Refurbishable conveyor system rollers

A refurbishable conveyor system roller, said roller comprising:

• an inner cylinder having a first end and a second end and an outer cylinder having a first end and a second end, said outer cylinder being concentrically mounted snugly over said inner cylinder, said inner cylinder having a uniform outer diameter and said outer cylinder having a uniform outer diameter;
• a first end cap assembly and a second end cap assembly;
• a first coupling mounted at one end to the first end of said inner cylinder and at its second end to said first end cap assembly, said first coupling facilitating mating of said first end cap assembly at the first end of said inner cylinder, said first coupling having a first inner flange, said first end cap assembly slip fitted within said first coupling;
• a second coupling mounted at one end to the second end of said inner cylinder and at its second end to said second end cap assembly, said second coupling facilitating mating of said second end cap assembly at the second end of said inner cylinder, said second coupling having a second inner flange, said second end cap assembly slip fitted within said second coupling;
• a first bearing assembly removably mounted between said first end cap assembly and said first end of said inner cylinder;
• a second bearing assembly removably mounted between said second end cap assembly and said second end of said inner cylinder;
• and
• means for engaging said roller to a corresponding conveyor system;
• wherein said first coupling joining said first end cap assembly to said inner cylinder first end contiguous to a first end of a passage defined by said inner cylinder, said second coupling joining said second end cap assembly to said inner cylinder second end contiguous to a second end of the passage;
• wherein said first end cap assembly comprises a first cylindrical section joined integrally with a larger second cylindrical section, said first cylindrical section having an outer diameter adapted for mating with said first coupling and corresponding to the outer diameter of said inner cylinder;
• wherein said second end cap assembly comprises a third cylindrical section joined integrally with a larger fourth cylindrical section, said third cylindrical section having an outer diameter adapted for mating with said second coupling and corresponding to the outer diameter of said inner cylinder;
• wherein an outer diameter of said second cylindrical section corresponds to the outer diameter of said outer cylinder and an outer diameter of said fourth cylindrical section corresponds to the outer diameter of said outer cylinder;
• wherein said second cylindrical section, said first mounting means, said outer cylinder, said second mounting means and said fourth cylindrical section define an outer surface area of the roller.
