(57) [Summary] In a general linear guide device, a rolling element and a guide rail or a slider main body easily cause metal contact even under grease lubrication, and wear accompanying the operation progresses, resulting in good operation for a long time. Sex cannot be maintained. A lubricant-containing polymer member (8) is slidably contacted with a guide rail (1) outside an end cap (2B) of a slider (2). No. 1 was provided, and a compound-reactive-film-forming compound was added thereto together with a lubricant. The rolling element was subjected to a surface treatment, and a compound reaction film made of an acidic phosphate ester or the like was previously formed on the surface of the rolling element. The lubricant and the compound-reactive-film-forming compound that ooze out over time from the lubricant-containing polymer member 81 are supplied to the rolling elements, and the lubrication and the repair of the compound-reactive film on the surface thereof are automatically performed, so that long-term good operation is achieved. Sex is maintained. |
