At present, the market's largest use of bearing steel bearings (GCr15) and carbon steel bearings, the price difference between the larger, and in the shape of color seems difficult to distinguish between the two different, do not know these two different materials TIMKEN What is the effect of the actual use of the bearing?
The following is the answer to the network:
Reply to a use of time life is very different, bearing steel long life.
Reply two, many garbage bearings are carbon steel bearings, mainly hardness and wear resistance are not as bearing steel bearings, the service life is very low.
Reply to three, carbon steel bearings and TIMKEN bearing steel bearings from the use of the main difference in the service life.
Reply four, low carbon steel is in the surface carburizing surface quenching, not all hardened. Currently on the market a lot of low-grade carbon steel TIMKEN bearings simply hard to wear, wear resistance is extremely poor. Should strengthen the management of the market, to combat shoddy wrongdoing.
Reply to five, carbon steel bearing is not bad, it depends on which machinery to use, because some do not need high-end, with carbon steel week TIMKEN bearing on the right. Of course, Losanger is better but the cost is much higher. The difference between the two in the process and the use of different results. Standard TIMKEN bearing steel is Gcr15.
Reply six, TIMKEN bearing rings and rolling body, one must repeatedly withstand high contact pressure, while the accompanying rolling contact with the sliding, while maintaining high-precision rotation. Therefore, the TIMKEN bearing rings, rolling and cage materials, performance, to meet the following requirements:
First, due to the large local contact stress, the elastic limit is high
Second, due to repeated exposure to large contact load, requiring high rolling fatigue strength;
Third, high hardness;
Fourth, good wear resistance;
Fifth, the impact of the impact of good load;
Sixth, good dimensional stability.
In addition, there is a need for good processing. Above the required performance of bearing steel can meet, but carbon steel bearings can not be guaranteed.
Reply to eight, carbon steel bearings or have a certain purpose, to see where the friends, it is impossible to hit the mosquito it, the train wheel unit ok? The difference is:
1. Hardness is not large for TIMKEN bearing steel
2. The limit speed is not high for TIMKEN bearing steel
3. Its noise is also large
4. Life is particularly short
5. Bear the pressure is particularly small
6. Feel no TIMKEN bearing steel flexibility
7. The appearance of the brightness is not bright TIMKEN bearing steel
