Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X750-30S
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X750-30S 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 SAUJ80X750-30S
The AirTAC SAUJ80X750-30S is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the 750 mm nominal stroke down by up to 30 mm, yielding a usable 720-750 mm window without buying a new actuator. It features a 3/8" port, an M20x1.5 rod thread, and a 28 mm adjustable air cushion at each end. The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG position switches.
This 80 mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, peaking at 513 kgf at 1.0 MPa. A practical safe working load is roughly 1508 N (60% of the 0.5 MPa push), translating to a 128 kg vertical lift with a 2:1 safety margin. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore, and a Viton H seal option extends operating temperature to 150 C.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X750-30S Is Used
Variable Pitch Indexing
Dial in the exact push distance on a 750 mm cycle by turning the stop screw up to 30 mm, perfect for machines running mixed material lengths.
Pallet Stop Calibration
Tune the extend endpoint on-site to accommodate slightly different pallet dimensions without reprogramming the machine logic.
Diverter Gate Positioning
Adjust the extend stroke by up to 30 mm to alter the divert angle precisely for varying product widths on the line.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X750-30S the Right Cylinder?
Size this 80 mm bore against the 63 mm and 100 mm neighbors: the 63 mm yields 1559 N push while the 100 mm hits 3927 N at 0.5 MPa. This SAUJ80X750-30S provides 2513 N push at 0.5 MPa, making it ideal for medium-heavy loads. Choose the 30 mm adjust window when your final end-position needs field tuning; it beats welding an external stop on a fixed SAU. Basic, FA flange, and LB foot mounts are available, sharing mounting compatibility with the AirTAC SC series. Because the -S model includes a magnet, you can fit CMSG/DMSG/EMSG sensors directly. At 750 mm stroke, prevent rod bending by using an external guide to absorb side loads.

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 SAUJ80X750-30S FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull; at 0.7 MPa it pushes 3518 N, and 4523 N at 0.9 MPa. The theoretical max is 513 kgf at 1.0 MPa. The 750 mm nominal extend stroke can be shortened by up to 30 mm via the external stop screw, giving a 720-750 mm working range. It uses a 3/8" port and a 25 mm rod.
The -S suffix means a piston magnet is installed, allowing CMSG, DMSG, or EMSG electronic switches to track position. The stop screw sets the end position but is not a load lock; the air cushion only decelerates the piston. If air is lost, the cylinder drifts, so use an external rod lock or pilot-operated check valve for secure load holding.
