Rolling element bearing cage section, rolling-element bearing cage, and rolling-element bearing

摘要

A rolling-element bearing cage section for a rolling-element bearing is configured to guide at least one rolling element between a first and a second rolling-element bearing ring of the rolling-element bearing. The rolling-element bearing cage section is configured to partially or completely receive the at least one rolling element prior to installation in the rolling-element bearing. The rolling-element bearing cage section includes a porous material adapted to absorb a lubricant and release the lubricant as a result of a centrifugal force acting on the lubricant during rotation of the rolling-element bearing cage section, thus allowing a liquid lubricant to be used in a rolling-element bearing without the need for complex seals.
