High Performance Bearing, Si3N4 Ceramic Balls Size 1/8"

Model Number: XYB-0.8mm-101.6mm-#5314 Brand Name: XYB Key Specifications/Special Features: Their characteristics are shown as below:1. High corrosion resistance, which means they can be also used in strong acid, strong alkali and seawater2. High temperature resistanceSi3N4 ceramic balls remain the same strength and hardness even in 1100℃3. Electrical insulation, non-magnetic, they can also be used in magnetic domain4. Si3N4 ceramic balls have a low density of 3.26 g/cm3
Approximately 60% lighter than steel balls, which extremely decrease the centrifugal force on the groove, in order to effectively reduce the wear and tear

5. High rigidity and strength
Compared with bearing steel, Si3N4 ceramic is double higher in hardness and half higher in elastic modulus value

6. Coefficient of thermal expansion of Si3N4 is 3.2×10-6/K
Nearly 25% of the bearing steel, which leads to a good thermal shock resistance

7. Self-lubrication of Si3N4 ceramic ball bearings can help to solve the contamination and inconvenient caused by lubricator, can also be used in vacuum and high temperature conditions

8. Low thermal conductivity

Application domains: high precise ceramic bearings, high temperature bearings, vacuum bearings, nonmagnetic bearings, chemical pumps, high temperature pumps, ceramic valve balls and measure balls
