Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X120-10
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X120-10 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 120mm 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 SAUJ80X120-10
The AirTAC SAUJ80X120-10 is a double-acting, single-rod profile cylinder with an on-site extend stroke trim of up to 10 mm via an external stop screw. You get a usable stroke range of 110-120 mm, letting you dial in the exact end position without buying a new actuator. The extruded aluminum barrel is noticeably shorter than an ISO 15552 cylinder of the same bore, saving machine space. It features a 3/8" port, an M20x1.5 rod thread, and 28 mm adjustable air cushions at each end.
This 80 mm bore generates 2513 N of push force and 2268 N of pull force at 0.5 MPa, peaking at a theoretical 513 kgf at 1.0 MPa. For sizing, a safe working load is roughly 1508 N (about 60% of the 0.5 MPa push figure), translating to a vertical lift capacity of about 128 kg with a 2:1 safety margin. The unit operates at 30-800 mm/s and accepts basic, FA flange, or LB foot mounts. Note this specific SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X120-10 Is Used
Press Fit Tuning
Dial in the exact 110-120 mm insertion depth for bearing presses on-site using the stop screw, ensuring perfect seating without reordering actuators.
Dynamic Divert Stops
Adjust the extend endpoint by up to 10 mm to accommodate varying package sizes on a conveyor line without changing out the entire cylinder assembly.
Pallet Clamping
Fine-tune the clamping contact point on mixed-height pallets, using the 2513 N push force to secure loads while compensating for minor height variations.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X120-10 the Right Cylinder?
When sizing this actuator, look at both the adjacent bores and the force at 0.5 MPa. The 63 mm bore yields 1559 N push, while the 100 mm bore provides 3927 N; this 80 mm actuator delivers 2513 N, making it ideal for medium-heavy tasks. Choose the SAUJ over a fixed SAU when your assembly requires minor end-position tweaking after installation, saving you the cost of machining external hard stops. The 10 mm adjust window is perfect for fine-tuning clamping or pressing depth. Mount using basic, FA, or LB brackets, which share compatibility with the AirTAC SC series. Because this SKU lacks the -S magnet, you cannot mount magnetic switches; if you need position sensing, select a -S variant. For this 120 mm stroke, side-load is minimal, but for any stroke over 300 mm, always use external guide rails to prevent rod 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 SAUJ80X120-10 FAQ
This 80 mm bore cylinder provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N at 0.9 MPa, and a max of 513 kgf at 1.0 MPa. The nominal 120 mm extend stroke can be shortened by up to 10 mm on-site via the external stop screw, giving a usable range of 110-120 mm. The stop screw sets the end position but is not a load lock.
No to both. A plain cylinder drifts on air loss or when the valve is centered; the 28 mm air cushions only decelerate the piston near stroke end and do not function as a brake. For load holding, install an external rod lock or pilot-operated check valve. Additionally, this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.
