A self-adjusting instrumented rolling bearing providing an outer ring and an inner ring delimiting a rolling chamber and at least one row of rolling elements disposed therein, and a detection device including a target integral with the outer ring and a sensor integral with the inner ring, configured to detect a relative rotation between the outer ring and the inner ring around a central axis. The outer ring has an inner surface in the form of a spherical portion centered about a tilting center of the bearing and forming a rolling surface for the rolling elements. The radius of the inner surface of the outer ring is greater than a distance defined between the tilting center of the bearing and a specific position of the sensor that is the farthest from the tilting center.

The present disclosure relates to a swing bearing and a wearable device. The swing bearing includes an inner ring, an outer ring, and a plurality of rolling elements, a plurality of first grooves arranged at intervals along a circumferential direction being formed on an outer circumferential surface of the inner ring, a plurality of second grooves arranged at intervals along a circumferential direction being formed on an inner circumferential surface of the outer ring, each rolling element being disposed between the corresponding first groove and the second groove, and the rolling element, the first groove, and the second groove being configured to restrict relative rotational movement between the inner ring and the outer ring and allow the inner ring and the outer ring to produce shaft axis deflection movement.

The present disclosure regards a spherical roller bearing having, an outer ring providing at least one inner raceway, an inner ring providing a first and a second outer raceway, a plurality of roller elements arranged in a first and second roller row disposed between the at least one inner raceway and the respective first and second outer raceway, the roller elements further providing axially inner ends. Moreover, the bearing includes a cage for one of guiding and retaining the roller elements in the first and second roller row, the cage including a plurality of cage pockets, wherein one of the roller elements is disposed within each cage pocket, and wherein the cage is roller centered by the axially inner ends.

A bearing (8) comprising a first row of rolling elements (10, 10a, 10b, 12, 12a, 12b) having a first pressure center (14) and a first contact angle, and a second row of rolling elements (10, 10a, 10b, 12, 12a, 12b) having a second pressure center (14) and a second contact angle, whereby said first pressure center (14) is arranged to coincide with said second pressure center (14) and whereby said first contact angle is the same as said second contact angle.

A hub-bearing unit is provided with: a rotatable hub, with an axially outer flange portion configured for engagement with a rotatable element of a motor vehicle, a bearing unit provided with a fixed radially outer ring, configured for engagement with a fixed element of the motor vehicle, a first, axially outer, crown of rolling bodies, and a second, axially inner, crown of rolling bodies, interposed between the radially outer ring and the hub. The hub also assumes the function of the radially inner ring of the bearing unit and the bell of a constant velocity joint. The hub-bearing unit is designed so that the axial distance between the center of the axially inner crown of rolling bodies and the rolling center of the constant velocity joint lies within a predetermined range according to the following formula:

[00001]$\{\begin{array}{cc}\mathrm{with}.Math..Math.L\ge 0,& 0.4\le \frac{P_B}{S+A+L}\le 4\\ \mathrm{with}.Math..Math.L<0,& 0.5\le \frac{P_B}{S+A}\le 4.Math.\end{array}\hspace{1em}$

A self adjusting instrumented rolling bearing having an outer ring and an inner ring delimiting a rolling chamber and at least one row of rolling elements disposed therein, and a detection device including a sensor integral with the outer ring and a target integral with the inner ring, configured to detect a relative rotation between the outer ring and the inner ring around a central axis. The outer ring has an inner surface in the form of a spherical portion centered about a tilting center of the bearing and forming a rolling surface for the rolling elements. The radius of the inner surface of the outer ring is greater than a distance defined between the tilting center of the bearing and a specific position of the target that is the farthest from the tilting center.
