Airtac SAUJ100 Adjustable Cylinder SAUJ100X85-30
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X85-30 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 SAUJ100X85-30
The AirTAC SAUJ100X85-30 is a double-acting, double-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the working stroke by up to 30 mm, giving a usable range of 55 to 85 mm so you can fine-tune end positions without buying a new unit. It features a 1/2" port, an M20x1.5 rod thread, and 29 mm adjustable air cushions. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
The cylinder operates at 30-800 mm/s, and a high-temperature Viton H seal option extends the operating range from -20...+70 °C up to 150 °C.

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 SAUJ100X85-30 Is Used
Press Fit Tuning
Allows operators to dial in the exact 55 to 85 mm extend position for seating bearings without swapping physical spacers.
Variable Length Diverter
Adjusts the extend stop on-site to deflect varying package sizes on a packaging line by up to 30 mm.
Adjustable Product Stop
Sets a precise physical end-stop for different pallet widths, trimming the stroke to match the required gap.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X85-30 the Right Cylinder?
Choose the SAUJ over a fixed-stroke SAU when your machine assembly needs final end-position tuning within that 30 mm window. Mounting options include Basic, FA (flange), and LB (foot), with mounting compatibility matching the AirTAC SC series only. Because this stroke is under 300 mm, side-load guide concerns are minimal, but always guide the load. Note that this specific SKU lacks a magnet (no -S suffix), so it cannot accept CMSG/DMSG/EMSG sensors.
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 SAUJ100X85-30 FAQ
The nominal 85 mm extend stroke can be shortened by up to 30 mm on-site via an external stop screw, yielding a usable 55 to 85 mm range. It uses a 1/2" port and 29 mm adjustable cushions.
No. A plain SAUJ cylinder does not hold the load without live air, and the stop screw only sets the end position—it is not a load lock. The air cushion merely decelerates the piston near the end of the stroke. To maintain position during air loss, you must use an external rod lock or a pilot-operated check valve.
