Claim 0:
1. A centrifugal pendulum absorber, comprising:
a center plate arranged to receive a torque;
a first pendulum mass and a second pendulum mass each connected to the center plate, the first and second pendulum masses axially bracketing the center plate;
a resilient bumper disposed between the first and second pendulum masses and connected to the first and second pendulum masses, the resilient bumper including a core enclosed by a casing, wherein the core is a metal and the casing is a polymer; and
a fastener fixedly connecting the first pendulum mass to the second pendulum mass, wherein the resilient bumper is disposed around the fastener;
wherein the casing extends entirely about the fastener, and the core extends partially about the fastener;
wherein the core includes a first end and a second end circumferentially spaced from each other about the fastener and defining a gap therebetween, the gap being configured to cause a center of mass of the core to be radially offset relative to an axis of rotation of the casing.
