Picking the ideal thin area bearing materials resemble picking what you put on-- you need to clothe your components up for QimingCasting the best celebration. For example, it doesn't make sense to purchase a typical bearing material if it'll bring about very early bearing failure or various other issues. Similarly, it does not make sense to spend for a premium product if a conventional solution can handle your efficiency needs.

Correct material choice is very vital for your thin area bearings. Allow's damage down the various product options for these parts and why they might make sense for your demands.


Likewise known as carbon steel, this material is among the most usual options you'll discover for bearings. The 52100 bearing steel is a high carbon, reduced alloy steel that contains chromium. Many thanks to its make-up residential or commercial properties, this product provides superb toughness and also fatigue properties for running temperatures much less than 400 degrees Fahrenheit. These functions make chrome steel an excellent selection for the majority of basic applications seeking thin area bearings.

M50 tool steel is a molybdenum type product that works as an intermediate high-speed option. The increase molybdenum gives this product choice increased wear resistance, as well as stamina for temperatures up to 800 degrees. Furthermore, M-50 tool steel boasts excellent oxidation resistance and also high compressive characteristics. These features makes M-50 tool a great option for bearings used in greater temperature environments that demand enhanced resistances, such as those for airplane.

RM-- no seals or guards


If you have an application that operates at extremely heats or needs clean space problems, 440C stainless-steel might be the appropriate product for your needs. Stainless steel offers much better deterioration and also chemical resistance than standards steels, making it an attractive choice for any application where prospective product contamination is a major problem, such as food handling or semiconductor tools manufacturing. Stainless-steel also provides high security in heat, although it's likewise softer than lower-temperature alternatives However, this can be overcome by selecting a stainless-steel component that satisfies your performance needs.

Readily available stainless-steel bearing options.

RS-- no guards or seals

RW-- 2 seals


While ceramic isn't an alternative for the internal and also outer races, you can select a crossbreed slim section bearing made with steel raceways as well as cages and ceramic spheres. Ceramic deals a couple of advantages various other common steel balls, beginning with ceramic being a lighter product than steel. Furthermore, ceramic deal higher corrosion resistance as well as high-temperature abilities approximately 1,800 levels.

Unlike steel, ceramic is also nonconductive, that makes it an attractive choice for sure electric applications. Nevertheless, ceramic rounds are a lot more costly than conventional steel ones. Certainly, this additional cost might be well worth the cost depending on your exact efficiency and ecological requirements.
