Strut bearing integration

A suspension strut bearing comprising:

• a top mount including a stamped steel plate configured to mount to a vehicle frame, the stamped steel plate having a lower surface formed with a shape defining a first raceway;
• a guidance ring configured to oscillate relative to the top mount about an axis;
• a second raceway coupled to the guidance ring;
• a plurality of rolling elements contacting the first raceway and the second raceway such that the top mount directly contacts the rolling elements;
• and
• an internal seal located radially inwardly of the rolling elements and an external seal located radially outwardly of the rolling elements, wherein the internal and external seals are configured to fluidly isolate the rolling elements from a remainder of the suspension, wherein the external seal is overmolded onto the top mount and extends entirely through the top mount.

A suspension strut bearing comprising:

• a top mount configured to mount to a vehicle frame;
• a guidance ring configured to oscillate relative to the top mount about an axis;
• a lower raceway disposed on an upper side of the guidance ring;
• a plurality of rolling elements between the top mount and the lower raceway configured to enable relative oscillation between the top mount and the guidance ring;
• an internal seal located radially inwardly of the rolling elements;
• and
• an external seal located radially outwardly of the rolling elements;
• wherein at least one of the internal seal and the external seal are overmolded to the top mount, and wherein the external seal is overmolded onto the top mount and extends entirely through the top mount.
