The invention relates to a guide body of a linear movement guide, which is provided for arranging and executing longitudinal movements on a rail (1). Such guide bodies (2) are provided with at least one roller body circulation (6a - 6d), each roller body circulation having a return channel, a support zone (11) and two deflection channels (13) connecting the return channel (12) and the support zone (11), and Several rolling elements (7) are contained in each rolling element revolution, guide means being provided for guiding the rolling elements in the rolling element revolution. With such a guide body, a possibility is to be created to be able to dispense with the supply of lubricant. To this end, the invention proposes that at least some of the guide means have a plastic with at least two components, at least in the area of running surfaces for the rolling elements, the first component is embedded in the form of particles in the second component, the first component compared to a metallic or ceramic one Friction partner has a lower coefficient of friction than the second component, and the respective guide means are generated at least in the area of the treads by injection molding the plastic. |
