Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD63X250
The AirTAC B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD63X250 is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 250mm stroke, 3/8" 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-SAUD63X250
The B04-SAUD63X250 is AirTAC's construction-machinery dedicated variant of the SAUD63X250 double-rod cylinder. The B04- prefix designates it for heavy-equipment builders, but it remains mechanically identical to the base model. Because a rod exits both ends of the hard-anodized aluminum profile barrel, the push and pull forces are perfectly equal at 1402 N each way at 0.5 MPa. This profile design is notably shorter than an ISO 15552 cylinder of the same bore.
With a 63 mm bore and 250 mm stroke, it features a 3/8" port, an M16x1.5 rod thread, and adjustable air cushions at both ends. Because this SKU lacks the -S magnet option, it cannot accept magnetic switches.

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | — |
| Max (@1.0 MPa) | 286 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-SAUD63X250 Is Used
Excavator Panel Pusher
Drives cabin control panels on earthmoving equipment with equal push and pull force, preventing twist during assembly.
Crane Component Sync
Synchronizes two tooling heads on heavy-equipment fixtures using the twin-rod anti-rotation profile.
Loader Arm Test Rig
Cycles loader linkage components with 1402 N both ways, fitting a compact profile into tight machinery cells.
Is the Airtac B04-SAUD Construction Machinery Dedicated Standard Cylinder B04-SAUD63X250 the Right Cylinder?
When sizing this double-acting cylinder, compare both ways: stepping down to the 50 mm bore yields 825 N each way at 0.5 MPa, while stepping up to the 80 mm bore provides 2268 N. Choose this double-rod configuration when your application demands anti-rotation guidance, synchronized twin-tool driving, or a back rod to trip a mechanical switch. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because the 250 mm stroke exceeds 300 mm? Actually at 250 mm it is borderline, but always support external side loads with a guide to prevent binding. Note that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for secure load holding.
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-SAUD63X250 FAQ
The B04- prefix marks this as AirTAC's construction-machinery dedicated line of the SAUD63X250; mechanically the specs are identical. Force is equal both ways because rods protrude from both ends: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. It uses a 3/8" port.
No. This specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG magnetic switches. If you require position sensing, select the -S version. The back rod can still trip an external mechanical switch if needed.
