    摘要： A bearing comprising a plurality of rolling elements arranged between an inner raceway (12) and an outer raceway (22) of the bearing, whereby a rolling contact interface is defined between a first rolling contact surface (31) on at least one rolling element and a second rolling contact surface formed by one of the inner and outer raceways (12, 22). The first rolling contact surface has a first RMS roughness R
    q1 and has a first roughness pattern y
    i , expressed in terms of the Peklenik number y. The second rolling contact surface has a second RMS roughness R
    q2 and has a second roughness pattern y
    2 . To minimise micropitting in the bearing, the rolling contact interface has a surface topography in which: - the roughness pattern of the first and of the second rolling contact surfaces are oriented in the direction of rolling, whereby γ 1 ≥ 3.0 and Y
    2 ≥ 10.0; and - the first and of the second rolling contact surfaces have substantially equal roughness heights, whereby 0.8 q1 /R
    q2 ≤ 1.25

    摘要： An apparatus for detecting irregularities in a rotation of roller bodies in a roller bearing, the apparatus comprising a measurement module and a processor module. The measurement module is operable to provide a deformation signal indicative of a deformation of a surface region of a bearing ring of the roller bearing, wherein the deformation is due to the rotation of the roller bodies over the surface region. The processor module is operable to extract one or more signal quantities of interest from the deformation signal and operable to provide statistical information on the one or more extracted signal quantities of interest.

    摘要： The present invention provides a rolling bearing which can be large-sized, is excellent in its corrosion resistance, and is allowed to prevent mounting accuracy from deteriorating, a fixing force from decreasing, vibration from occurring at a portion of the rolling bearing to be fixed to a bearing box or the like, and can be used for a long term even in a highly corrosive environment. A rolling bearing (1) has an inner ring (2), an outer ring (3), androllingelements (4) as bearing members thereof. Of regions of the bearing members which are exposed to a corrosive environment, a film having a sacrificial anode action for a base material of the bearing members is formed in a region including at least a surface (c, d) of the rolling bearing (1) to be fixed. The film formed on the surface (c, d) thereof to be fixed is porous. The base material of the bearing members consists of an iron-based material. The film is a thermal sprayed film formed by using a material containing any of elements zinc, aluminum, and magnesium as a thermal spraying material.
