Abstract
A bearing structure with a low coefficient of friction and a distinguished wear resistance is obtained by coating a shaft with a resin composition comprising PAI and 5 to 50% by weight of PTFE, based on total resin composition and/or coating a bearing with a resin composition comprising PEEK and not more than 50% by weight of PTFE, based on total resin composition. By adding potassium titanate whiskers or a lead compound to the bearing resin composition, more improved coefficient of friction and wear resistance are obtained.
