Airtac SAUJ100 Adjustable Cylinder SAUJ100X85-50
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X85-50 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 SAUJ100X85-50
The AirTAC SAUJ100X85-50 is a double-acting double-rod profile cylinder with an on-site extend stroke adjustment. An external stop screw lets you trim the working stroke by up to 50mm, yielding a usable range of 35-85mm. The 85mm nominal length serves as the maximum travel. It features a 1/2 inch port, an M20x1.5 rod thread, and 29mm adjustable air cushions.
The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. Note this SKU lacks a magnet, so it cannot accept position sensors.

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 SAUJ100X85-50 Is Used
Press Fit Tuning
Allows operators to dial in the exact 35-85mm extend position for pressing bearings, compensating for material tolerances on-site.
Variable Depth Sealing
Adjusts the extend stroke on packaging lines to seal boxes of different heights without changing out the entire actuator.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X85-50 the Right Cylinder?
Choose the SAUJ over a fixed SAU cylinder when your machine assembly requires field-tuning the extend end position without buying new hardware. The 50mm adjust window is ideal for prototyping or accommodating varying material thicknesses. Mounting options include Basic, FA flange, and LB foot, matching the AirTAC SC series footprint. Because this specific SKU has no -S magnet, it cannot support CMSG or DMSG sensors. For any stroke length, ensure external guides handle side loads to prevent piston binding.
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 SAUJ100X85-50 FAQ
Push force increases to 5497N at 0.7MPa and 7068N at 0.9MPa, with a theoretical max of 801kgf at 1.0MPa. The 85mm nominal stroke is the maximum travel; an external screw lets you shorten the extend stroke by up to 50mm on-site, giving a usable range of 35-85mm.
This SKU lacks a magnet, so it cannot accept magnetic position sensors. Regarding load holding, the cylinder does not hold a load on air loss; the piston drifts and the 29mm air cushion only decelerates near the stroke end. The external stop screw sets the end position but is not a load lock. For secure vertical holding, use an external rod lock or a pilot-operated check valve.
