A bearing cage segment for a rolling-element bearing includes at least one sliding surface on which a surface of at least one rolling element of the rolling-element bearing is rotatable, a first support element, such as an axial projection on an axial side of the cage segment having a radially open radially facing channel, at a first radial position for supporting a first band section of a band clamp during an assembling of the rolling-element bearing, and at least one second support element at a second radial position different from the first radial position for supporting a second band section of the band clamp.
