavy-duty positioning. The integrated -S magnet supports position sensing via CMSE reed or DMSE electronic switches fitted into the dual-side barrel grooves.
Because the nominal 1000 mm stroke falls within the 1500 mm standard limit, it is a catalog configuration rather than a special order. The rear mechanical stopper allows precise end-position tuning during commissioning without adding external stops or swapping the cylinder. Note that this adjuster sets the travel limit and does not hold the load without live air; for true load-holding, consider an external rod lock or the AirTAC BSAI clamp-lock series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X1000-20S Is Used
Long-Stroke Press Setup
Dial in the exact 980 to 1000 mm travel limit during machine commissioning without installing bulky external stopper blocks on the frame.
Heavy Product Changeover
Quickly adapt the end-of-stroke position for varying large product sizes on an assembly line using the rear adjustment screw.
High-Force Positioning
Leverage 18095 N of thrust to move heavy pallets or fixtures while fine-tuning the final resting position by up to 20 mm.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X1000-20S the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore class (7068 N push at 0.9 MPa) lacks the necessary thrust, but step down if 11045 N from the 125 mm bore is sufficient. The 20 mm adjustment range is ideal for dialing in exact end positions during product changeover on long-stroke machinery. For a fixed stop without the tuning screw, the standard SAI series is the alternative. This model includes a PT tapered port, carbon steel rod, and a -S magnet. Given the 1000 mm stroke, the unsupported length demands an external guide to prevent excessive side-loading on the 40 mm rod and M36x2 thread.
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 SAIJ160 Adjustable Cylinder SAIJ160X1000-20S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates 18095 N of push force and 9425 N of pull force. The maximum allowable pressure is 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 1000 mm down to 980 mm. It is a travel limit, not a lock, so live air is still required to hold the load.
