Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X210-100
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X210-100 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 210mm 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 SAUJ80X210-100
The AirTAC SAUJ80X210-100 is a double-acting, single-rod profile cylinder with an on-site extend-stroke adjustment window of 100 mm. You can trim the 210 mm nominal extend down to a 110 mm usable length via the external stop screw. It features a 3/8" port and an M20x1.5 rod thread.
This 80 mm bore generates 2513 N push and 2268 N pull at 0.5 MPa, peaking at 513 kgf. 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. It offers FA and LB mounting, plus Viton H seals for up to 150 C.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X210-100 Is Used
Press Fit Tuning
Dialing in precise insertion depths on an assembly line where the 100 mm stop screw window handles varying part tolerances without custom shims.
Variable Length Diverters
Adjusting a diverting flap stroke on a packaging conveyor to accommodate different carton sizes on the fly using the external stop.
Adjustable Stops
Acting as a movable end-stop for incoming goods, allowing operators to shorten the extend stroke precisely when reconfiguring the line layout.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X210-100 the Right Cylinder?
For sizing both ways: stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to 100 mm provides 3927 N. Choose this SAUJ over a fixed SAU when your machine build requires on-site extend length tuning without buying a new cylinder. The 100 mm adjust window is ideal for dialing in exact end positions. Use FA or LB mounts; side-load guides are recommended for longer strokes. Note this SKU lacks the -S magnet, so it cannot accept CMSG or DMSG 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 SAUJ80X210-100 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. Push rises to 3518 N at 0.7 MPa and 4523 N at 0.9 MPa, with a 513 kgf max at 1.0 MPa. The 210 mm nominal extend stroke can be shortened by up to 100 mm on-site, giving a 110 to 210 mm usable range.
An external stop screw physically sets the extend end position. This stop is not a load lock; the cylinder will drift on air loss and the 28 mm air cushion only decelerates the piston near the end. For secure load holding, install an external rod lock or pilot-operated check valve. This non-S SKU also cannot accept magnetic sensors.
