<p>A linear guide unit, with a guide carriage arranged on a guide rail, and rolling bodies which circulate in circulating channels. Each circulating channel has a load section, a return section and two deflection sections endlessly connecting the load section to the return section. The load section is delimited by running tracks for the rolling bodies, which are formed on the guide carriage and guide rail, and with lubricant channels which are formed on the guide carriage and are connected to the circulating channels. An end is connected to a transfer point to a further lubricant channel or the circulating channel. A seal with an annularly closed sealing section is provided between the end of the lubricant channel and the transfer point, and is designed as a valve which prevents the lubricant channel from running at no-load.</p> |
