Planar thrust bearings are the first to accept axial loads in the assembly; they are widely used. Although the thrust bearing device is relatively simple to operate, there are often faults in the practice of repair; that is, the bearing ring and the loose ring device are not oriented correctly; The bearing loses the effect; the journal is quickly worn out. The inner ring of the tight ring and the journal are in transitional cooperation; when the shaft changes, the strand moves tightly; and the end face of the stop is in conflict; in the axial effect force (Fx) Time; will show that the conflicting moment is greater than the inner diameter cooperative resistance torque; the tight ring and the shaft cooperation surface forced transformation; increase the journal wear.
Therefore, the following points are made on the precautions for the thrust bearing device:
(1) Identify the tight ring and loose ring of the bearing (determined according to the inner diameter of the bearing; the hole diameter difference is 0. 1 ~ O. 5mm).
(2) Identify the stop pieces of the tissue (ie, the parts that do not attack the movement; the first refers to the assembly).
(3) No matter what the situation; the loose ring of the bearing should always rest on the end face of the stop.

During the process of road work, drop glass bead onto the road line painted with thermoplastic paint which is heated to certain temperature while the paint is still wet, thus to increase the reflectivity of road marking. According to the specification of Communication Industry Standard of the People`s Republic of China No. JT/T446-2001, the granulometry for drop on glass bead is shown in the table below:

Other parameters keep conformity with the type of intermix.

The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
