Long life waterproof bearings 608 8*22*7 full ceramic bearings for inline skate supply

The Description of Ceramic Bearings:

Compared to steel, Ceramic ball Bearings have many specific advantages. They offer superior corrosion and heat resistance, higher dimensional stability, and lower density, which facilitate high speed. Ceramics are superior to steel in heat and corrosion resistance, and are lightweight and extremely hard as well. Consequently, ceramic rolling bearings can be used in environments where conventional steel bearings cannot. That is to say, the superiority of these bearings makes it possible that they can be applied in some special environments.

Characteristics of Ceramic Bearings:

1.High hardness,wearing resistance,low friction coefficient,good self-lubrcating

2.High temperature application,better thermal shock resistance

3.Higher fracture toughness,better shock resistance

4.Excellent resistance to chemical corrosion,it can endure all of acid corrosion and alkalescent corrosion,it's unstable for most strong alkali and molten salt.

5.The performance of contant similar to bearing steel ,similar forms of fatigue spalling

Advantages of Ceramic Bearings:

1.59% lighter than steel

2.The elastic modulus is 44% larger than steel

3.Hardness is higher than steel

4.Low friction

5.It can withstand temperature changes

6.Easy to access to almost perfect surface finish

7.High temperature resistance

8.Never rust,can work under the condition of no oil lubrication

9.More resistant to chemical corrosion

10.No metal pollution

11.No magnetism

12.Electric insulation

13.There is no adhesive wear

14.no reaction with metallic melts
