Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X105-50
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X105-50 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 SAUJ80X105-50
The AirTAC SAUJ80X105-50 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 50 mm, yielding a usable range of 55-105 mm from the 105 mm maximum. 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, scaling to 4523 N at 0.9 MPa. A practical computed insight: the safe working load is roughly 1508 N, allowing a vertical lift of about 128 kg with a 2:1 margin. The unit operates at 30-800 mm/s. Since this SKU lacks the -S magnet option, it cannot accept magnetic switches. For high-heat environments up to 150 C, Viton H seals are available.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X105-50 Is Used
Press Fit Tuning
Allows operators to dial in the exact 55-105 mm extend distance for seating bearings without swapping out the entire actuator.
Variable Package Diverter
Adjusts the pusher stroke on-site to handle different carton widths on a packaging line, ensuring precise routing.
Adjustable End Stop
Sets a firm mechanical end position for palletizing stops, fine-tuning the 50 mm window to match varying pallet depths.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X105-50 the Right Cylinder?
When sizing this actuator, look at the neighboring bores: the 63 mm yields 1559 N push at 0.5 MPa, while the 100 mm provides 3927 N. The SAUJ80X105-50 hits a solid middle ground at 2513 N. Choose the SAUJ adjustable type over a fixed SAU when your machine build requires field-tuning of the end position without buying new hardware. The 50 mm adjust window is ideal for dialing in exact clamping or pressing distances. Mounting options include Basic, FA flange, and LB foot, with compatibility matching the AirTAC SC series. Because this is a non-magnetized SKU, position sensing is not possible. For this 105 mm stroke, side-load is minimal, but for any stroke over 300 mm, always use external guide rails to prevent rod binding.

- ✓ 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 SAUJ80X105-50 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull, reaching 3518 N at 0.7 MPa, 4523 N at 0.9 MPa, and a theoretical max of 513 kgf at 1.0 MPa. The nominal 105 mm extend stroke can be shortened by up to 50 mm via the external stop screw, giving a usable 55-105 mm range. The 3/8" port and 28 mm cushions are fixed by the 80 mm bore.
No, the stop screw only sets the end position and the air cushion solely decelerates the piston near the end of travel; neither acts as a load lock. If air is lost, the piston will drift. To maintain position, you must add an external rod lock or a pilot-operated check valve.
