Abstract
An anti-friction insulated bearing system, including a bracket disposed about a motor driveshaft and a bearing disposed within the bracket configured to support the driveshaft for rotation. The system also includes an outer bearing cap disposed proximal a drive end of the bracket and an inner bearing cap. The system further includes an insulation sleeve disposed within the bracket proximal the bearing. The outer bearing cap, the inner bearing cap and the insulation sleeve are configured as modular components of the system. The modular insulation sleeve allows the use of standard anti-friction rolling element bearings. The modular components have common inner and outer bearing caps that can be used across a multitude of configurations with a minimal number of parts.
