The installation mode of the roller bearing composed of raw materials is electric welding. The specific method is to weld the shaft head with the round hole plate by electric welding, and then assemble with the dragons;

2) main roller

The main roller is the main rolling bearing body in the micro needle of polymer material. It bears the vertical load and has strong wear resistance, corrosion resistance and impact resistance. In addition, because the main roller is a needle roller bearing with all roller structure, the main roller can also be used as a single rolling bearing;

3) Side roller

The side roller is the auxiliary roller bearing body in the polymer material roller bearing, which is the key to bear the level load. It also requires strong wear resistance, corrosion resistance and impact resistance. In essence, the side roller is a needle bearing without inner hole. In the compound needle roller bearing, according to the mandrel and the shaft head, they cooperate with each other;

4) Rear cover plate

The main working roller heads are installed together to produce a whole;

Assembly line method of roller bearing:

The side roller is installed in the inner side of the shaft head according to the mandrel, the main roller is sleeved on both sides of the shaft head, the rear cover plate is fixed by the nut at the top of the shaft head, and finally many parts are fixed together.
