Abstract

A lubricating grease composition for a polyamide resin member is used to be supplied as a lubricant on a surface of at least a sliding portion of the polyamide resin member including the sliding portion with an other member. The lubricating grease composition for a polyamide resin member contains a base oil which is a synthetic hydrocarbon oil, and a thickener which is at least one metal complex soap of a barium complex soap and a lithium complex soap, wherein a kinetic viscosity at 40° C. of the base oil ranges from 30 to 200 mm 2 /s and a drop point of the thickener is 270° C. or more.

Claims

exact text as granted — not AI-modified
1 . A lubricating grease composition for a polyamide resin member used to be supplied as a lubricant on a surface of at least a sliding portion of the polyamide resin member including the sliding portion with an other member, wherein the lubricating grease composition for a polyamide resin member comprises:
 a base oil which is a synthetic hydrocarbon oil; and   a thickener which is at least one metal complex soap of a barium complex soap and a lithium complex soap,   
       wherein a kinetic viscosity at 40° C. of the base oil ranges from 30 to 200 mm 2 /s, and
 a drop point of the thickener is 270° C. or more. 
 
     
     
         2 . The lubricating grease composition for a polyamide resin member according to  claim 1 , wherein the base oil is a single oil of a poly-α-olefin or a mixed oil of the poly-α-olefin and an ethylene-α-olefin copolymer. 
     
     
         3 . The lubricating grease composition for a polyamide resin member according to  claim 1 , wherein the other member is a metal member.
