TIMKEN bearings bearing steel and carbon steel what's the difference between the TIMKEN bearings

At present, the dosage of the market's largest bearing steel bearing ( GCr15） And carbon steel bearing, price difference is bigger, in the shape and color, it seems, it's hard to distinguish the difference, I don't know the two different material from the effects of TIMKEN bearings have to differ? Here is a network of answer: reply a, use of time is very different from life, long service life of bearing steel. Reply 2, many bearings are carbon steel bearing, mainly is the hardness and wear resistance than bearing steel bearing, low service life. Reply three and TIMKEN bearing steel, carbon steel bearing bearing in using the main difference on the service life. Respond to four, is low carbon steel in the surface layer surface carburizing quenching, not all hardening. On the market at present a lot of low carbon steel TIMKEN bearings are quenching is not hard, wear-resisting performance is poor. Should strengthen the management of the market, to crack down on shoddy wrongdoing. Reply to five, the carbon steel bearing is not bad, it depends on which used machinery, because some do not need to high-grade, with carbon steel weeks TIMKEN bearing is suitable. Of course, steel is better but the cost is much higher. The difference on craft and use effect is different. The standard is TIMKEN bearing steel Gcr15. Reply TIMKEN bearing rings and rolling body, a repeatedly under high contact pressure, in addition to associated with the sliding rolling contact, at the same time, keep high precision rotation. Therefore, the TIMKEN bearing ring, rolling body and retainers material, performance, to achieve the requirements of the following: first, because produce large local contact stress, elastic limit demanding second, due to repeated contact load, under rolling fatigue strength demanding; Third, can obtain high hardness; Fourth, good wear resistance; Fifth, the toughness of the shock load; Sixth, size stability is good. In addition, also need good workability. The performance of the bearing steel all can meet the above requirements, but the carbon steel bearing can't guarantee. Reply to eight, carbon steel bearing has certain purposes, or to see where is used, maybe not the cannon dozen mosquito, train wheel hub unit? Appearance bright brightness not TIMKEN bearing steel
