Abstract
A ball thrust bearing comprises a pair of stamped sheet metal races and a full complement of bearing balls. One race has bonded elastomeric sealing lips which cooperate with the other race to seal the inner and outer diameter sides of the bearing respectively. The sealing lip for the inner diameter side of the bearing retains the bearing components in a unitized assembly and is also designed to permit snap assembly of the races. The races and sealing lips are shaped to provide effective sealing, effective retention and ease of assembly.
