    摘要： A polymeric thrust bearing is provided for an ultra-high PV environment. The polymeric thrust bearing includes an annular bearing body having an inner perimeter and an outer perimeter, and a plurality of lubricant channels extending across the annular bearing body from the inner perimeter to the outer perimeter. The annular bearing body comprises a polymer composition comprising a polymer having typically a glass transition temperature of at least about 140° C., such as an aromatic polyimide or a poly(aryl ether ketone), and at least one friction and wear additive. The polymeric thrust bearing is configured to withstand a velocity and a pressure in a lubricated environment in which the product of the velocity and the pressure is about 1,100,000 psi-fpm (23540 kg/cm2×m/min) or more.

    摘要翻译： 为超高PV环境提供聚合推力轴承。 聚合推力轴承包括具有内周边和外周边的环形轴承体，以及从内周向外周延伸穿过环形轴承体的多个润滑剂通道。 环形轴承体包括聚合物组合物，其包含通常具有至少约140℃的玻璃化转变温度的聚合物，例如芳族聚酰亚胺或聚（芳基醚酮），以及至少一种摩擦和耐磨添加剂。 聚合推力轴承被配置为承受速度和压力的乘积约为1,100,000psi-fpm（23540kg / cm2×m / min）或更高的润滑环境中的速度和压力。
