Abstract: A centrifugal mass assembly for a clutch includes a central axis, an arc-shaped centrifugal mass with a pair of radially offset apertures, and a guidance plate with a first annular ring. The first annular ring includes a pair of radially offset protrusions disposed in respective ones of the pair of radially offset apertures, or the first annular ring includes a radially extending slot and the arc-shaped centrifugal mass has a pair of pins fixed in respective ones of the pair of radially offset apertures and disposed in the radially extending slot. In an example embodiment, the first annular ring has a raised portion and the pair of radially offset protrusions or the radially extending slot is disposed on the raised portion.

Abstract: A torsional vibration damper, including: a hub supported for rotation around an axis of rotation; a first damper stage including a first damper flange non-rotatably connected to the hub and a first spring engaged with the first damper flange; a second damper stage including a second damper flange and a second spring, radially off-set from the first spring, and engaged with the second damper flange; and a friction control plate non-rotatably connected to the hub, free of contact with the first spring and free of contact with the second spring, and directly engaged with the second damper stage.

Abstract: A bearing includes an annular cup having an outer race and a radially extending flap. The flap defines an inner circumferential surface and a notch extending outwardly from the inner circumferential surface. The notch includes opposing radially extending sides, an outer circumferential wall, and a locking lip raised from the outer wall. Rolling elements are seated on the outer race and arranged to ride on a shaft. A sealing disc has an outer circumferential surface disposed against the inner circumferential surface and a tab received in the notch with the locking lip extending radially over the tab to secure the scaling disc to the cup.
