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 lubricating element for rolling element tracks, particularly linear motion systems, has a body composed of a lubricant-storing material, which includes an application section capable of being brought in contact with a rolling element bearing surface to supply lubricant; the body has an elongated shape in a first storage region adjacent to the application section, and a lubricant flow through the first storage region triggered via the dispensing of lubricant at the application section is essentially oriented in the longitudinal direction of the first storage region.

Lubricating element and lubricating unit

A linear guide device has a guide rail, a guide car reciprocatingly movable on the guide rail in a longitudinal direction, a roll body revolving unit in which an endless row of roll bodies revolve, the roll body revolving unit having a load supporting portion which the roll bodies come in the load supporting engagement with a guide path of the guide rail and also with a running path of the guide car, the running path of the guide car being formed on a running path element which is connected with the guide car and which at least on a roll body entry-side end has a free supporting portion which is not supported on the guide car, the free supporting portion having a length which is at least equal to a diameter of the roll bodies.

Linear guide device

A rolling element chain ( ) comprises a plurality of rolling elements ( ) arranged in close succession and a longitudinal supporting band ( ). The supporting band ( ) in turn comprises a plurality of recesses ( ) for the accommodation of the rolling elements ( ), a plurality of retaining elements ( ) for retaining the rolling elements accommodated in the recesses ( ), where each rolling element ( ) is assigned at least one retaining element ( ), and at least one longitudinal flexible element ( ) for interconnection of the retaining elements ( ). Each rolling element ( ) is retained, by the at least one retaining element ( ) assigned to it, in the longitudinal direction (L) of the supporting band ( ) either at its leading side only or at its following side only.

Rolling element chain

A chain of rolling elements comprises a plurality of rolling elements and an elongate carrier belt with a plurality of recesses for receiving the rolling elements, a plurality of retainers for retaining the rolling elements received in the recesses and at least one elongate flexible element for connecting the retainers. The carrier belt comprises two lateral edge portions and a central portion connecting them, the retainers being connected to the at least one flexible element in the lateral edge regions of the carrier belt. Separate retainers are associated with successive rolling elements, at least one retainer associated with each rolling element being provided on the at least one flexible element in the longitudinal direction thereof before and after each rolling element.

Linear guiding apparatus for guiding an object

According to one example of embodiment of the invention, a bearing block 16 for a linear guide is constructed with two mutually perpendicularly crossing bending webs 28 and 34, formed by crossed double slits.

In a screw drive, in particular a ball screw drive, a double nut, formed of a pair of individual nuts, is tightened on a threaded spindle and the individual nuts are secured together against relative rotation by a locking member. The locking member is secured within a radially extending recess formed in and bridging the individual nuts. The locking member can be inserted with a certain amount of play into the recess or borehole and then secured within the recess by a cement or similar material so that it cannot be displaced. Various types of locking members can be used, such as locking bolts or threaded bolts. When the locking member is connected into the recess or ball it prevents any rotation of the individual nuts relative to one another.

Double nut and method of forming the double nut

A bearing assembly operatively interposed between a shaft and a housing having said shaft axially movably mounted therein for torque transmission therebetween includes a ball bushing inserted into a bushing receiving bore in the housing and guided through ball rings in ball races, with at least one of said ball rings being a load-transmitting ring including a load-transmitting ball ring section which rests radially inwardly against the shaft and radially outwardly against an external support surface defined by the ball bushing. The load bearing ball ring section of the at least one ball ring engages a race groove in the shaft on the shaft side of the ball ring and it engages a race groove of a bearing plate mounted in the ball bushing on the ball bushing side of the ball ring in a manner to transmit torque therebetween. The bearing plate may be pressed radially inwardly by means of a clamping device which presses against the ball bushing through contact surfaces which are oriented to intersect resultant planes generated by torque transmitting forces transmitted through the torque transmitting ball ring which are parallel to the bushing axis at an angle to insure a self-locking action.
