Bearing arrangement for an electric motor or generator

A bearing arrangement for mounting a wheel and an electric motor or generator having a stator and a rotor to a vehicle, the bearing arrangement comprising a sealing element and a bearing block, wherein the bearing block includes a first coupling element for coupling to a first radial wall of the rotor and the wheel, and a second coupling element for coupling to the vehicle, with a bearing mounted between the first coupling element and the second coupling element to allow the first coupling element and the second coupling element to rotate relative to each other, wherein the first coupling element includes a mounting flange having a bolt hole arranged to extend through the mounting flange for receiving a bolt at a first aperture of the bolt hole for coupling the rotor and the wheel to the first coupling element, wherein the sealing element is arranged to be mounted over a second aperture of the bolt hole for inhibiting the ingress of material through the bolt hole into the electric motor or generator, wherein the mounting flange includes a plurality of bolt holes arranged to extend through the mounting flange for receiving a respective bolt at a first aperture of each of the bolt holes for coupling the rotor and the wheel to the first coupling element, wherein a plurality of sealing elements are arranged to be mounted over a second aperture of the respective bolt holes for inhibiting the ingress of material through the bolt hole into the electric motor or generator, wherein the plurality of sealing elements are coupled together.
