Ceramic Angular Contact Balls Bearings In Material Of HIP-Si3N4

Description of Si3N4 Ceramic Angular Contact Balls Bearings:

1. HIP-Si3N4 races and balls are made of highly purified, submicron silicon nitride powder with an alpha phase of more than 92%, and is processed by GPS (Gas Pressure) sintering and HIP (Hot Isostatic Pressure) sintering technology. Compared with GPS sintered silicon nitride material, the porosity, wear resistance, crushing value and fatigue contact life of after HIP sintered sinlicon nitride have been greatly improved, which is the preferred material for ultra-high speed and high precision ceramic bearings.

2. HIP-ZrO2 races are made by highly purified, sub-micron and after Y2O3-TZP stabled zirconia powder material, are processed by AP (Atmospheric Pressure) sintering and HIP (Hot Isostatic Pressure) sintering technology, so their porosity, wear resistance, impact resistance and resistance to fatigue contact life are greatly improved, to which is the ordinary zirconia material incomparable.
