Abstract
A plastic bearing material of a bearing may include a block copolymer. The block copolymer may include structural blocks of two or more different polymers. A first polymer may include at least one of polyamide-imide and polybenzimidazole. A second polymer may include at least one of polydimethylsiloxane, methyl vinyl ether and polyisobutene. A method for manufacturing a plastic bearing material may include synthesizing a structural block of a first polymer and a structural block of a second polymer to define a block copolymer via a condensation reaction.
