PROBLEM TO BE SOLVED: To prevent the number of days for manufacture from being increased by arranging cylindrical rollers at least one fewer than the regular number of them on a jig in which a U-shaped housing part corresponding to the raceway diameter sizes of inner and outer races, and filling and solidifying solid lubricant in the housing part. SOLUTION: When cylindrical rollers 3 are inserted into a housing part 11 formed by assembling an intermediate jig 14 to a lower jig 13 of a jig 12, the rollers 3 are arranged along a projecting part 17 of the lower jig 13 and the intermediate jig 14, and the rollers 3 one fewer than the irregular number of them are housed by a projecting piece 18 of the intermediate jig 14 The housing part 11 is blocked by bonding and fixing an upper jig 15 to the lower jig 13, and solid lubricant 5 is filled into the housing part 11 from a solid lubricant filling hole 20 of the lower jig 13 and solidified. A U-shaped solid body 21 taken from the jig 12 is extended by elastic deformation of the solid lubricant itself and assembled to the inner race 1, one roller 3 is inserted between both end 22, and the inner race l is inserted into the outer race 2. Accordingly, the same manufacturing process for the bearing as that in which no solid lubricant is filled can be made without increasing the number of days for manufacturing. |
