Airtac SAUJ100 Adjustable Cylinder SAUJ100X125-100
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X125-100 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 125mm 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 SAUJ100X125-100
The AirTAC SAUJ100X125-100 is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the working stroke by up to 100 mm, giving a usable extend range of 25-125 mm. The 125 mm nominal stroke serves as the maximum travel. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
This 100 mm bore generates 3927 N push and 3681 N pull at 0.5 MPa, peaking at 801 kgf at 1.0 MPa. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. For sizing, the safe working load is roughly 2356 N, and it can vertically lift about 200 kg with a 2:1 margin. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X125-100 Is Used
Variable Depth Pressing
Allows operators to dial in exact pressing depth on assemblies with varying part tolerances without changing cylinders.
Adjustable Flap Folding
Tunes the extend reach on carton folding mechanisms to perfectly handle different box heights on the fly.
Custom Stroke Stamping
Provides field flexibility for light stamping tasks where the material thickness frequently changes between production runs.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X125-100 the Right Cylinder?
Select this 100 mm bore for high-force needs, offering 5497 N push at 0.7 MPa. If your application requires less force, step down to the 80 mm bore which provides 2513 N push at 0.5 MPa. Choose the SAUJ over a fixed SAU when you need on-site travel tuning without buying a new cylinder. The 100 mm adjust window is ideal for prototyping or accommodating varying material thicknesses. Mounting options include Basic, FA flange, and LB foot, compatible with the AirTAC SC series. Since this non-S SKU lacks a magnet, position sensing is impossible. For the 125 mm stroke side-load is minimal, but for any stroke over 300 mm always use external guide rails. Remember the stop screw sets end position, not a load lock.
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 SAUJ100X125-100 FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull. Push force is 5497 N at 0.7 MPa, 7068 N at 0.9 MPa, and 801 kgf at 1.0 MPa. The external stop screw lets you shorten the extend stroke by up to 100 mm on-site, giving a usable range of 25-125 mm. The 1/2 inch port and 29 mm cushions are fixed by the bore.
The external stop screw mechanically limits the piston extension, letting you trim travel without disassembling the cylinder. This stop only sets the end position; it is not a load lock. A plain cylinder drifts on air loss and the cushion only decelerates. For secure load holding, install an external rod lock or pilot-operated check valve.
