Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-100
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-100 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 100mm 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 SAUJ80X100-100
The AirTAC SAUJ80X100-100 is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the 100 mm nominal stroke by up to 100 mm, dropping the usable extend travel to 0 mm for exact machine setup. The extruded aluminum profile barrel keeps the unit more compact than an ISO 15552 cylinder of the same bore. It features a 3/8 inch 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, peaking at 513 kgf at 1.0 MPa. A practical computed insight: the safe working load is roughly 1508 N, and it can vertically lift about 128 kg with a 2:1 safety margin. Standard temperature ranges from -20 to +70 C, while a Viton H seal option extends this to 150 C. Because this SKU lacks a magnet, it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-100 Is Used
Variable Press Stroke
Ideal for light presses needing different material crush depths. Turn the external stop screw to dial in the exact extend endpoint for each batch without swapping tooling.
Adjustable Diverter Arm
Perfect for routing varying package sizes on a line. Shorten the extend travel on-site to match box dimensions precisely, ensuring gentle but firm contact.
Custom Fold Mechanism
Useful for carton erecting where fold depth changes. The 100 mm trim window allows operators to set the perfect forming position quickly during product changeovers.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-100 the Right Cylinder?
When sizing this unit, look both ways: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore offers 3927 N. The 80 mm bore hits 2513 N push and 3518 N at 0.7 MPa, making it a strong mid-range choice. Choose this SAUJ model over a fixed SAU when you need field tuning without buying a new cylinder. The 100 mm adjust window provides maximum flexibility for prototyping or varying product sizes. Mounting options include Basic, FA flange, and LB foot, compatible with the AirTAC SC series. For strokes at or over 300 mm, always use an external guide to prevent side-load wear. Note this non-magnetic SKU cannot accept position sensors.
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 SAUJ80X100-100 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull force. Push increases to 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 100 mm extend stroke can be shortened by up to 100 mm via an external stop screw, yielding a usable extend range of 0 to 100 mm. It uses a 3/8 inch port and 28 mm adjustable cushions.
No, the stop screw only sets the end position; it is not a load lock. A plain double-acting cylinder drifts when air is lost, and the cushion solely decelerates the piston near stroke end. To hold a load securely, you must add an external rod lock or a pilot-operated check valve. Also, because this SKU lacks a magnet, it cannot mount magnetic sensors.
