Product Description

Description of Made in China SEMRI Factory Full Ceramic Deep Groove Ball Bearing 6304a7 with High Performance :

Full ceramic bearings have the characteristics of anti-magnetic insulation, abrasion resistant, oil-free self-lubricating and enduring extreme high or low temperature, so they can be used for harsh environment and even under some special condition. The material of rings and roller is jar gonia (ZrO2) and the holder uses poly back fluoride(PTFE) as standard configuration. Generally, we can use the reinforced nylon made of glass fiber 66(GRPA66-25),special engineering plastics(PEEK,PI),nonrust steel(AISI SUS316.SUS304), brass(Cu) and so on. ceramic deep groove ball bearings are made entirely of ceramic material and are superior to common Steel Angular Contact Bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPM's, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present.

1.Ceramic Bearings have two types of ceramic bearing, hybrid ceramic bearing and full ceramic bearing.The hybrid ceramic bearing has steel inner and outer rings with ceramic balls.
2.Ceramic Bearings, Si3N4 stands for the silicon nitride ceramic material and is black colored,
3.Ceramic Bearings, SiC stands for the silicon carbide material and is alsoblack colored.
4.Ceramic Bearings, ZrO2 stands for the zirconium dioxide, also known as zirconia or zirconium oxide, they are white colored, a ZrO2 ball looks exactly like a pearl.
5.The ceramic material is not stronger than steel, but ceramic bearing are lighter and have lower friction than steel, which makes ceramic bearing go faster with lower heat generated.

Features of Made in China SEMRI Factory Full Ceramic Deep Groove Ball Bearing 6304a7 with High Performance :

1. Ceramic bearing has the characteristics of high temperature resistance, cold resistance, abrasion resistance, corrosion resistance and insulation, and can be used in extremely bad environment and special conditions.
2. Ceramic bearings can be widely used in aviation, spaceflight, navigation, petroleum, chemical industry, automobile, electronics, metallurgical, power, textile, pumps, medical equipment and scientific research.
