Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X110-30
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X110-30 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 110mm 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 SAUJ80X110-30
The AirTAC SAUJ80X110-30 is a double-acting single-rod profile cylinder with an 80 mm bore and a 110 mm maximum extend stroke. An external stop screw lets you trim the extend stroke on-site by up to 30 mm, yielding a usable working window of 80 to 110 mm. The extruded aluminum profile 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 at each end.
This bore delivers a push force of 2513 N and a pull force of 2268 N 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 128 kg with a 2:1 margin. This base SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. A Viton H seal option raises the operating temperature from 70 C up to 150 C.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X110-30 Is Used
Variable Depth Forming
Stamping or pressing operations where the material thickness fluctuates, requiring the 30 mm external stop to fine-tune the final extend position on-site.
Adjustable Transfer Stops
Diverting different package heights on a line by dialing the stop screw to set the exact 80 to 110 mm protrusion needed for each run.
Tiered Pallet Positioning
Lowering loads onto pallets of varying heights where the final resting position must be precisely set without re-plumbing the pneumatic system.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X110-30 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. Choose the SAUJ over a fixed SAU when you need on-site extend length tuning without buying a new cylinder. The 30 mm adjust window is ideal for final machine timing or accommodating varied part sizes. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. Because this SKU lacks the -S magnet, it cannot support position sensing. For any stroke over 300 mm, ensure external guiding to prevent side-load damage. Operating speed spans 30-800 mm/s.
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 SAUJ80X110-30 FAQ
This 80 mm bore cylinder has a 3/8" port and a maximum 110 mm stroke that you can shorten by up to 30 mm on-site (usable extend 80-110 mm). It 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 513 kgf maximum at 1.0 MPa. It uses an M20x1.5 rod thread with 28 mm adjustable air cushions.
No. The external stop screw only sets the end position of the extend stroke; it is not a load lock. If air is lost or the valve is centered, the piston will drift. The 28 mm air cushion only decelerates the moving load near the end of travel. To safely hold a load, you must add an external rod lock or a pilot-operated check valve.
