Stainless steel bearings body materials are:
440 stainless steel bearings
316 stainless steel bearings
304 stainless steel bearings
Question 2: What are the materials of stainless steel bearings available in the market? Hello
Now on the market bearings, stainless steel material 304 and 440 two kinds of material
I am the production of bearings in the province and wholesale
Look at my personal details
Private letter
Question three: stainless steel bearings material Stainless steel 420 is rust-resistant For details, you can consult with the Ha Shaft Group sales company
Questions Q4: What are the materials of bearings? Bearing materials:
Rolling bearing rings and rolling elements, one side repeatedly under high contact pressure, one side of the rolling contact accompanied by sliding. Keeper, on the one hand, with the collar and rolling body on both sides, or one side of the sliding contact, on the one hand, to withstand tensile and compressive forces. Therefore, the bearing collar, rolling body and cage materials, performance, the main requirements are as follows.
Rings, rolling body materials required performance:
Rolling fatigue strength, high hardness, high friction resistance, high cage materials required performance:
Dimensional stability and good mechanical strength, in addition, but also need to be good processing. Depending on the use, there are also requirements for impact resistance, heat resistance, corrosion resistance.
Rings and rolling body materials:
Rings and rolling body usually use high-carbon chromium bearing steel. Most of the bearings are made of SUJ2, which is a JIS grade, and large bearings are made of SUJ3.
The chemical composition of SUJ2 has been standardized in various countries around the world as a material for bearings. For example: and AISL52100 (U.S.), DIN100Cr6 (West Germany), BS535A99 (UK), etc. are the same kind of steel.
Further need for impact resistance, as a bearing material, the use of chromium steel, chromium-molybdenum steel, nickel-chromium-molybdenum steel, the use of carburizing quenching, so that the steel from the surface to the appropriate depth of a hardened layer. Carburized bearings with appropriate depth of hardening, fine organization, appropriate hardness of the surface and the heart of the hardness of the carburized bearings, than the use of bearing steel bearings with excellent impact resistance, the general chemical composition of the steel used for carburized bearings.
NSK has implemented a vacuum degassing process, so the materials used are high in cleanliness, low in oxygen content, and of good quality. In addition, the rolling fatigue life of the bearings has been significantly improved by the use of appropriate heat treatment.
In addition to the above steel types, high-speed steel with excellent heat resistance and stainless steel with good corrosion resistance are also used for special applications.
Cage materials:
Low carbon steel is used for stamping cages. Depending on the application, brass plate and stainless steel plate are also used. Cutting cage material, the use of high-strength brass, carbon steel, in addition to the use of synthetic resins.
Question 5: stainless steel bearings with what material ball ball bearing steel, referred to as bearing steel, is used to manufacture various types of rolling bearings collar (bushings) and rolling body (ball) steel. Due to the special nature of its use, bearing steel is required to... Steel selection and steel quality requirements than the general steel.
Question 6: the difference between stainless steel bearings and ordinary bearings The material is different, but the domestic bearings seem to be about the same, we have used, stainless steel bearings rust resistance is also very poor. Imported bearings have not tried, too expensive.
Question 7: What is the difference between stainless steel bearings and ordinary bearings, and what is the effect of different materials on them The materials are different, but the domestic bearings seem to be about the same, we have used, stainless steel bearings rust performance is also very poor. Imported bearings have not tried, too expensive.
Question 8: stainless steel bearings is what code said, from the appearance of how to identify the stainless steel material? Bearing stainless steel steel number for 304 pre-code S or SS For example, ordinary bearing steel bearings 6205 stainless steel code called S6205 or SS6205 stainless steel bearings than the appearance of bearing steel glossy stainless steel bearings do not have magnetic so the magnet does not suck However, the general dust cover with some of the cover is not stainless steel when we check the dust cover can be slowly picked off and then sucked by the magnet
Question 9: What is the code of stainless steel bearings? > Question 9: What is the difference between bearing steel and stainless steel This is basically two concepts
Bearing steel is named after its use, while stainless steel is named after its characteristics
It's like asking what is the difference between potable water and purified water
If you have to say it, the bearings can be made of stainless steel, but the result is not good because the bearings need to be abrasion-resistant, and are generally made of high carbon steel, while stainless steel is an alloy. High-carbon steel, and stainless steel is an alloy steel, the main feature lies in chemical corrosion resistance, rather than excellent mechanical properties
Question 10: general bearing procurement of those stainless steel materials is better? 9Cr18mo, and bearing steel.
9Cr18Mo stainless steel 9Cr18Mo is a high-carbon chromium stainless steel used for making bearing rings and rolling bodies. Used as stainless slicing mechanical edging tools and shear knives, surgical blades, high wear-resistant equipment parts, etc. 9Cr18 is a high carbon chromium martensitic stainless bearing steel. Quenched with high hardness and wear resistance, high temperature, low temperature dimensional stability. 9Cr18Mo characteristics and uses are basically the same as 9Cr18 steel, but quenched with higher hardness and tempering resistance stability, molybdenum can increase the passivation of stainless steel. 9Cr18, 9Cr18Mo high carbon chromium stainless steel ball use: suitable for manufacturing in seawater, river water, nitric acid, steam, and oceanic and other corrosive media bearings, such as bearings in ships, submersible pump parts, bearings in petroleum and chemical machinery, nautical instrument bearings and so on.
