Airtac SAUJ100 Adjustable Cylinder SAUJ100X85-20S
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X85-20S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 85mm 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 SAUJ100X85-20S
The AirTAC SAUJ100X85-20S is a double-acting double-rod profile cylinder with an on-site stroke adjustment window. An external stop screw lets you trim the extend stroke by up to 20 mm, giving a usable working stroke of 65 to 85 mm. It features a 1/2 inch port and a built-in piston magnet for position sensing.
The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same size.

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 SAUJ100X85-20S Is Used
Press Fit Tuning
Allows operators to dial in the exact 65 to 85 mm insertion depth for delicate bearing presses without swapping hardware.
Variable Diverter Stroke
Adjusts the extend stop on the fly to accommodate different package widths on a sorting line.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X85-20S the Right Cylinder?
The 20 mm adjust window is ideal when final machinery positions vary, letting you fine-tune the 65 to 85 mm extend length without buying a new cylinder. Basic, FA, and LB mountings are available, sharing compatibility with the AirTAC SC series. The -S suffix means a magnet is included for CMSG, DMSG, or EMSG sensors. For strokes at or over 300 mm, always use external guide rails to prevent side-load 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 SAUJ100 Adjustable Cylinder SAUJ100X85-20S FAQ
Push force rises 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 external stop screw shortens the extend stroke by up to 20 mm, yielding a usable 65 to 85 mm stroke. It uses a 1/2 inch port.
The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG electronic or reed switches. Note that a plain cylinder does not hold load on air loss; the piston drifts and the cushion only decelerates. For a locked load, use an external rod lock or pilot-operated check valve.
