About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-20S
The AirTAC SAIJ80X600-20-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 580 to 600 mm, allowing you to dial back the end-of-stroke position by up to 20 mm during commissioning without adding external stops. In the 80 mm bore class, it generates 2513 N of pull force at 0.5 MPa and up to 4523 N at 0.9 MPa.
This SKU is equipped with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered G3/8 ports ensure a tight pneumatic connection. It supports a speed range of 30-800 mm/s and uses adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-20S Is Used
Variable End-Stop Setup
Dial in the exact retract distance within the 580-600 mm window during machine commissioning to accommodate varying product lengths without swapping cylinders.
Long-Stroke Forming
Ideal for 80 mm bore pressing tasks where the 20 mm adjuster fine-tunes the final approach position, while the SUS304 rod handles harsh environments.
Product Changeover Lines
Quickly adjust the stroke end-point by up to 20 mm on automated conveyors when switching between different package sizes or tooling profiles.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-20S the Right Cylinder?
Choose this adjustable 80 mm bore cylinder when your application requires precise end-position tuning on a 600 mm stroke, delivering 2513 N pull force at 0.5 MPa. If you need less force, the 63 mm bore offers 1402 N pull at 0.5 MPa; for heavier loads, stepping up to the 100 mm bore provides 3681 N pull at 0.5 MPa. Because the 600 mm stroke is substantial, an external guide is strongly recommended to prevent excessive side-loading on the 25 mm rod.
The rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure. For drop-safe load holding, consider the SAIL or BSAI series instead. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) with no FB, CA, CB, or CR brackets.

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 SAIJ80BX600-20S FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull force. At 0.7 MPa the push force is 3518 N, and it reaches 4523 N push at 0.9 MPa.
The rear adjuster screw lets you shorten the 600 mm nominal stroke by up to 20 mm, creating a 580-600 mm usable travel window. It functions as a mechanical stop to fine-tune the end position and does not lock the load without air pressure.
