Abstract

A friction-reducing abrasion resistant bearing material is described. The material comprises a monolithic, porous polytetrafluoroethylene (ePTFE) having dispersed therein a wear-resistant thermosetting or thermoplastic resin material.

Claims

exact text as granted — not AI-modified
1 . A bearing article comprising: 
 a porous monolithic PTFE material, and    at least one polymer resin selected from the group consisting of thermosetting resins and thermoplastic resins distributed within the pores of the PTFE material.    
   
   
       2 . The bearing article of  claim 1 , wherein said at least one polymer resin comprises polyimide.  
   
   
       3 . A bearing article comprising: 
 a porous monolithic PTFE material, and    at least one wear resistant polymer resin distributed within the pores of the PTFE material.    
   
   
       4 . The bearing article of  claim 3 , wherein said at least one polymer resin comprises polyimide.
