Abstract: A rolling-element bearing unit includes at least one inner ring, an outer ring, and first and second rolling-element rows between the at least one inner ring and the outer ring, the second rolling-element row being axially spaced from the first rolling-element row by a gap, and the bearing unit including at least one sensor unit in the gap.

Abstract: A bearing component of a rolling element bearing, such as a rolling element, a bearing ring, and/or a cage for retaining rolling elements of a rolling element bearing, has an outer surface with a plating layer providing at least 97 wt. % tin. The tin of the plating layer provides alpha and beta phases of tin in an alpha/beta phase ratio of less than 10%.

Abstract: A sensor module configured to detect a vibration of a mechanical component includes a base connectable to the mechanical component, at least one spacer extending from the base, and a circuit board connected to the base by the spacer such that a mechanical vibration is transmitted from the component to the base to the spacer to the circuit board. The circuit board includes a circuit and wirelessly transmits signals indicative of a detected vibration. The spacer includes a body portion and a pin portion projecting from an end of the body portion. The pin portion extends into the at least one hole, and the body portion is blocked from passing though the at least one hole by contact with a region of a first side of the circuit board surrounding the at least one hole.

Abstract: A module includes a first partial housing and a second partial housing, wherein the first partial housing and the second partial housing together form a recess, a circuit board disposed in the recess; and an encapsulation mass, which closes the recess. A material from which the first partial housing is manufactured and a material from which the second partial housing is manufactured have a difference in thermal expansion coefficients that is at most 10% of the largest value of the two thermal expansion coefficients, the first partial housing includes a sealing structure and the second partial housing includes a counter-sealing structure, and at least one of the sealing structure and the counter-sealing structure is configured to extend into the other of the sealing structure and the counter-sealing structure.

Abstract: A module for detecting a physical value of a gaseous medium includes a discrete component including a detection section on a surface, the discrete component being configured to detect the physical value of the gaseous medium that acts on the detection section, a supply-line component configured to introduce the gaseous medium to the detection section, a seal in contact with the supply-line component and the surface of the discrete component and configured to fluidly seal the detection section on the surface of the discrete component. The seal includes a seal lip configured to enclose the detection section such that the seal forms a sealing space, the sealing space including the detection section and being separated from an external space by the seal.

Abstract: A module for detecting a vibrational behavior of a mechanical component includes an attachment component configured to be rigidly mechanically connected to the mechanical component in order to absorb a mechanical vibration of the mechanical component, a circuit board including a circuit, the circuit board being configured to detect the mechanical vibration of the mechanical component and, based on the detected vibration, to wirelessly transmit a signal indicative of the vibrational behavior, and at least one spacer mechanically connecting the circuit board to the attachment component such that the mechanical vibration is transferable from the attachment component to the circuit board.
