Beschreibung
Zusammenfassung:	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 Rp0.2 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.
