Slip Rings with Through Bores

The unobstructed bore through the center provides routing space for hydraulics, pneumatics or for a concentric shaft mount. Our through-bore slip rings feature our fiber brush technology which offers several advantages over conventional slip ring technology including multiple points of contact force per fiber and low contact wear rates. In addition, fiber brushes do not require lubrication and produce virtually no wear debris.
