A mechanical horological bearing (1) intended to be arranged on a mechanical timepiece movement (10), the bearing (1) including, coaxial around a common rotation axis (D), at least one internal frame (4) and at least one external frame (5) forming a running track (20), as well as a plurality of wheels (12) sliding or rolling in the running track (20), during a relative movement between the internal frame (4) and the external frame (5) that guides them and wherein at least one of the internal frame (4) and external frame (5) is a dynamic frame, at least one structural part of the bearing (1) being produced from an elastic metal material with a high damping capacity, the damping factor of which is greater than 10%, preferably greater than 30%.
