A multi-component snap assembly is disclosed herein in which a snap flange has a snap nose with a contact face including a relief. The relief is configured to prevent undesirably high stress in the snap flange during assembly with another component that includes a retention pocket. A method of attaching or connecting two components with each other using a snap flange with a relief is also disclosed herein.

A snap ring for guiding rolling elements between an inner ring and an outer ring of a bearing assembly includes an annular body having an axially facing side surface and a radially extending flange. The body is circular and has a circumferential gap between a first end of the body and a second end of the body and a recess in the side surface near the gap. The recess is configured such that a tool is introducible into the recess from outside the bearing assembly in order to remove the snap ring from the bearing assembly.

The dental handpiece consists of a housing with a handle and a turbine that can be operated with compressed gas or compressed air. The rotational movement of the turbine driven by compressed gas is transmitted to the dental tool via a rotor shaft and a chuck. The rotor shaft is rotatably supported by at least one axial groove ball bearing. The radial rigidity required for operating a dental handpiece is achieved by axially preloading the ball bearings. Projections on the housing and the shaft disc of the at least one axial groove ball bearing allow the axial groove ball bearing to be used as radial groove ball bearings. The proposed design of the dental handpiece exhibits little power loss or frictional loss in comparison to dental handpieces with radial groove ball bearings, and slip and drilling friction components can be virtually completely prevented in particular.

A split bearing protector with a flexible design that adds improved moisture protection to a bearing and can be installed without removing the bearing from the machine in which it is installed.

A wave spring having an axially resilient spring section including at least one one-layer wave-shaped spring configured to provide a spring force in an axial direction of the wave spring, and a radially resilient spring section configured to provide a spring force in a radial direction. The wave spring may be made from a continuous flat wire that forms both the axially resilient spring section and the radially resilient spring section, the flat wire being rotated 90° at a transition from the axial spring section to the radial spring section.

One embodiment of the present invention provides a ball bearing roller assembly comprising an inner ring having an insertion hole into which a protrusion of a storage body is inserted; an outer ring having a hollow through which the inner ring is inserted, and provided outside the inner ring, at least one ball bearing provide between the inner ring and the outer ring, and in rolling contact with the inner ring and the outer ring; a cover inserted and coupled to a space between the inner ring and the outer ring, and fixing the ball bearing to the outer circumferential surface of the inner ring and the inner circumferential surface of the outer ring and a detachable coupling portion formed to extend from one end portion of the inner ring, and having an insertion space portion into which a vertical wire of the storage body is inserted.

A temperature-robust polymer shroud for a roller bearing seal includes a shroud body and an inner diameter leg defining respective portions of a single continuous part. The shroud body encircles a rotation axis of the polymer shroud and extends predominantly in directions orthogonal to the rotation axis from an inner diameter to an outer diameter. The inner diameter leg connects to the shroud body at the inner diameter and encircles the rotation axis, wherein, along the entire inner diameter of the shroud body, the inner diameter leg is oriented at an oblique angle to the rotation axis to extend both (a) radially inward from the inner diameter and (b) axially away from the inner diameter along a first direction parallel to the rotation axis. A roller bearing seal includes a seal case, an elastomer lip, and the temperature-robust polymer shroud.

The invention relates to a rolling bearing with two bearing rings and rolling elements running between same, and a sensor for detecting movements and/or positions of the bearing rings relative to one another, wherein the sensor is fastened to one of the bearing rings and is directed towards a measurement surface on the other bearing ring, wherein said measurement surface comprises a contour projection projecting towards the sensor and/or a contour recess open towards the sensor in the form of a groove or blind hole, which projection or groove influences the measurement signal of the sensor and the movement of which relative to the sensor transverse to the main signal direction of the sensor modifies the measurement signal of the sensor.
