A rolling-element bearing includes a first ring having two raceways and at least one second ring having two raceways and rolling elements between the rings, and a ring raceway width is defined as an axial distance between the axially outer ends of the first ring raceways. A radially extending integral mounting flange extends from the first ring at a location between first and second sides of the first ring, and the flange has an axial abutment surface. A first shoulder extends from the first side toward the axial abutment surface. The first axial abutment surface is located an axial distance from the first side of the first ring, the axial distance being 10% to 50% of the ring raceway width, and a ratio of an outer diameter of the mounting flange to the width of the first ring raceways is from 5 to 25.

The invention relates to a tower part for a wind turbine including at least one wall segment and at least one aperture segment including at least one aperture. The wall segment and the aperture segment are connected and the aperture segment is of a substantially uniform thickness and is thicker than the thickness of the wall segment. The invention further related to an aperture cover system for covering at least one aperture in a tower part for a wind turbine including cover plates and attachments for attaching the system to the tower part, wherein the attachments do not affect the fatigue limit of the tower part. Finally, the invention relates to a method for manufacturing a wind turbine tower part and uses thereof.

This invention relates to a tower for a wind turbine, comprising one or more tubular tower sections, having an outer jacket wall and an inward directed flange in its lower and upper ends, and at least one platform arranged inside the tower for facilitating access for maintenance and repairs to the inner of the tower and to the nacelle. The tower also comprises a support structure including at least three elongated tensile load carrying members, which each is attached in its upper end to the upper flange of the tower section and in its lower end to the lower flange of the tower section and which supports one or more platforms that are suspended by the tensile load carrying members while at least one ladder is attached to the platforms. The at least one ladder is stabilized in the horizontal direction by transversal tensile load carrying members extending from the ladder to the tensile load carrying members that are vertically arranged between the upper and lower flanges. The invention also relates to a method for arranging a platform inside a tower.
