Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X25S
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X25S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 25mm 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 B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X25S
The B04-SAUD100X25S is an AirTAC double-acting, double-rod profile cylinder built for construction machinery. The B04- prefix marks this as the construction-machinery dedicated variant of the SAUD100X25S, mechanically identical to the base model. Its extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore, and because a rod exits both ends, the output force is equal in both directions at 3681 N each way at 0.5 MPa. It features a 1/2 inch port and a 25 mm stroke.
The rear protruding rod can carry a sensor cam or drive twin tools, while the included -S magnet enables CMSG, DMSG, or EMSG switches. For high-temperature environments, a Viton H seal option extends operation to 150 C.

Specifications follow the official AirTAC SAU series datasheet. Confirm against the product label before installation. Thread options: PT (blank) / G (BSPP). A high-temperature seal (0-150 °C) is available.
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 B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X25S Is Used
Excavator Valve Actuation
Drives twin valve stems with equal push and pull force on heavy equipment, ensuring precise hydraulic flow control without rotational drift.
Crane Load Stabilizer
Synchronizes heavy positioning arms on lifting machinery using its dual-rod anti-twist geometry to maintain rigid load alignment.
Rock Crusher Feed Gate
Opens and closes heavy material chutes on mobile crushers, using the back rod to trip an external limit switch in dirty environments.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X25S the Right Cylinder?
When sizing this 100 mm bore, which delivers 3681 N both ways at 0.5 MPa, stepping down to the 80 mm bore yields 2268 N. Stepping up is not available as 100 mm is the largest standard bore. Choose this double-rod configuration when your application demands anti-rotation guidance, synchronized twin-tool driving, or back-end switch tripping. Mounting is limited to Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. Because this SKU includes the -S magnet, you can directly mount reed or electronic sensors. For this 25 mm stroke, side-load stress is minimal, but any stroke over 300 mm requires external guide rails to prevent 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 B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD100X25S FAQ
The B04- prefix designates this as the construction-machinery dedicated variant of the SAUD100X25S, sharing identical specifications. Force is equal both ways because of the double rod: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. It never outputs a larger single-rod push value.
No, a plain cylinder drifts without live air and the adjustable air cushions only decelerate near stroke end without locking. For vertical lifting you must add an external rod lock or a pilot-operated check valve. The -S magnet allows position sensing via CMSG, DMSG, or EMSG switches.
