The beneficial effects of the utility model：Location structure on upper half-and-half bearing and bottom half-bearing mainly prevents bearing wrongly installed Or it is anti-loaded, in addition also function to the effect of anti-sliding stop.Location structure is designed at the back side of bearing --- and connecting rod mating surface manufactures axis Can be once integrally formed with bearing during the location structure held, technical characteristics are as follows：

1. it is not required in addition reprocess deformation and surplus caused by punching press after location structure forming；

2. location structure can replace using positioning pin traditional structure, without on bearing requirement on machining accuracy it is higher Dowel hole can cancel positioning pin；

3. bearing inner surface will not be caused to be deformed in stamped groove both sides, the shape of inner surface is not influenced；

4. location structure is designed at the bearing back side --- connecting rod mating surface will not cause inner surface at location structure position Notch is generated, does not influence the rigidity of bearing.
