There is rotational, have HRB bearing (

Jiaxing bearing group sales co. , LTD. (
The company)
Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center.
High carbon chrome steel bearing steel is commonly used for high carbon chrome steel, its characteristic is from surface to core hardening to such high hardness range HRC58-66, so it is also called completely hardened steel.
The steel price is low, the most widely used throughout the world.
This kind of steel is divided into chrome steel, chrome molybdenum steel, chromium and chromium manganese silicon manganese molybdenum steel four categories.
Carburizing bearing steel carburizing steel is the earliest use of steel bearing industry, the current and developing.
Carburizing bearing steel used to make work in vibration or shock load conditions of bearing components, such as automobiles, locomotives, construction machinery, rolling mill bearing components and agricultural machinery and so on.
Demand for this kind of steel is: the carburized surface can be hardened to have the same hardness and high carbon chromium steel and fatigue strength, the core control within the scope of the HRG3540 hardness, and enough toughness and good comprehensive mechanical strength, surface retained compressive stress state.
Carburizing heat treatment process of bearing steel complex, prone to brittle, soft point, hardness is not equal, so the cost is higher.
Greater impact on the carbon in the bearing steel in the carburizing steel also can not adapt to the situation, often manufactured in carbon manganese steel, chrome steel bearing parts, without too much more for low speed large hardness requirement of components, and various size of the screw roller, etc.
Recently developed certain medium carbon steel varieties such as GCr15 can be applied to large middle and small sizes of bearing components manufacturing, it is a promising material could be widely used.
High temperature bearing steel demand for work under the high temperature of bearing steel, modern technologies such as nuclear power system, such as jet engines and gas turbine working temperature for baidu often that thousands of degrees, apparently ordinary bearing steel can't application, must use high temperature bearing steel or other high temperature resistant materials.
Several high temperature corrosion resistant bearing steel bearing steel contrast in ordinary bearing steel is not up to the life of a corrosive medium environment, will be made from corrosion resistant bearing steel bearings and their parts, for example, in contact with water or water vapor in hydraulic machinery, in contact with acid and alkali chemical machinery, in contact with the sea naval ship;
Instrumentation in the bearing is also commonly used corrosion resistant steel manufacturing, because of a slight corrosion will affect the bearing their measuring accuracy and response sensitivity;
Bearing in the food industry are sometimes made of corrosion resistant steel, because it wants the bearing ability of corrosion, does not have corrosion caused by food pollution.
Low temperature resistant bearing steel in space technology, provide liquid fuel rocket turbine pump bearing to operate in the liquid oxygen and liquid hydrogen.
The equal temperature and liquefied gas.
Because ordinary bearing steel martensite structure, the toughness is not ideal, and low temperature brittleness, such as for 5 ~ 200 ℃ low temperature, actually because of the moisture in the air in the bearing surface corrosion resulting from the condensed water droplets, so should be stainless steel.
Generally will be low-temperature cryogenic system of martensite stainless steel processing, to ensure that the organization is not changing.
In the liquid oxygen (
Boiling point 183 ℃)
Using SUS4400 steel manufacturing centripetal ball bearings and cylindrical roller bearings made by running the test results show that the bearing except some guard surface wear no special exception, can withstand up to 20000 r/min speed, but at this moment the bearing cage must use special materials.
Low temperature resistant bearing cage is also useful to stainless steel manufacturing, the commonly used system of austenite steel SUS304 and markov system SUS440V steel, the former is easy to be processed and used.
