Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a Servotecnica part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These series from our supply network is the closest match on published figures.
Through-bore slip rings with a hollow centre so shafts, pipes or cables can pass through, carrying power, signal and fieldbus data. Standard bores run from 12.7 mm to 100 mm and custom bores are offered.
| Published maximum | SVTS C (C 01-C 11) | ER Series Through Bore Slip Ring |
|---|---|---|
| Circuits | 96 | 24 |
| Current per circuit | 20 A | 15 A |
| Speed | 500 rpm | 300 rpm |
| Voltage | 600 V | 380 V |
| Bore | 100 mm | 100 mm meets or exceeds |
Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
