Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X750-50
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X750-50 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 750mm 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 SAUJ80X750-50
The AirTAC SAUJ80X750-50 is a double-acting, single-rod profile cylinder built for on-site stroke adjustment. An external stop screw lets you shorten the extend stroke by up to 50 mm, giving a usable working range of 700 to 750 mm. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 25 mm rod, M20x1.5 rod thread, and a 3/8" port.
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 design sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push figure), translating to a vertical lift capacity of about 128 kg with a 2:1 safety margin. Standard adjustable air cushions (28 mm) decelerate the payload smoothly. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X750-50 Is Used
Long-Reach Press Tending
Handles large fabricated parts where the exact push-off distance varies by 20 mm, using the stop screw to tune the extend endpoint on-site.
Variable-Format Diverters
Pushes mixed carton sizes on a packaging line, dialing in the 50 mm stroke reduction to accommodate different box widths without retooling.
Adjustable Pallet Stops
Acts as a high-force 2513 N end-stop for heavy pallets, allowing operators to shorten the stopping distance by up to 50 mm for different pallet depths.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X750-50 the Right Cylinder?
When sizing this actuator, look at both neighboring bores and the 0.5 MPa forces. Step down to a 63 mm bore for 1559 N push, or step up to a 100 mm bore for 3927 N push. Choose the SAUJ over a fixed SAU when your machine assembly needs final end-position tuning without buying new hardware. The 50 mm adjust window is ideal for resolving mechanical clearances. Mounting options include Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. Because this is a non-magnetized SKU, you cannot mount position sensors. With a 750 mm stroke, you must use external guides to prevent rod bending and manage side loads.
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 SAUJ80X750-50 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull force. At 0.7 MPa push is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical max is 513 kgf at 1.0 MPa. It uses a 3/8" port, a 25 mm rod, and 28 mm adjustable air cushions. The external stop screw allows shortening the 750 mm extend stroke by up to 50 mm.
No. The external stop screw only sets the end position; it is not a load lock. If air is lost or the valve is centered, the piston will drift. The air cushion solely decelerates the payload near the stroke end. To maintain a vertical load, install an external rod lock or a pilot-operated check valve.
