 LPK038-0810 Pancake Slip Ring Slip Ring with Through Bore 38.1mm

A slip ring can be used in any electromechanical system that requires unrestrained, continuous rotation while transferring power or data from a stationary to a rotating structure.
The 38.10mm unobstructed through-bore provides routing space for hydraulics, pneumatics or a concentric shaft mount. The LPK038 Pan Cake Slip Ring uses advanced 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 LPTK038 features field serviceable brush blocks.
