12. Втулка по п.11, у которой дополнительный фторполимерный слой содержит сигнальный наполнитель для сигнализирования о том, что втулка требует замены.
13. Втулка, содержащая:
несущий нагрузку субстрат, содержащий первую основную поверхность; и
литую фторполимерную пленку, наслоенную на первую основную поверхность несущего нагрузку субстрата, причем литая фторполимерная пленка содержит уменьшающий трение слой и клеевой слой, при этом несущий нагрузку субстрат проходит ближе к клеевому слою, чем к уменьшающему трение слою; и
покровный слой, перекрывающий литую фторполимерную пленку.
14. Втулка по п.13, у которой покровный слой содержит смазывающее вещество.
15. Втулка по п.14, у которой смазывающее вещество выбрано из масла, воска, жира, политетрафторэтилена, графита, наноалмазов, детонационных наноалмазов, дисульфида молибдена, частиц углерода, минералов или любого их сочетания.
