BEARING DEVICE AND HALF-SPLIT BEARING FOR USE IN BEARING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a bearing device which reduces fletching while permitting a slide at the assembling of a bearing member and a housing.SOLUTION: This bearing device 10 comprises a bearing member 12 which is divided into a peripheral direction, and a housing 11 for holding the bearing member 12 at the inside of the peripheral direction. The bearing member 12 has a bearing external peripheral face 22 which is applied with surface-roughening treatment at a side opposing the housing 11. The housing 11 has a housing internal peripheral face 21 which is applied with surface-roughening treatment at a side opposing the bearing member 21. When setting the average roughness Rc of a roughness curved-line element as Xμm at either of the bearing external peripheral face 22 and the housing internal peripheral face 21, a load length rate Rmr(X) of a roughness curved line is Rmr(X)≤10% at the other of the bearing external peripheral face 22 and the housing internal peripheral face 21 which remains.SELECTED DRAWING: Figure 1
