PROBLEM TO BE SOLVED: To prevent generation of damages by filling low-melting point fats and oils in a clearance between both axial ends of a roller and an inner race. SOLUTION: Since a roller 1 is held by a holder, although it does not fall in assembling and disassembling since the holder necessarily has a play, the roller can freely move and rotates in the axial direction. In order to prevent the generation of damages due to the axial movement of the roller, a clearance between both end surfaces of the roller 1 and an inner race 3 is filled with low-melting point fats and oils so as to fix or constrain the roller 1 by viscosity so as to prevent the movement thereof. By assembling and disassembling a bearing while practically fixing the roller 1, damages to the race surface of the bearing due to the axial movement of the roller can be prevented. When use of the bearing is started after assembling the bearing again, since the low- melting point fats and oils is naturally melted by the heat generated in the bearing with start of the operation and replaced with the lubricating oil, having no adverse effects on the bearing.
