Abstract
An object of the present invention is to provide a sliding bearing having an excellent initial conformability and seizure resistance as well as desired durability and heat resistance required particularly for high speed engine. The present invention provides a sliding bearing having a resin coating layer comprising a thermosetting resin being soft and having a good elongation at high temperature and a solid lubricant formed on a bearing alloy layer.
Claims3
A sliding bearing comprising a resin coating layer formed on a bearing alloy layer, wherein that the resin coating layer comprises:
- a thermosetting resin being soft and having a good elongation at high temperature which exhibits a tensile strength of from 70 to 110 MPa and an elongation of from 7 to 20% at 25° C. and a tensile strength of not lower than 15 MPa and an elongation of not lower than 20% at 200° C. in an amount of from 70 to 30 vol-%;
- and
- a solid lubricant in an amount of from 30 to 70 vol-%, and
- wherein a bipartite total of the soft thermosetting resin and the solid lubricant becomes 100 vol-%, and a Vickers hardness Hv of the resin coating layer is not greater than 20.
