Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-10
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-10 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 850mm stroke, 1/2" 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 SAUJ100 Adjustable Cylinder SAUJ100X850-10
The AirTAC SAUJ100X850-10 is a double-acting, single-rod profile cylinder with an 850 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable range of 840-850 mm. This allows precise end-position tuning without buying a new cylinder. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same 100 mm bore. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
This 100 mm bore delivers substantial force: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N push at 0.9 MPa. For sizing, the safe working load is roughly 2356 N (60% of the 0.5 MPa push figure), and it can manage a 200 kg vertical lift with a 2:1 margin. The cylinder operates at 30-800 mm/s. Note this SKU lacks a magnet (-S), so it cannot accept CMSG or DMSG sensors. For high-heat environments up to 150 C, Viton H seals are available.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-10 Is Used
Heavy Press Tonnage
Demands high push force to form thick materials, needing minor extend stroke tuning to set precise bottom dead center.
Large Pallet Diverting
Requires a long reach and high force to index heavy pallets, with field adjustment to compensate for diverter wear.
Bulk Container Gating
Needs robust holding power to control heavy tote flow, allowing 10 mm extend tweaks for varying container widths.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-10 the Right Cylinder?
When sizing this actuator, compare it against the neighboring 80 mm bore, which provides 2513 N push at 0.5 MPa. The 100 mm bore chosen here yields 3927 N push at 0.5 MPa, ensuring ample force for heavy loads. Choose this SAUJ model over a fixed-stroke SAU when your assembly requires minor on-site adjustments to the extend end position; the 10 mm stop screw window is perfect for dialing in exact alignment without adding external stops. Mounting options include Basic, FA flange, and LB foot styles, with mounting compatibility matching the AirTAC SC series. Because this is a non-magnetized SKU, you cannot mount position sensors. Given the long 850 mm stroke, you must use external guides to prevent rod bending and manage side loads. Operating pressure is 0.15-1.0 MPa.
Quick checklist

- ✓ 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 SAUJ100 Adjustable Cylinder SAUJ100X850-10 FAQ
This 100 mm bore cylinder has a 1/2 inch port and a maximum stroke of 850 mm. The external stop screw allows you to shorten the extend stroke by up to 10 mm on-site, giving a usable range of 840-850 mm. Force output is 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N push at 0.9 MPa. The theoretical maximum force is 801 kgf at 1.0 MPa.
No. A plain SAUJ cylinder does not hold its load on air loss or when the valve is centered; the piston will drift. The 10 mm external stop screw only sets the extend end position, and the 29 mm air cushions only decelerate the piston near stroke end. Neither feature acts as a load lock or brake. To hold a load securely, you must use an external rod lock or a pilot-operated check valve.
