Abstract
An arc-shaped segment (1) for assembling a segmented bearing cage. An arc length L and a radian angle θ of the arc-shaped segment (1) satisfy the following relationship: 360L/πD−20°≤θ≤360L/πD+30° with D being a diameter of the segmented bearing cage. The arc length L refers to an arc length corresponding to the radian angle θ of the arc-shaped segment (1). A segmented bearing cage comprising a plurality of arc-shaped segments (1). A bearing comprising the segmented bearing cage. After being assembled in the bearing, a plurality of arc-shaped segments abut on or connect with each other, to form a complete cage.
