Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X325-30
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X325-30 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 325mm 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 SAUJ80X325-30
The AirTAC SAUJ80X325-30 is a double-acting, single-rod profile cylinder with an on-site extend stroke adjustment window of 30 mm. You can trim the usable extend stroke from 325 mm down to 295 mm using the external stop screw. It features a 3/8" port, an M20x1.5 rod thread, and 28 mm adjustable air cushions at each end. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This 80 mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, peaking at a theoretical 513 kgf at 1.0 MPa. A practical computed insight: the safe working load is roughly 1508 N, and it can vertically lift about 128 kg with a 2:1 margin. Since this SKU lacks the -S magnet option, it cannot accept magnetic switches. If you need to hold a load vertically, note that the stop screw and cushions only set position and decelerate; they do not lock the rod on air loss, so add an external rod lock.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X325-30 Is Used
Adjustable Pressing Stations
Dial in the exact 295-325 mm extend depth on-site to accommodate varying material thicknesses without changing the cylinder.
Variable Length Diverters
Trim the extend stroke by up to 30 mm to fine-tune the pusher reach for different package sizes on a packaging line.
Custom Height Stops
Set precise mechanical end positions for palletizing tasks where the final stop height needs slight on-site adjustment.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X325-30 the Right Cylinder?
When sizing this model, compare it against the neighboring 63 mm bore, which provides 1559 N push at 0.5 MPa, and the 100 mm bore, which yields 3927 N. This 80 mm unit delivers 2513 N push at 0.5 MPa, striking a balance for medium-heavy duties. Choose the SAUJ over a fixed SAU when your machine build requires field-tuning the extend endpoint without buying a new cylinder. The 30 mm adjust window is ideal for dialing in exact pressing or clamping depth. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. Because the stroke is 325 mm, always use external guides to prevent rod bending under side loads. This non-magnet SKU cannot take 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 SAUJ80X325-30 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull; at 0.7 MPa it yields 3518 N push, and 4523 N at 0.9 MPa. The theoretical max is 513 kgf at 1.0 MPa. The 325 mm nominal extend stroke can be shortened by up to 30 mm on-site via the external stop screw, giving a usable range of 295-325 mm. It uses a 3/8" port.
The external stop screw mechanically limits the piston's extend travel, letting you set the exact end position. This stop and the 28 mm air cushions only decelerate the piston; they do not lock the rod. If air pressure drops, the cylinder will drift. For load holding, install an external rod lock or pilot-operated check valve.
