Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-50S
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-50S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 1000mm 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 SAUJ80X1000-50S
The AirTAC SAUJ80X1000-50S is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the working stroke by up to 50 mm, giving a usable extend range of 950 to 1000 mm. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. This -S variant includes a piston magnet for CMSG, DMSG, or EMSG position switches.
This 80 mm bore uses a 3/8" port and a 25 mm rod. It delivers 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa. For sizing, the safe working load is roughly 1508 N (60 percent of the 0.5 MPa push), and it can vertically lift about 128 kg with a 2:1 safety margin. Viton H seals can raise the operating temperature to 150 C.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-50S Is Used
Long-Reach Pressing
Apply 2513 N of push force at 0.5 MPa for pressing components, using the 50 mm stop screw to fine-tune the exact 950-1000 mm extend depth on-site.
Adjustable Lowering Stop
Lower heavy fixtures with a 128 kg vertical lift capacity, tweaking the end position to accommodate varying material thicknesses without reprogramming valves.
Extended Transfer Diversion
Divert products along a wide conveyor belt, using the magnetic piston to confirm the full 1000 mm extend position before retracting the actuator.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X1000-50S the Right Cylinder?
When sizing this unit, look at the neighboring bores: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. The 80 mm bore hits 2513 N push, making it ideal for medium-heavy tasks. Choose the SAUJ over a fixed SAU when you need final end-position tuning during machine commissioning without swapping hardware. Basic, FA, and LB mounts are available. Because the 1000 mm stroke is long, use external guides to prevent rod bending and manage side loads. The -S magnet enables electronic sensing, but remember the stop screw sets position only; it is not a load lock.
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 SAUJ80X1000-50S FAQ
This 80 mm bore cylinder has a 3/8" port and a 25 mm rod. It generates 2513 N push and 2268 N pull at 0.5 MPa, 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 extend stroke by up to 50 mm, providing a usable range of 950 to 1000 mm.
The -S suffix means a magnet is built into the piston for CMSG, DMSG, or EMSG sensors. The external stop screw mechanically limits the extend stroke, letting you trim the end position on-site. This stop is not a load lock; the cylinder does not hold a load without live air, and the cushion only decelerates. For load holding on air loss, use an external rod lock or pilot-operated check valve.
