Linear guide for roller bearings

A guide member for a linear-movement guide, which is arranged on a rail so as to execute movements in longitudinal direction, said guide member having at least one roll body circuit, wherein each roll body circuit comprises a return channel, a bearing zone, as well as two deflection channels that connect the return channel and the bearing zone, each roll body circuit further comprising several roll bodies, wherein the guide member is provided with guide means for guiding the roll bodies in the roll body circuit, said guide means having running surfaces, characterized in that at least some of the guide means comprise a plastic material with at least two components in a region of the running surfaces of the guide means for the roll bodies (7), of which the first component is incorporated into the second component in the form of particles, the first component has a friction coefficient lower than a friction coefficient of the second component, relative to a metal or ceramic friction partner, and the respective guide means are produced by spraying on plastic with an injection-molding technique, at least in the region of the running surfaces.

A roll body circuit for a linear movement guide that is provided with roll bodies for the circulation, said roll body circuit comprising a return channel, a bearing zone, as well as two deflection channels that connect the return channel and the bearing zone and having guide means for guiding the roll bodies, said guide means having running surfaces, characterized in that at least some of the guide means are provided at least in a region of the running surfaces for the roll bodies with a heterogeneous plastic, having at least two components, and that the first component is embedded in the second component in the form of particles and the first component has a lower friction coefficient than the second component, relative to a metal or ceramic friction partner.
