Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X195-50S
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X195-50S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 195mm 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 SAUJ80X195-50S
The AirTAC SAUJ80X195-50S is a double-acting, single-rod profile cylinder with an on-site extend-stroke adjustment window of 50 mm. You can trim the usable extend travel down from the 195 mm maximum to a minimum of 145 mm via the external stop screw, allowing precise positioning without buying a new actuator. It features a 3/8" port, an M20x1.5 rod thread, and 28 mm adjustable air cushions at each end. The extruded aluminum profile barrel makes this unit shorter than an ISO 15552 cylinder of the same bore.
In the 80 mm bore class, this actuator generates 2513 N of push force and 2268 N of pull force at 0.5 MPa, reaching a maximum theoretical output of 513 kgf at 1.0 MPa. For reliable sizing, the safe working load is approximately 1508 N (about 60% of the 0.5 MPa push figure), translating to a vertical lift capacity of roughly 128 kg with a 2:1 safety margin. Because this SKU includes the -S magnet option, it directly supports CMSG, DMSG, and EMSG sensors for position detection.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X195-50S Is Used
Variable Depth Forming Press
Allows operators to dial in the exact 145 to 195 mm extend depth on-site for different material thicknesses without changing out the entire actuator assembly.
Adjustable Transfer Pusher
Tunes the extend stroke by up to 50 mm to accommodate varying package sizes on a packaging line, ensuring precise placement at the end of the conveyor.
Custom Height Pallet Stopper
Provides a field-adjustable mechanical end stop for pallets of varying heights, utilizing the 2513 N push force to halt heavy loads reliably.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X195-50S the Right Cylinder?
When sizing this 80 mm bore actuator, compare it against the neighboring 63 mm and 100 mm options. The 63 mm bore provides 1559 N push at 0.5 MPa, while the 100 mm bore offers 3927 N at the same pressure, so choose the 80 mm bore when your application requires the 2513 N intermediate thrust. Select the SAUJ adjustable-stroke version over a fixed SAU cylinder when your machine assembly requires field-tuning of the extend end-position; the 50 mm window here lets you dial in the exact 145 to 195 mm travel on-site. Mounting is compatible with AirTAC SC series accessories using Basic, FA flange, or LB foot brackets. The included -S magnet allows for electronic or reed switch integration. For this 195 mm stroke, ensure external guide rails are used to prevent excessive side-loading on the rod. Remember that the external stop screw sets the end position but does not function as a load lock; if air pressure is lost, the piston will drift, so utilize an external rod lock or pilot-operated check valve for suspended loads.

- ✓ 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 SAUJ80X195-50S FAQ
This 80 mm bore cylinder features a 50 mm adjustment window, allowing you to shorten the extend stroke from the 195 mm maximum down to 145 mm. It provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a maximum theoretical force of 513 kgf at 1.0 MPa. It operates at 30-800 mm/s and uses a 3/8" port.
An external stop screw physically limits the piston's extend travel, letting you set the exact end position within the 50 mm window on-site. The -S suffix indicates a built-in piston magnet, enabling the use of CMSG, DMSG, or EMSG switches for position sensing. Note that the stop screw only sets the end position; it is not a load lock, and the cylinder requires an external rod lock to hold a load without live air pressure.
