Abstract
The invention relates to a carriage of a profile rail roller guide, comprising an external lubricant connection point () for the feeding of lubricant and comprising lubricant channels () for the lubricant, which are connected to rolling-element channels () in order to supply the rolling-element channels with lubricant, wherein a plurality of orders of lubricant channels () is provided, the orders being series-connected one downstream of the other in the flow direction of the lubricant, and wherein each lubricant channel () of a higher-ranking order is assigned a plurality of mutually parallel-connected lubricant channels () of a low-ranking order of lubricant channels (). The sum of the flow cross-sectional areas of said lubricant channels () of the low-ranking order is equal to the flow cross-sectional area of the connected lubricant channel () of the higher-ranking order.
