Composite bearings (composite roller bearings) several major components:
1) Shaft head
Composite roller bearing installation is welding, the specific way is to shaft head and a round hole with the plate welding, and then and mast assembly;
2) main roller
The main roller is the main bearing in the composite roller bearing, mainly bear the vertical direction of the load, requires a strong wear resistance of the corrosion resistance and impact resistance. While the main wheel can also be used for single-way bearing alone, because it is a full complement of the roller structure of the roller bearings;
3) side roller
Side roller is a composite bearing in the secondary bearing, mainly to bear the horizontal direction of the load, also requires a strong wear resistance of the corrosion resistance and impact resistance. The side roller is essentially a roller bearing with no inner ring filled with needle roller, which is fitted together with the shaft and the shaft head inside the compound roller bearing;
4) cover plate
So that the main side of the roller shaft head together to become a whole;
Composite roller bearing assembly:
The side roller is mounted on the shaft head through the mandrel, the main roller sets outside the shaft head, the cover is fixed by the nut at the end of the shaft head, and finally the parts are fixed together.
