Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-20
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-20 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 1000mm 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 SAUJ80X1000-20
The AirTAC SAUJ80X1000-20 is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the working stroke by up to 20 mm, giving a usable range of 980-1000 mm. The extruded aluminum profile barrel is purposefully shorter than an ISO 15552 cylinder of the same bore. This 80 mm bore uses a 3/8" port and a 25 mm rod.
Force output is substantial: 2513 N push and 2268 N pull at 0.5 MPa, scaling to 4523 N at 0.9 MPa. For design sizing, the safe working load is roughly 1508 N (about 60% of the 0.5 MPa push figure), and it can vertically lift around 128 kg with a 2:1 safety margin. The 28 mm adjustable air cushions decelerate the payload smoothly at stroke end.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-20 Is Used
Long-Reach Press Tooling
Needs field stroke tuning to set the exact 980-1000 mm extend position for a large press without re-machining the stop block.
Pallet Transfer Pusher
Requires adjusting the extend end point by up to 20 mm on-site to accommodate varying pallet widths on the line.
High-Bay Diverter Arm
Demands a 2513 N push at 0.5 MPa to route heavy totes, with the stop screw allowing precise end-position calibration.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-20 the Right Cylinder?
Size this 80 mm bore against its neighbors: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. Choose the 80 mm when you need 2513 N push. Pick this SAUJ model over a fixed SAU when your machine assembly requires minor 0-20 mm extend length tweaking without buying new hardware. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. Because this is a 1000 mm stroke, you must use external guides to prevent rod bending and manage side loads. Note this SKU lacks a magnet (-S), so it cannot accept CMSG/DMSG/EMSG 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 SAUJ80X1000-20 FAQ
It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N at 0.7 MPa, and 4523 N at 0.9 MPa. The theoretical max is 513 kgf at 1.0 MPa. The 1000 mm extend stroke is the maximum; the external stop screw lets you shorten it by up to 20 mm on-site, yielding a 980-1000 mm usable window. It uses a 3/8" port and 28 mm adjustable cushions.
No. A plain SAUJ does not hold load on air loss; the piston drifts and the cushion only decelerates. For a held load, use an external rod lock or pilot-operated check valve. The stop screw sets the end position but is not a load lock. Also, this SKU lacks a magnet (-S), so it cannot take magnetic sensors.
