Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-20
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X850-20 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 SAUJ100X850-20
The AirTAC SAUJ100X850-20 is a double-acting double-rod profile cylinder with an 850 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, yielding a usable range of 830-850 mm. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
It operates at 30-800 mm/s. Note this SKU lacks a magnet, so it cannot take CMSG or DMSG sensors. For high-heat environments up to 150 C, specify the Viton H seal option.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-20 Is Used
Large Door Opening Mechanisms
Provides the heavy thrust needed for industrial doors, with the 20 mm stop screw allowing precise field tuning of the final open position.
Heavy Pallet Diverters
Pushes substantial loads along a conveyor, where the adjustable end position accommodates slight variations in pallet dimensions.
Vertical Material Lifts
Handles vertical lifting tasks requiring high force, letting operators dial in the exact raise height during installation.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-20 the Right Cylinder?
Choose the SAUJ over a fixed SAU when your machine assembly needs minor 0-20 mm extend length tweaking without buying a new cylinder. Mounting options include Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. Because the 850 mm stroke is long, always use external guides to prevent rod bending and manage side loads. This non-magnet SKU cannot accept sensors; if you need position detection, select a -S model instead.
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 SAUJ100 Adjustable Cylinder SAUJ100X850-20 FAQ
Push increases to 5497 N at 0.7 MPa and 7068 N at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The nominal 850 mm extend stroke can be shortened by up to 20 mm on-site using the external stop screw, giving a usable range of 830-850 mm.
No. A plain cylinder drifts on air loss or when the valve is centered; the 29 mm air cushion only decelerates near the end of travel and the stop screw only sets the end position. For load holding, use an external rod lock or pilot-operated check valve. Additionally, this SKU has no magnet and cannot accept CMSG or DMSG sensors.
