Abstract
A novel linear guide plain bearing has a guide rail with rail-grooves formed respectively in opposite side surfaces thereof, and a slider with slider-ridges formed respectively on opposed inner side surfaces thereof. The slider is mounted in a straddling manner on the guide rail for sliding movement therealong. Each of the guide-grooves has a Gothic arch cross-sectional shape while each of the slider-ridges has a circular arch cross-sectional shape. The slider slides relative to the guide rail in an axial line contact condition. A solid lubricant-containing resin coating is formed on each of the slider-ridges, whereby the sliding resistance and sliding noise can be reduced more efficiently.
