Through Bore Slip Ring Through bore slip rings (also known as "through hole slip ring") are slip ring with through bore, this series are designed for being installed with flange on a sleeve bracket, also they totally meet with continuous transmission of power and/or signal under 360 degree unrestrained rotations. This kind of slipring use hollow shaft that applies the best advanced fiber brush technology and precious metal multi-contacting, low noise, low contact pressure and maintenance free. Barlin Times standard through bore size could be from 12.7mm- 190mm are optional, the standard circuits are 6 rings, 12 rings, 18 rings and 24 rings are available, the current can be alternative from 2A-800A. Standardized & modularized design, we could fully customize the best suitable product according to the special requirement of customer in different applications. If you have specific customized requirement, please feel free to consult us so that our sales engineer could recommend the most suitable product to you for you reference.
