PROBLEM TO BE SOLVED: To obtain an oily adhesive for assembling a bearing, which temporarily bonds a rolling element to a bearing ring or retainer etc., so as to prevent falling etc., during incorporation of bearing component, does not inhibit a lubricant action in the rotary action of roller bearing, does not produce solid foreign matter and does not cause clogging of an oil filter. SOLUTION: The oily adhesive for assembling a bearing retains a urethane compound in a dispersed state in a base oil and has adhesiveness and an irreversible pressure-sensitive liquefaction property. Since when a composition having a desired adhesiveness is heated to a bearing temperature to be assumed during the use of a bearing of about 70°C, the composition is liquefied and when pressure to be applied to a lubricant between a bearing ring and a rolling element of about 30 MPa is loaded on the composition, the composition is liquefied and a liquid-phase state is maintained even after releasing the pressure, the lubricant action is not inhibited even if an adhesive for temporary fixation is used as it is and neither solid foreign matter is produced nor the clogging of an oil filter is caused.
