Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-75
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-75 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 100mm 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 SAUJ80X100-75
The AirTAC SAUJ80X100-75 is a double-acting single-rod profile cylinder with an on-site extend stroke adjustment window of 75 mm. You can trim the 100 mm maximum stroke down to a 25 mm effective extend length using the external stop screw. It features a hard-anodized extruded aluminum barrel, making it shorter than an ISO 15552 cylinder of the same 80 mm bore. The 3/8" port and M20x1.5 rod thread handle robust pneumatics.
This bore delivers 2513 N push and 2268 N pull at 0.5 MPa, peaking at a 4523 N push at 0.9 MPa. For sizing, the safe working load is roughly 1508 N, and it can manage a 128 kg vertical lift with a 2:1 margin. If your machine needs field stroke tuning without buying a new actuator, this beats a fixed SAU plus external stop. Note this non-magnetized SKU cannot take sensors, and the stop screw sets end position but does not lock loads.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-75 Is Used
Variable Pitch Indexing
Dial in exact 25 to 100 mm part ejection lengths on the fly without swapping actuators.
Adjustable Diverter Arm
Tune the extend stop up to 75 mm shorter to handle changing package widths on the line.
Variable Depth Pallet Stop
Shift the end position on-site to adapt to different pallet footprints quickly.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-75 the Right Cylinder?
When sizing this actuator, look both ways: the 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore hits 3927 N. This 80 mm bore gives 2513 N at 0.5 MPa. Choose the SAUJ over a fixed SAU when your assembly needs plus or minus 75 mm of extend flexibility during commissioning. The 3/8" ported body supports Basic, FA flange, and LB foot mounts, compatible with AirTAC SC series brackets. Because this specific SKU lacks the -S magnet, it cannot accept CMSG or DMSG sensors. For strokes at or over 300 mm, always use external guide rails to prevent side-load wear.
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 SAUJ80X100-75 FAQ
At 0.5 MPa it pushes 2513 N and pulls 2268 N. Push is 3518 N at 0.7 MPa and 4523 N at 0.9 MPa, with a theoretical max of 513 kgf at 1.0 MPa. The nominal 100 mm stroke is the maximum; the external stop screw lets you shorten the extend stroke by up to 75 mm on-site, yielding a 25 to 100 mm usable range.
An external stop screw physically limits the piston extension so you can set the end position without buying a new cylinder. This stop is not a load lock. A plain cylinder drifts on air loss, and the 28 mm adjustable cushion only decelerates near the end. For load holding, install an external rod lock or pilot-operated check valve.
