Method of making synthetic resin composition with lubricative underwater properties containing RBC or CRBC fine powder

A method of making a bearing having a low coefficient of friction and having lubricity when immersed in liquid comprising:

• a) forming a rice bran ceramic (RBC) fine powder by:
• i. mixing defatted rise bran with a first thermosetting setting resin;
• ii. molding said rice bran and said first thermosetting resin under pressure to form a first molded composition;
• iii. drying said first molded composition;
• iv. sintering said first molded composition;
• v. crushing the sintered first molded composition into a fine powder;
• b) forming said bearing by:
• i. mixing the RBC fine powder with a synthetic resin resin under sufficient heat to form a first homogeneous mixture having plasticity;
• or
• ii. forming a carbon rice brand ceramic (CRBC) fine powder by:
• mixing at least a portion of said RBC powder with a second thermosetting resin;
• molding said RBC powder and thermosetting resin to form a second molded composition;
• sintering said second molded composition;
• crushing said sintered second molded product to a fine powder CRBC;
• mixing the CRBC fine powder or both the CRBC fine powder and the RBC fine powder with a synthetic resin under sufficient heat to form a second homogeneous mixture having plasticity;
• iii. fabricating said bearing from said first or said second homogeneous mixture.
