The invention relates to a bearing assembly (10) comprising at least one first bearing element (12) and a second bearing element (14) which are rotatably connected relative to each other along a common longitudinal axis (14). The bearing assembly (10) comprises a brake device (18) which inhibits the rotation of the two bearing elements (12) relative to each other by means of a frictional force produced by the brake device (18), wherein the brake device (18) has at least one frictional element (20) and at least one clamping device (22), by means of which the frictional element (20) is permanently clamped against one of the two bearing elements (12). The bearing assembly also comprises a coupling device (30) which can be moved between an open state and a closed state. In the closed state, the brake device (18) is engaged, whereby when the two bearing elements (12) rotate relative to each other, the rotation is inhibited by the frictional force produced by the brake device (18), and in the open state, the brake device (18) is disengaged.

The invention relates to a rotationally symmetrical hollow body having a main body (18), and to a method for producing the same, having a cavity (12) which extends along a longitudinal axis (14) of the main body and which is delimited by an inner wall (17) of the main body, wherein at least one filling body (24) is inserted into the cavity, the longitudinal extent of which filling body in an axial direction with respect to the longitudinal axis of the main body is smaller than the length of the main body, and wherein the filling body is fixed in a fixing position relative to the main body by at least one clamping means which acts between the filling body and the main body, and a functional region (21) is formed in the main body by the filling body.

A bearing system for a rotating vertical shaft includes a first ball bearing, having a first pitch diameter and a first axial stiffness and a second ball bearing having a second pitch diameter and a second axial stiffness. The first ball bearing is a deep groove Conrad bearing. The second ball bearing is an angular contact bearing. The first and second ball bearings are coaxial, secured to one another and rotatable together. The first pitch diameter is at least 1.5 times greater than the second pitch diameter. The bearing system has an axial stiffness ratio defined by the first axial stiffness divided by the second axial stiffness. The axial stiffness ratio is based on an axial preload force applied to the second outer ring such that an operating torque of the bearing system is within a predetermined range at temperatures from minus 40 to positive 85 degrees Celsius.

The invention provides a fixed rolling element bearing assembly comprising: a housing; an inner race for attaching to a rotating shaft; a cage and rolling element assembly positioned around the inner race; first and second positional locators for positioning the cage and rolling element assembly between inner edges thereof; a thrustwasher adjacent an outer edge of either of the first or second positional locator and fixably connected to the housing.

A slide-stop device designed and adapted for wedge engagement with opposing internal sur-faces of a linear motion slide track having an essentially C-shaped cross-sectional profile. The slide-stop device includes two lateral engagement sections extending essentially parallel to the longitudinal direction on opposite sides of the slide-stop device and having engagement surfaces facing outwardly in opposite transverse directions of the slide-stop device, two flex-ion elements being arranged on opposite sides with respect to the longitudinal direction of the slide-stop device. Each of the two flexion elements have one or more strips extending between and connecting the end regions of the lateral engagement sections, each strip being curved or bent to point outwardly with respect to the longitudinal direction of the slide-stop device. At least the strips of the flexion elements are made of elastic material.
