The inner ring of the tight ring and the journal are in a transitional cooperation; when the shaft changes, the strand moves tightly; and it conflicts with the end face of the stop; when it is subjected to the axial effect force (Fx); the conflicting moment is greater than the inner diameter cooperative resistance torque; Inviting the tight ring and the shaft cooperation surface forced transformation; increasing the journal wear. Therefore; the thrust bearing device should pay attention to the following points. (1) Identify the tight ring and loose ring of the bearing (according to the inner diameter of the bearing; the hole diameter difference O.1 ~O.5mm).
Planar thrust needle roller bearings are primarily subjected to axial loads in the assembly; they are widely used.
Although the operation of the thrust bearing device is relatively simple; however, there are often faults in the practice of repair; that is, the bearing ring and the loose ring device are not in the correct orientation; the result is that the bearing loses the effect; the journal is quickly worn out.

(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.

Hastelloy is the prefix name of a family of alloys. Nickel is typically the base alloy, and other ingredients (such as molybdenum, chromium, cobalt, iron, titanium, aluminum and tungsten) are added to the base in varying percentages.

Hastelloy is corrosion resistant and used in high-temperature, high stress environments, such as the aerospace, chemical processing and power generation industries. It has outstanding stress corrosion cracking resistance and resistance to non-oxidizing acids (such as hydrochloric and sulfuric acid).
