The disclosed bearing mount includes a bearing with inner and outer raceways and rollers operating between the raceways, the raceways being fixedly held fast relative to separated structures and the rollers rotatably supporting them and the structures relative to one another. The rollers of the bearing are formed of electrically and magnetically nonconductive material, specifically comprised of silicon nitride material. This bearing mount is effective for operation within a pulsed high energy electrical circuit or within the magnetic fields generated thereby, as in an inner roller electrode or an hour glass roll used in an electric-resistance can welder, inasmush as it isolates the structures electrically from one another via the bearing mount independently of other insulator devices, while operating without magnetic roller polarization and increased roller collisions.
