Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-30
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-30 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 SAUJ80X100-30
The AirTAC SAUJ80X100-30 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 30 mm, yielding a usable 70-100 mm working window without buying a new unit. 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 push and 2268 N pull force at 0.5 MPa, peaking at 513 kgf at 1.0 MPa. The safe working load is roughly 1508 N, allowing a 128 kg vertical lift with a 2:1 margin. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore, and the SC-series compatible mounting includes Basic, FA, and LB options. Note this SKU lacks a magnet, so it cannot accept CMSG/DMSG/EMSG sensors.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-30 Is Used
Press Fit Tuning
Allows operators to dial in the exact 70-100 mm extend position for inserting bearings without swapping out the entire actuator.
Variable Length Diverter
Provides adjustable package deflection on a sorting line, letting maintenance shorten the extend stroke by up to 30 mm as box sizes change.
Adjustable Stop Gate
Sets a flexible physical end-stop for pallets, trimming the 100 mm stroke on-site to accommodate varying pallet overhang dimensions.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-30 the Right Cylinder?
Size this 80 mm bore against the neighboring 63 mm and 100 mm options. The 63 mm yields 1559 N push at 0.5 MPa, while the 100 mm hits 3927 N; this SAUJ80X100-30 provides 2513 N push at 0.5 MPa. Choose the 30 mm adjust window when your machinery setup needs precise extend-end tuning between 70 mm and 100 mm, which is simpler than machining a fixed SAU cylinder stop. Mount via FA flange or LB foot. Because this non-S SKU has no internal magnet, position sensing is impossible. For the 100 mm stroke, side-load is minimal, but always guide the load 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 SAUJ80X100-30 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull force, reaching 3518 N push at 0.7 MPa and 4523 N at 0.9 MPa. The theoretical maximum is 513 kgf at 1.0 MPa. The external stop screw allows you to shorten the 100 mm nominal extend stroke by up to 30 mm on-site, giving a usable 70-100 mm range.
The external screw mechanically sets the extend end position. It is not a load lock; the cylinder cannot hold a load on air loss and the 28 mm air cushion only decelerates the piston near the end. For secure load holding, add an external rod lock or pilot-operated check valve. Additionally, this non-S SKU lacks a magnet and cannot accept sensors.
