A rotor blade for a rotor assembly is provided which includes a root, an airfoil, a platform, and a damper. The airfoil includes at least one cavity. The platform extends laterally outward from the blade between the root and the airfoil, and includes an airfoil side, a root side, and an aperture extending between the root side of the platform and the cavity within the airfoil. The damper, which includes at least one bearing surface, is received within the aperture and the cavity. The bearing surface is in contact with a surface within the cavity and friction between the bearing surface and the surface within the cavity damps vibration of the blade.
