Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X750-20S
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X750-20S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 750mm stroke, 3/8" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X750-20S
The AirTAC SAUJ80X750-20S is a double-acting single-rod profile cylinder with an on-site extend-stroke trim window. An external stop screw lets you shorten the 750 mm nominal stroke by up to 20 mm, yielding a usable 730-750 mm forward travel without buying a new actuator. The extruded aluminum profile barrel makes it shorter than an ISO 15552 unit of the same bore. It features a 3/8" port, an M20x1.5 rod thread, and 28 mm adjustable air cushions.
This 80 mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, peaking at 4523 N push at 0.9 MPa. A practical computed insight: the safe working load is roughly 1508 N (about 60% of the 0.5 MPa push figure), translating to a vertical lift capacity of approximately 128 kg with a 2:1 safety margin. The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG position sensing.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X750-20S Is Used
Press Depth Calibration
Ideal for light pressing tasks where the 20 mm stop screw fine-tunes the final 730-750 mm extend position to perfect component seating depth.
Extended Transfer Diverting
Handles long-reach diverting on wide conveyors, using the magnetic piston to confirm full extension and the adjustability to set exact reach.
Pallet Stop Positioning
Serves as an extended pallet stop where the exact contact point varies by pallet type, letting operators trim the 750 mm stroke on-site.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X750-20S the Right Cylinder?
When sizing this actuator, compare both ways: the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore offers 3927 N. Choose the 80 mm bore when your application demands the 2513 N thrust at 0.5 MPa. Select the SAUJ over a fixed-stroke SAU when you need final end-position tuning during machine commissioning or maintenance, avoiding the cost of external mechanical stops. The 20 mm adjust window is ideal for fine-tuning clamping or pressing depth. Mounting options include Basic, FA flange, and LB foot styles, sharing compatibility with the AirTAC SC series. Because the stroke is 750 mm, you must use external guides to prevent rod bending and manage side loads. The -S magnet enables electronic or reed switch sensing.

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 — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X750-20S FAQ
This 80 mm bore cylinder provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N at 0.9 MPa. The theoretical max force is 513 kgf at 1.0 MPa. The external stop screw allows you to shorten the 750 mm maximum extend stroke by up to 20 mm on-site, giving a usable range of 730-750 mm.
The -S suffix means a magnet is installed for CMSG, DMSG, or EMSG sensors. Regarding load holding: a plain cylinder does not hold its load on air loss or when the valve is centered, as the piston drifts and the 28 mm air cushion only decelerates near stroke end. The stop screw sets the end position but is not a load lock. For a held load, use an external rod lock or pilot-operated check valve.
