Product Description
The 50mm unobstructed through-bore provides routing space for hydraulics, pneumatics or for a concentric shaft mount. The BTH50120 uses our fiber brush technology which offers several advantages over conventional slip ring contacts including multiple points of contact per brush bundle, low contact force per fiber and low contact wear rates. In addition, fiber brushes do not require lubrication and produce virtually no wear debris. The BTH50120 features field serviceable brush blocks.
