About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X130-20S
The AirTAC SAIJ160X130-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 110-130 mm usable travel window, letting you dial back the nominal 130 mm stroke by up to 20 mm during machine commissioning. Equipped with a -S magnet, it integrates seamlessly with AirTAC CMSE reed and DMSE solid-state sensors via the dual-side barrel grooves.
Delivering 10053 N of pull force at 0.5 MPa, this large-bore actuator handles heavy-duty tasks. The robust 40 mm carbon steel rod and M36x2 thread handle high side loads, while the extruded aluminum barrel maintains a standard ISO 15552 mounting interface. Note that the rear adjuster acts purely as a travel stop for end-position tuning, not as a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X130-20S Is Used
Press Fit Tuning
Dial in the exact 110-130 mm insertion depth for heavy-duty press fits without changing the cylinder or adding external stopper blocks.
Product Changeovers
Quickly adjust the retract end-position by up to 20 mm on automated lines handling varying large-component sizes.
Machine Commissioning
Fine-tune the final end-stop during initial setup to compensate for mechanical tolerances in heavy machinery.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X130-20S the Right Cylinder?
Choose this 160 mm bore cylinder when your application requires substantial force (10053 N pull at 0.5 MPa) but the exact end-of-stroke position needs fine-tuning on the fly. If your setup needs even more thrust, stepping up to the 200 mm bore yields 15080 N of pull force at 0.5 MPa. Conversely, dropping to the 125 mm bore reduces the pull force to 5734 N. Because the stroke is 130 mm, which is below the 300 mm threshold, an external guide is less critical, though the 40 mm rod still provides excellent rigidity.
The adjustable stroke is ideal for product changeovers where hitting a precise end-stop matters without swapping cylinders. If your machine requires the load to be held mechanically without live air pressure, a plain SAIJ is insufficient since the rear adjuster is only a stop. For those scenarios, consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead. To replace this unit, match the 160 mm bore, 130 mm stroke, 20 mm adjustment, PT tapered ports, and -S magnet.

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 SAIJ160X130-20S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from 130 mm down to as little as 110 mm. This creates a 110-130 mm adjustable travel window for fine-tuning the end position at commissioning, but it does not lock the load without live air pressure.
