PROBLEM TO BE SOLVED: To provide a bearing for a printing press increased in radiation quantity from an intermediate track wheel to suppress a temp. rise and constituted so as not to always generate the lock state of an eccentric metal. SOLUTION: A large number of radiation fins 16, 17 are arranged to the outside surface of an intermediate track wheel 7b forming inside and outside bearings on the inside and outside thereof in a radius direction. The intermediate track wheel 7b becomes large in radiation quantity by the convection with the open air of the radiation fins 16, 17 or the sprinkling of lubricating oil to be suppressed in temp. rise. By this constitution, trouble can be eliminated. |
