Why we named it as slip ring with through bore? We usually call it in this way because it has a bore in the middle part. It has very wide applications, mainly installed in the equipments with a rotation axis, and the rotating joint needed to transmit signals in the fixed and unfixed structures. In the near future, this type of through bore slip rings would widely used in the new areas including automation equipment, automated testing equipment and automated robots. At that time, there would have high requirements on their structures and technical parameters, so MOFLON not only manufactures the existing products but also invests lot of funds to research new products so that the new structure can meet the demand of slip rings in the future.
