Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-10
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-10 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 SAUJ80X100-10
The AirTAC SAUJ80X100-10 is a double-acting, single-rod profile cylinder with an on-site extend stroke adjustment window of 10 mm. You can trim the usable extend stroke from 100 mm down to 90 mm via an external stop screw. It features a 3/8" port, an M20x1.5 rod thread, and 28 mm adjustable air cushions. 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, reaching 4523 N at 0.9 MPa. A practical computed insight: the safe working load is roughly 1508 N (60% of the 0.5 MPa push force), translating to a vertical lift capacity of about 128 kg with a 2:1 margin. Choose this adjustable model over a fixed SAU cylinder when you need final position tuning without machining external stops.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-10 Is Used
Press Fit Tuning
Final press depth varies by material tolerance; the 10 mm stop screw lets operators dial in the exact extend position on the assembly line.
Diverter Gate Adjustment
Calibrate the extend stop to alter the gate angle precisely, accommodating different package sizes without changing the cylinder.
Sealing Head Setup
Fine-tune the downward extend stroke by up to 10 mm to achieve consistent sealing pressure across varying carton thicknesses.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-10 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 yields 3927 N. The SAUJ80X100-10 hits 2513 N, making it ideal when 63 mm lacks thrust. The 10 mm adjust window is perfect for minor end-position tweaks rather than major travel changes. Basic, FA flange, and LB foot mountings are available, compatible with the AirTAC SC series. This SKU lacks a magnet (-S), so it cannot accept CMSG or DMSG sensors. For the 100 mm stroke, side-load is minimal, but always guide the load for strokes over 300 mm. Operating pressure is 0.15-1.0 MPa.
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 SAUJ80X100-10 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 nominal 100 mm extend stroke can be shortened by up to 10 mm on-site, yielding a 90-100 mm usable range. It uses a 3/8" port.
No. The external stop screw only sets the end position; it is not a load lock. Without live air, the piston drifts and the 28 mm air cushion only decelerates near stroke end. For secure load holding, install an external rod lock or a pilot-operated check valve.
