  • Patent number: 9646737
    Abstract: The invention discloses a bearing ring. The bearing ring, with a body, has an electrically insulating coating made up of a ceramic layer with pores and a plastic for filling the pores and coating the ceramic layer. According to the invention, the pores have a proportion between 10 and 50% in the ceramic layer. The invention furthermore defines an electrically insulating coating, made up of a ceramic layer with pores and a plastic for filling the pores and coating the ceramic layer. The invention further still discloses a method for applying an electrically insulating coating to a body of a bearing ring.

  • Patent number: 8764301
    Abstract: An anti-friction bearing, which has an outer ring, an inner ring and rolling bodies that are arranged between the rings, distributed over a circumference of the rings, and roll on the rings. For an increase of thermal insulation, electrical insulation and the like, a film section, which is manufactured without the removal of material from a plastic film, is attached on an outer circumference of the outer ring over at least part of an axial width of the outer ring and at least over part of an outer circumference of the outer ring.

  • Publication number: 20130084033
    Abstract: An electrically insulating bearing ring, in particular of a roller bearing, including a base body (2) and an electrically insulating layer (3) which is secured to the base body (2). The problem of providing an electrically insulating bearing ring, in particular of a roller bearing, with only a small layer thickness of the electrically insulating layer, is achieved according to the invention in that the electrically insulating layer (3) includes a polyamide, that the electrically insulating layer (3) has a thickness of approximately 20 microns to approximately 200 microns and that the electrically insulating layer (3) is securely arranged on the base body (2) by an intermediate layer (9).

  • Publication number: 20120008890
    Abstract: A method for producing a bearing race which has electrical insulation for a rolling bearing, and a bearing race for a rolling bearing produced, for example, by the method. The method includes the steps of: providing a body of the bearing race, applying a multilayer insulating coating enclosing the body of the bearing race at least in segments by winding the body of the bearing race with a carrier material enclosed by a resin for forming the electrical insulation. The insulating layer has an additive improving the electrical properties, particularly the dielectric properties, and/or mechanical properties of the electrical insulation. A bearing race and a method for producing a bearing race are disclosed. The bearing race is particularly suitable for shield alternating currents.

  • Patent number: 6416228
    Abstract: A rolling-contact bearing for a shaft journal wherein the outside diameter of the shaft journal is thermally insulated relative to the shaft through which a heat transfer medium flows. The bore of the inner race on the shaft journal is provided with a ceramic layer predominantly of zirconium oxide and a smaller among of yttrium oxide to reduce the heat transfer from the shaft journal to the rolling-contact bearing. The inner race also has lateral surfaces toward the elements securing the bearing on the shaft journal. Those lateral surfaces may be provided with a ceramic layer as well.
