Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X105-40S
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X105-40S 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 SAUJ80X105-40S
The AirTAC SAUJ80X105-40S 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 40 mm, yielding a usable range of 65-105 mm from the 105 mm maximum. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 3/8" port, an M20x1.5 rod thread, and 28 mm adjustable air cushions.
This 80 mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, scaling to 4523 N at 0.9 MPa. The -S suffix indicates a built-in magnet for CMSG, DMSG, or EMSG sensors. For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push force), translating to a 128 kg vertical lift with a 2:1 safety margin. The stop screw dictates end position but does not lock the load; use an external rod lock for holding.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X105-40S Is Used
Press Stroke Calibration
Perfect for light stamping stations where the 40 mm stop screw dials in the exact contact pressure on varying material thicknesses without changing tooling.
Variable Length Diverter
Sorts mixed package sizes on a line by adjusting the extend stroke on-site to match specific box dimensions for precise routing.
Adjustable Sealing Jaw
Accommodates different pouch widths in a vertical fill machine, using the 65-105 mm stroke window to set the correct sealing gap.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X105-40S the Right Cylinder?
When sizing this unit, look at both neighbors: the 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore hits 3927 N. Choose this 80 mm model for loads needing around 1508 N of safe working force. Pick the SAUJ over a fixed SAU when your machine assembly requires slight extend-length tuning without buying a new cylinder. The 40 mm adjust window is ideal for final mechanical timing. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. Because it has the -S suffix, you can directly mount CMSG or DMSG sensors. For this 105 mm stroke, side-load is minimal, but for any stroke over 300 mm, always use external guide rails to prevent piston binding.
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 SAUJ80X105-40S FAQ
This 80 mm bore cylinder provides 2513 N push and 2268 N pull at 0.5 MPa, 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 105 mm extend stroke can be shortened by up to 40 mm via the external stop screw, giving a usable range of 65-105 mm. It uses a 3/8" port and 28 mm adjustable cushions.
The -S suffix means it has a built-in piston magnet for mounting CMSG, DMSG, or EMSG electronic switches. The stop screw only sets the extend end position; it is not a load lock. The cylinder will drift on air loss because the air cushion only decelerates the piston near the end of the stroke. For true load holding, install an external pilot-operated check valve or rod lock.
