A process is provided which includes the steps of providing a rigid strip of material, forming 'projections along a side of the rigid strip, and shaping the rigid strip with a mandrel to form a shaped piece. The process also includes shaping the projections (403) to form a substantially closed end of the shaped piece. Also provided herein is a bearing assembly that includes a composite material comprising a metal substrate having a substantially cylindrical shape and a polymer layer overlying the metal substrate and disposed on an inner surface of the cylindrical shape. The bearing assembly also includes a closed end including a plurality of folded projections to form a closed end. |
