Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a Moog 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.
Compact capsule slip rings that carry mixed power and signal in a small footprint, with gold-to-gold contacts for low noise and low torque. AR is the larger body, BR mid-size and CR the miniature range.
| Published maximum | SRA-73574 / SRA-73587 | AR/BR/CR Series Capsule Slip Rings |
|---|---|---|
| Circuits | 36 | 76 meets or exceeds |
| Current per circuit | 10 A | 15 A meets or exceeds |
| Speed | 250 rpm | 300 rpm meets or exceeds |
| Voltage | 240 V | 240 V 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.
