An apparatus comprising a plurality of sliding members, at least one of the sliding members being a self-lubricating-function sliding member characterized by containing a precursor compound which produces a solid-lubricating compound during sliding by reacting with an atmosphere in which the sliding member is used or a component of a material with which the sliding member is in sliding contact.

Apparatus having sliding member with precursor material providing solid

A sliding bearing to be immersed in molten metal has low friction and long life. The bearing is provided with a solid particle trap portion for preventing solid particles in the molten metal from penetrating between sliding surfaces of the shaft and the bearing and removing the solid particles. Abrasive wear and an increase in friction, caused by biting of the solid particles into the sliding surfaces can be prevented. A continuous hot-dip plating apparatus employs the sliding bearing in the molten metal.
