Features of Zirconia Oxide Ball: ZRO2, Si3N4, SIC
(1) Zirconia oxide ball is 59% lighter than steel ball, which means less centrifugal force and less wear on the groove under high speed and acceleration.
(2) ZrO2 bearing ball has 44% larger elastic modulus and will undergo less deformation under load.
(3) Rockwell hardness: 78.
(4) Smaller friction coefficient.
(5) In comparison to steel, zirconia ceramic bearing ball only has 1/4 coefficient of thermal expansion and is capable to ensure sharp fluctuation of temperature.
(6) Superior surface finish.
(7) Bearable to a high temperature up to 1050 ℃, without compromising hardness and strength.
(8) Anti-rust, lubrication free.
(9) Greater corrosion resistance than steel.
(10) Metal contamination free.
(11) Non-magnetic.
(12) Electrical isolation.
