A link rod for a motor vehicle, with a connecting rod (4) designed with an open profile that extends in an axial direction (x), which comprises a back (8) and two opposed sidepieces (9, 10) which are connected to one another by the back (8), extending away from the back so as to enclose an angle (a) of less than 180 between them. Two joints (2, 3) are connected to one another by the connecting rod (4), each joint comprises a joint housing (5) and an inner joint component (6) that is fitted and able to move in the housing and extends outwardly therefrom. The connecting rod (4) is embedded, at its respective axial ends, in one of the joint housings (5), and the sidepieces (9, 10) enclose an angle () of at least 90 between them.

One aspect relates to a rolling element for a ball bearing wherein the rolling element has: (i) a Young modulus E in the range up to and including 100 GPa; and (ii) a yield strength Rp.sub.0.2 in the range up to and including 1800 MPa, or wherein the rolling element has at least an alloy of nickel (Ni) and titanium (Ti), wherein the weight ratio of Ni:Ti in the alloy is in the range of from 57:43 to 50:50. One aspect is a rolling bearing with: a. at least an outer ring; b. at least an inner ring, wherein a raceway is defined by the arrangement of the outer ring and the inner ring; and c. at least three rolling elements wherein the rolling elements are arranged in the raceway, wherein at least one rolling element comprises at least an alloy as mentioned above.

A device with a rotating element includes a housing body formed from a light alloy, wherein the housing body has a housing body thermal expansion coefficient, a bearing liner formed from a liner material disposed within the housing body, wherein the bearing liner has a bearing liner thermal expansion coefficient, and a bearing to support the rotating element with an outer race, wherein the bearing has a bearing thermal expansion coefficient, the outer race is press fit within the bearing liner, and the bearing liner thermal expansion coefficient is lower than the bearing thermal expansion coefficient.
