A method for conducting structural fatigue life testing of a bearing, in which a cam embedded in the bearing under test generates a rotational dynamic radial expansion and transmits the expansion through the bearing to a load collar compactly mounted on the periphery of the bearing, forcing the load collar to deform synchronously with the expansion, thereby applying, together with the cam, a rotational dynamic strain pressure load, mainly in the radial direction in both inward and outward directions, to the bearing, based on the elasticity of the load collar itself, as a test load for the structural fatigue life testing of the bearing. Based on the above method, the present invention also provides a holding mechanism that provides a rotation-resistant support for the load collar and a bearing rotation test rig capable of assembling the holding mechanism.

A bearing seal for a rolling bearing with standard boundary dimensions that comprises a first flinger fitted into a first bearing ring and a second flinger fitted into a second bearing ring. Each flinger further comprises a correspondingly numbered sealing body. A first sealing body engages the second flinger and/or the second bearing ring, and a second sealing body engages the first flinger and/or the first bearing ring. The axial width of the bearing seal varies along the radial direction of the bearing. Starting at the first bearing ring, with a narrow width W, defined relative to the total radial size of the bearing seal L, wherein the ratio W/L is less than or equal to 0.5, the bearing seal widens toward the second bearing ring, thereby providing extra space between the rolling elements and/or cage and the bearing seal adjacent to the first bearing ring.
