High Quality Full Ceramic 6306 Deep Groove Ball Bearing 6306CE Black Si3N4 Rodamientos 30x72x19 mm

Description

*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.

*Ceramic Bearings, Si3N4 stands for the silicon nitride ceramic material and is black colored,

Ceramic Bearings, SiC stands for the silicon carbide material and  is alsoblack colored.

*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. 

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. 

 

Feature of Hybrid Ceramic Bearing 6306:

 

C2 radial internal clearance is less than normal for applications that do not involve thermal expansion or that require reduced vibration and noise

Rubber seals on both sides of the bearing to keep lubricant in and contaminants out

Standard cage evenly spaces the balls for even load distribution and prevents contact to reduce friction, vibrations, and noise 

Single-row deep groove geometry for high speeds and supporting both radial and axial loads

 

Application of Hybrid Ceramic Bearing 6306:

 

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.

Ceramic bearings can be widely used in skateboard, aviation, spaceflight, navigation, petroleum, chemical industry, automobile, electronics, metallurgical, power, textile, pumps, medical equipment and scientific research.

If you have drawings, we can customize various non-standard ceramic bearing for you according to your requirements.
