Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X105-30
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X105-30 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 105mm 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 SAUJ80X105-30
The AirTAC SAUJ80X105-30 is a double-acting single-rod profile cylinder with an on-site extend stroke trim window of 30 mm. You can shorten the 105 mm nominal travel down to 75 mm using the external stop screw. It features a hard-anodized extruded aluminum barrel, making it shorter than an ISO 15552 unit of the same bore. The 3/8" port and M20x1.5 rod end handle robust pneumatics.
This 80 mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, peaking at 513 kgf at 1.0 MPa. A practical computed insight: expect a safe working load near 1508 N, or a 128 kg vertical lift with a 2:1 margin. It runs at 30-800 mm/s with 28 mm adjustable air cushions. Note this SKU lacks a magnet, so it cannot take sensors.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X105-30 Is Used
Press Fit Tuning
Allows operators to dial in the exact 75-105 mm extend position for pressing bearings without swapping cylinders.
Variable Carton Sealing
Adjusts the extend end-point on-site to accommodate different box heights on a shared packaging line.
End-Stop Calibration
Provides a compact profile solution for machinery needing precise mechanical end-position limits during commissioning.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X105-30 the Right Cylinder?
If you need less force, the 63 mm bore offers 1559 N push at 0.5 MPa; if you need more, the 100 mm bore provides 3927 N. Choose this SAUJ over a fixed SAU plus an external stop when you need built-in mechanical end-position tuning without adding external hardware. The 30 mm adjust window lets you fine-tune the extend stroke from 75 to 105 mm. Basic, FA flange, and LB foot mountings are available, sharing compatibility with the AirTAC SC series. Because this SKU has no -S magnet, you cannot mount CMSG or DMSG sensors. For this 105 mm stroke, side-load is minimal, but always guide the load for strokes over 300 mm.
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 SAUJ80X105-30 FAQ
At 0.5 MPa it pushes 2513 N and pulls 2268 N. Push is 3518 N at 0.7 MPa, 4523 N at 0.9 MPa, and 513 kgf max at 1.0 MPa. The external stop screw lets you shorten the 105 mm extend stroke by up to 30 mm, giving a usable range of 75-105 mm. It uses a 3/8" port.
The external stop screw mechanically sets the extend end position, but it is not a load lock. A plain cylinder drifts on air loss and the 28 mm cushions only decelerate near stroke end. For held loads, use an external rod lock or pilot-operated check valve. Also, this SKU lacks a magnet, so it cannot take sensors.
