The fatigue life is rolling during the working process of the bearing; accepting a certain load; even if it is a static load; but for the steel ball and the raceway; the stress is cyclical; the data will be tumbling and fatigue, so that the bearing reaches the life. The representation is that part of the tumbling data is like the scales of the fish scales falling; this representation is called the feeling of falling off (Flaking).
The number of noise life is on the bearing of the household appliance; the load accepted by the bearing is very good. However, after the bearing has been working for a while, wear, oscillation noise, smooth grease deterioration, etc. will occur, because the noise demand for the home appliance bearing is severe; When the bearing noise exceeds the allowable scale; it is considered that the bearing can not be used continuously. The total moment of low noise operation of the bearing is called the bearing noise life.
Smooth life digital household appliances generally use a non-protective grease smooth seal bearing. Although the bearing is smooth, only a small amount of smoothing agent is needed; but after a long time of work, the smooth grease is deteriorated and leaked; the bearing is not smooth; thus the bearing is ineffective. The total moment of work in an outstanding smooth state is called the bearing life.
About light-duty bearings; bearing noise life and smooth life is shorter than bearing fatigue life. For example, household appliances bearings; only bearing selection and correct equipment; can fully satisfy the host's life matching requirements.

API

 

A.

API refers to the raw materials in the production of various types of preparations, which is the active ingredient in powder,crystal and paste for medicine use through chemical synthesis,plant extract, and preparations of biotechnology institute.It is one substance or mixture during the medicine making period uut it can not be taken directly by patients.

B.

(1) The substance(s) has pharmacological or other direct effects in the diagnose, treatment and symptom relief, or may affect the function or structure of the body.

(2) The substance is used as an ingredient or active ingredient in the producing period of final medicine.

(3) The substance is for making capsules,tablets or injection for the treatment of disease.But make it clear of dosage,take-in method and any substance causing side-effect to body.

(4) We consistently control our quality and main quality index during all period of producing and we have complete certificates to prove our quality and strict ,honest working attitude in order to make every clients of us take us as regular and permanent supplier.

 

(5) a.Initial raw substance,intermediate,final product name or symbol,chemical structure, molecular weight.For example,if there exists stereoscopic chemical structure,we will labor the type of structure.

b.All solvents,catalyst and reagent,etc for producing process.

c.All operating parameters in producing process (Temperature,time,pressure,PH Value, etc)

d.All controlling point in producing process.

e.List the specific amount ,operating parameters, and yield range of all reactors within to make quality controlling index clear of important process,parameters and intermediate.
