Japan's NSK bearings are attributed to the fine parts in the imported bearings; the bearings support the mechanical service, preventive protection methods, condition monitoring and a series of protection operations; the system has completed the optimization of the plant's property power and protection operations. So Japan NSK Bearings For some professions; it plays a crucial role.
However, if NSK bearings exhibit the following shortcomings, they cannot be used continuously; new imported bearings should be replaced immediately. Details are as follows:
(1) Cracks or notches on any of the inner ring, outer ring, roll body and cage of the bearing;
(2) Cracking on any one of the bearing ferrule and the rolling body;
(3) Significant jams on the raceway surface, ribs and roll of the NSK bearing;
(4) The bearing cage is worn significantly; perhaps the rivet is significantly relaxed;
(5) There is rust and injury on the raceway surface of the imported bearing and the rolling body;
(6) There are severe indentations and marks on the raceway surface and roll body of NSK bearings in Japan;
(7) The inner diameter of the inner ring of the bearing or the outer diameter of the outer ring has significant creep;
(8) The discoloration due to heat is significant.
Therefore; when the NSK bearing presents the above situation; please do not continue to use; should immediately replace the new imported bearings. Prevent the presentation of unnecessary incidents.

Inconel Pipe
INCONEL®
Yuhong Group supplies Inconel® alloys C-276, HX, 22, 600, 601, 625 & 718 in the form of Plate, Sheet, Bar, Wire, Pipe, Tubing, Pipe Fittings, Flanges and Electrode.
The registered trademark name, Inconel, is applied as the prefix name to more than twenty different highly corrosion resistant high temperature strength metal alloys produced by Special Metals Corporation. These Inconel alloys or superalloys are nickel-based alloys that exhibit traits such as high resistance to corrosion, oxidation, carburization, pitting, crevice, corrosion cracking, and high temperature strength. Often, Inconel is referred to as [Inco".
Alloys of identical chemical and mechanical properties are available from other manufacturers and offer excellent alternativesto the various Inconel® brand alloys.
The corrosion-resistant superalloys are widely used in extreme environments where tremendous heat and corrosion resistance is paramount to the integrity of the end product. Chemical processing, nuclear, petrochemical, aerospace and marine industries widely use these superalloys.
What are the Characteristics of Inconel ?
Good resistance to acids, such as sulfuric, phosphoric, nitric, and hydrochloric
Almost completely free from chloride induced stress corrosion cracking
Excellent mechanical properties at both extremely low and extremely high temperatures
Outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion
High resistance to oxidation at elevated temperatures
In what Applications are Inconel alloys used ?
Chemical and petrochemical processing
Components where exposure to high mechanical stress and sea water are required
Flare stacks on offshore oil platforms
Gas turbines, rocket motors/engines, and space craft
Pollution control equipment
Nuclear reactors
