About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-50
The AirTAC SAIJ200X170-50 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering a substantial 15708 N push force at 0.5 MPa. It features an extruded aluminum barrel with sensor grooves on both sides and a robust 40 mm piston rod made from SUS420J2 stainless steel (code A). The integrated rear adjusting screw allows you to dial back the nominal 170 mm stroke by up to 50 mm, creating a precise 120-170 mm usable travel window for on-the-fly positioning.
This fine-tuning capability is ideal for product changeovers, letting you set exact end positions at commissioning without swapping hardware or adding external stops. The rear adjuster acts purely as a travel stop to set the deceleration point alongside the variable air cushions, not as a lock to hold the load without live air. Fluid is filtered air, operating pressure ranges from 0.15 to 1.0 MPa, and the PT tapered port threads ensure a secure high-flow connection.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-50 Is Used
Heavy Press Tuning
Dial in the exact 120-170 mm travel window during heavy press commissioning to accommodate different material thicknesses without external stopper hardware.
Product Changeover Stops
Adjust the rear stopper on the fly for varying package sizes on a high-thrust conveyor diverter, ensuring precise end-positioning without replacing the cylinder.
Variable End-Position Diverter
Utilize the 50 mm adjustment range to fine-tune the deceleration point and end-stop for heavy pallet routing, relying on the 40 mm SUS420J2 rod for durability.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-50 the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your process demands extreme thrust, such as 15708 N push or 15080 N pull at 0.5 MPa, alongside variable end-stop requirements. If your application needs less force, stepping down to a 160 mm bore yields 10053 N push at 0.5 MPa, which might better suit medium-heavy loads while saving physical space. Choose the SAIJ adjustable design over a fixed SAI when you anticipate product-size changes or need to trim the travel window during machine setup.
For load-holding without continuous live air pressure, note that this cylinder's rear stopper and air cushions cannot maintain position; you would need an external rod lock, a pilot-operated check valve, or a related AirTAC type like SAIL or BSAI. To match this exact ISO 15552 interchangeable replacement, specify: 200 mm bore, 170 mm stroke, 50 mm adjustment, PT port threads, SUS420J2 rod material, and no sensor magnet. Because the stroke is 170 mm, standard external guiding is recommended to manage side loads.

- ✓ 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 SAIJ200 Adjustable Cylinder SAIJ200AX170-50 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjusting screw acts as a mechanical stop that lets you trim the effective travel from the 170 mm nominal stroke down to as little as 120 mm. It sets the end position and deceleration point but does not lock the load without live air pressure.
