Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X950-40
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X950-40 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 950mm 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 SAUJ80X950-40
The AirTAC SAUJ80X950-40 is a double-acting, single-rod profile cylinder with an on-site extend stroke adjustment window of 40 mm. You can trim the usable extend stroke from 950 mm down to 910 mm using the external stop screw. This bore delivers 2513 N push and 2268 N pull at 0.5 MPa, with a 3/8" port and M20x1.5 rod thread. The extruded aluminum profile keeps the body shorter than an ISO 15552 cylinder of the same bore.
For sizing, the safe working load is roughly 1508 N (about 60% of the 0.5 MPa push force), and it can vertically lift around 128 kg with a 2:1 safety margin. The adjustable air cushions span 28 mm. This plain SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. If you need to hold a load vertically without live air, add an external rod lock, as the cushion only decelerates.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X950-40 Is Used
Transfer Line Diverter
Tune the 950 mm extend stroke by up to 40 mm on-site to match varying product lengths without changing the cylinder.
Pallet Stopper Gate
Adjust the end position precisely for different pallet widths, using the 80 mm bore to push heavy loads reliably.
Long-Reach Forming Press
Trim the extend stroke to set the exact material contact depth, relying on the 28 mm cushions for smooth deceleration.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X950-40 the Right Cylinder?
Choose this 80 mm bore if the 63 mm class (2182 N push at 0.7 MPa) is insufficient, or step down from 100 mm if you do not need 5497 N. The 40 mm adjust window lets you fine-tune the extend end position without buying a new cylinder, which is more compact than fitting a fixed SAU with an external mechanical stop. Basic, FA, and LB mountings are available, sharing compatibility with the AirTAC SC series. Because this is a non-magnetized SKU, you cannot mount position sensors. At 950 mm, the rod is highly susceptible to bending; always use an external guide to prevent side loads and premature seal wear.
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 SAUJ80X950-40 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. Push force is 3518 N at 0.7 MPa and 4523 N at 0.9 MPa, with a max of 513 kgf at 1.0 MPa. The nominal stroke is 950 mm, and the external stop screw lets you shorten the extend stroke by up to 40 mm on-site, giving a usable range of 910 to 950 mm.
No to both. The stop screw sets the end position but is not a load lock; without live air the piston drifts, so use an external rod lock or pilot-operated check valve for holding. Also, this SKU lacks a magnet, meaning CMSG, DMSG, or EMSG sensors cannot be installed.
