Airtac SAUJ100 Adjustable Cylinder SAUJ100X70-50S
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X70-50S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 70mm 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 SAUJ100X70-50S
The AirTAC SAUJ100X70-50S is a double-acting, double-rod profile cylinder with an on-site stroke adjustment window. An external stop screw lets you shorten the extend stroke by up to 50 mm, giving a usable working stroke of 20 to 70 mm for exact end-position tuning. It features a 1/2" port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. The -S suffix means a built-in magnet supports CMSG, DMSG, or EMSG sensors, and Viton H seals can raise the temperature limit 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 SAUJ100X70-50S Is Used
Press Fit Tuning
Allows operators to dial in the exact 20 to 70 mm extend position for inserting bearings without changing hard stops.
Variable Depth Sealing
Adjusts the extend stroke on-site to accommodate different box heights or sealing head depths on the fly.
Prototyping Fixtures
Provides a 50 mm adjustment window to test multiple extend endpoints during new product design validation.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X70-50S the Right Cylinder?
Choose the SAUJ over a fixed SAU when your assembly requires field tuning of the extend end without buying multiple units. The 50 mm adjust window is ideal for prototyping or absorbing mechanical tolerances. Mounting options include Basic, FA flange, and LB foot, compatible with the AirTAC SC series. The -S magnet enables electronic or reed switching. For strokes over 300 mm, always use external guide rails to prevent side-load wear, though this 70 mm unit is compact. Note the external stop sets position only; it is 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 SAUJ100X70-50S FAQ
The theoretical max is 801 kgf at 1.0 MPa. The external stop screw allows you to shorten the 70 mm extend stroke by up to 50 mm, yielding a 20 to 70 mm usable window.
The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG position sensors. A plain cylinder does not hold load on air loss; the piston drifts and the cushion only decelerates. For held loads, use an external rod lock or pilot-operated check valve.
