Roller bearings, and struts and gas turbine engines involving such bearings

摘要

A roller bearing (114) for a gas turbine engine includes: a roller (140) having a rolling surface (142) and an end (144); a race (120) having a flange (122) and defining a raceway (126), the raceway (126) terminating at the flange (122), the raceway (126) being operative to receive the roller (140) such that the rolling surface (142) of the roller (140) engages in rolling contact with the raceway (126); and a hard coating applied to the flange (122) such that the end (144) of the roller (140) engages in sliding contact with the coating.
