INA bearings Assembly in the main axial load, and their use is widespread. Although INA bearing installation is relatively simple, but the actual repair common errors occur, INA bearing the compression ring and pine loop installation location is not correct, resulting INA bearing defunct, shaft neck is worn very quickly. Compression ring neck for transition fit inner ring and shaft, when the shaft rotates driven compression ring and frictions and still faces, in axial force (Fx), appears greater than the minor diameter fit resistance moment of friction moment, leading to compression ring and shaft forces turn the mating surfaces, axis neck abrasion.
Therefore, INA bearing installation should pay attention to the following several points.
(1) distinguish between INA bearings tight ring and loose ring (according to the INA bearing diameter size determine, Aperture O.1~O.5mm difference).
(2) to distinguish bodies still (that is, not part of the movement, mainly refers to the Assembly).
(3) no matter what the situation, INA bearing pine ring should always be at the static end surface.
