Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X270-75
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X270-75 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 270mm 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 SAUJ80X270-75
The AirTAC SAUJ80X270-75 is a double-acting single-rod profile cylinder featuring a 270mm maximum extend stroke. An external stop screw lets you trim the extend stroke on-site by up to 75mm, yielding a usable working range of 195-270mm. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 3/8 inch port and M20x1.5 rod thread.
This 80mm bore generates 2513N push and 2268N pull at 0.5MPa, peaking at 513kgf at 1.0MPa. The safe working load is roughly 1508N (60% of the 0.5MPa push), translating to a 128kg vertical lift with a 2:1 margin. Adjustable 28mm air cushions decelerate the piston near the ends. Note this SKU lacks a magnet, so it cannot take a sensor.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X270-75 Is Used
Press Fit Tuning
Dialing in precise insertion depths on an assembly line where material thickness varies slightly, using the 75mm stop screw to set the exact 195-270mm extend position.
Variable Format Sealing
Adjusting the extend stroke on a packaging sealer to accommodate different carton heights without swapping out the entire pneumatic cylinder.
End-of-Stroke Damping
Setting a specific mechanical end position for a heavy load transfer station, relying on the 28mm adjustable cushion to decelerate the 80mm bore safely.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X270-75 the Right Cylinder?
When sizing, the neighboring 63mm bore offers 1559N push at 0.5MPa, while the 100mm bore provides 3928N. Choose this 80mm unit when your machine needs 2513N thrust at 0.5MPa plus field adjustability. Pick the SAUJ over a fixed SAU plus external stop when you need integrated stroke tuning without adding fabricated brackets. The 75mm adjust window is ideal for dialing in exact end positions during commissioning. Mounting options include Basic, FA flange, and LB foot, compatible with the AirTAC SC series. For the 270mm stroke, ensure external guide rails to prevent side-load wear. Since this is a no-S SKU, it cannot accept CMSG or DMSG sensors.
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 SAUJ80X270-75 FAQ
At 0.5MPa it provides 2513N push and 2268N pull. Push force is 3518N at 0.7MPa and 4523N at 0.9MPa, with a theoretical max of 513kgf at 1.0MPa. The nominal 270mm extend stroke can be shortened by up to 75mm via the external stop screw, giving a 195-270mm working range. The 3/8 inch port and 28mm cushions are fixed by the 80mm bore.
No. The stop screw only sets the end position, and the air cushion only decelerates the piston; neither acts as a load lock. If air is lost or the valve is centered, the piston will drift. For holding a load, you must use an external rod lock or a pilot-operated check valve. Also, this specific SKU lacks a magnet and cannot accept sensors.
