Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X65-30S
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X65-30S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 65mm 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 SAUJ80X65-30S
The AirTAC SAUJ80X65-30S is a double-acting single-rod profile cylinder built for on-site stroke adjustment. An external stop screw lets you trim the extend stroke by up to 30 mm, giving a usable working stroke of 35 to 65 mm. The 80 mm bore uses a 3/8" port and a 25 mm rod with an M20x1.5 thread. Its extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore.
This bore delivers 2513 N push and 2268 N pull at 0.5 MPa, peaking at 4523 N push at 0.9 MPa. For sizing, the safe working load is roughly 1508 N (about 60% of the 0.5 MPa push), and it can vertically lift around 128 kg with a 2:1 margin. The -S suffix means a piston magnet is installed for CMSG, DMSG, or EMSG switches. Operating pressure spans 0.15 to 1.0 MPa, and a Viton H seal option raises the standard -20 to +70 C range up to 150 C.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X65-30S Is Used
Variable Depth Forming Press
Dial in the exact 35 to 65 mm extend position for different material thicknesses using the stop screw without reprogramming the motion controller.
Adjustable Carton Sealing Head
Fine-tune the 80 mm bore stroke on the packaging line to accommodate varying box heights, ensuring consistent sealing pressure.
Tiered Pallet Stopper
Modify the extend stroke on-site to act as a physical stop for different pallet depths, relying on the 2513 N push force to halt incoming loads.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X65-30S the Right Cylinder?
Choose this 80 mm bore if you need 2513 N push at 0.5 MPa, stepping down to the 63 mm bore (1559 N) for lighter loads or up to the 100 mm bore (3927 N) for heavier ones. The SAUJ80X65-30S is ideal when a fixed SAU plus an external mechanical stop is too bulky or hard to tune. Here, the stop screw provides a 30 mm adjustment window directly on the body. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. The -S magnet enables electronic position feedback. For strokes over 300 mm, always use external guide rails to prevent side-load wear, though this 65 mm unit is compact. Note that the stop screw sets end position but does not lock the load; use a pilot-operated check valve for holding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/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 — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X65-30S FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. Push rises to 3518 N at 0.7 MPa and 4523 N at 0.9 MPa. The 65 mm nominal extend stroke can be shortened by up to 30 mm via the external stop screw, yielding a 35 to 65 mm working range. The cylinder uses a 3/8" port and operates at 30-800 mm/s.
The -S suffix indicates a built-in piston magnet for mounting CMSG, DMSG, or EMSG sensors for position detection. Regarding load holding, the stop screw only sets the end position and the air cushions only decelerate; neither locks the load. If air pressure drops, the piston will drift. Use an external rod lock or pilot-operated check valve to hold a load securely.
