Abstract
A linear guide assembly has a bar device, multiple partitions, multiple containing spaces and multiple rolling balls. The partitions are mounted between two bars of the bar device at intervals to form the containing spaces. The rolling balls are respectively and rotatably mounted in the containing spaces. Each partition has multiple first protrusions and multiple second protrusions. Each rolling ball is in point-contact with the first protrusions and the second protrusions of adjacent two of the partitions. With the point-contact configuration, an outer surface of each rolling ball is lubricated by much oil.
