Automation rotary tables and indexing stations require clean, repeatable pneumatic transfer for clamping, vacuum, blow-off, grippers, and actuator control. Begapunk provides standard and custom multi-passage air rotary unions for machine builders.
On a rotary indexing table, multiple fixtures may need air at different times. A rotary union allows the machine to supply pneumatic functions while keeping hoses organized and preventing twist damage.
The best model depends on passage count, station count, pressure, rotation speed, allowable leakage, and whether the rotary union must share space with wiring, sensors, or a slip ring.
Typical requirement2 to 8 passages for clamping, vacuum, blow-off, and separated station control.Map each pneumatic function before selecting the model. Adding one spare passage can simplify future tooling changes.
Confirm whether the table rotates continuously, indexes step by step, or stops at fixed dwell positions.
Some systems need air plus electrical signals. In that case, a pneumatic-electric design or separate slip ring arrangement may be required.
| Station Type | Common Function | Selection Focus | Begapunk Direction |
|---|---|---|---|
| Small indexing table | Clamp, release, blow-off | 2 to 3 passages, compact body, easy mounting | BP-2P or BP-3P family |
| Multi-station carousel | Several independent air lines | 4 to 8 passages, low leakage, stable support | BP-4P, BP-8P, custom |
| Sensor-equipped station | Air plus electrical signal routing | Air channels and signal separation | BP-3P-S06 or custom pneumatic-electric design |
Send your station count, pneumatic circuit, pressure, RPM, and mounting space. Begapunk can help choose a standard model or custom passage layout.
Yes, if the passage layout is planned correctly. Each independent air function should have its own channel.
Yes. Begapunk has pneumatic-electric options, and custom designs can be reviewed when signal count and air passage count are known.
