A moveable guide carriage forms a linear roller bearing on a guide rail. The guide carriage has four endlessly revolving rows of rollers that are guided in respective roller tracks. The guide carriage has a central main body with two end sides that are spaced apart from each other in the direction of movement. A respective end cap is arranged on the two end sides of the main body. The rows of rollers are deflected in the end caps. At least one of the end caps includes a lubricant input on an outer side. The guide carriage includes a branching lubricant line between the lubricant input and the four rows of rollers or the four roller tracks. At least two internal nonreturn valves are provided in the lubricant line in the interior of the end cap or between the end cap and the main body.

Guide carriage

A guide carriage for a linear roller bearing is supportable in a longitudinally displaceable manner via at least one row of rollers on a guide rail which extends in a longitudinal direction, a separate rolling surface part which includes a rolling surface for the rollers is assigned to each row of rollers, and the rolling surface part is connected via an adhesive layer to a carrier body. The adhesive layer is designed essentially planar on the back side of the rolling surface part which faces away from the rolling surface, the rolling surface part being accommodated in a recess&#x2014;which has an L-shaped cross section&#x2014;of the carrier body.

Linear roller bearing with separate rolling surface parts

A guide carriage for a linear roller bearing includes a main body, which may bear in a longitudinally movably manner and via at least a first and at least a second endlessly circulating roller row against a guide rail that extends in a longitudinal direction, a deflection assembly provided on an end face of the main body and including at least one curved inner deflection channel for the first roller row, and at least a second curved outer deflection channel for the second roller row, the inner deflection channel being located within the outer deflection channel, the deflection assembly includes an end cap, on the inner side of which&#x2014;that faces the main body&#x2014;an outer boundary surface of the outer deflection channel is provided, and at least one separate, one-pieced deflection piece inserted in the end cap, on which an inner boundary surface is provided that covers the entire outer deflection channel. An outer boundary surface is provided that covers the entire inner deflection channel on the deflection piece.

Linear roller bearing with deflection piece

A device () for feeding working fluid to an assembly () requiring working fluid includes at least one fluid channel (-) extending from a surface () and at least one screw element () capable of being screwed from the surface () into the at least one fluid channel (-) for feeding working fluid into the fluid channel (-) or for closing the fluid channel (-), the at least one fluid channel (-) having a first section () directly adjacent to the surface () with a larger width, a second section () with a smaller width and, between the first section () and the second section (), having a first transition region () with an annular surface (), and the screw element () having at least one sealing surface () capable of being brought into sealing engagement with the annular surface (). The fluid channel (-) is deformable in the second section () by a pressure applied by the screw element () to the annular surface () in the sense of reducing the volume of the fluid channel in the second section ().

Working fluid feeding device

A spacer for roller bodies, which are guided in a roller bearing and which have an axis of symmetry and have an axis of symmetry, defining a rolling axis, about which they roll in a revolution path of the roller bearing, includes two diametrically opposed, spaced-apart end parts, which are each located transversely to the direction of motion of the roller bodies and have contact faces for rolling faces of the roller bodies; two diametrically opposed, spaced-apart lateral parts, and each of the lateral parts connects the two end parts, has a platelike shape, with a flat side, extending transversely to the rolling axis of the roller bodies, for contact with the roller bodies, and short sides extending substantially in the direction of the rolling axis of the roller bodies, and is stiffened with regard to bending essentially orthogonally to the rolling axis of the roller bodies in such a way that in its motion along the revolution path, it essentially maintains its shape; and at least one rib, connecting the two lateral parts between the two end parts, which rib has contact faces for the rolling faces of two successive roller bodies.
