Hybrid bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride si 3 n 4 which make the bearings electrically insulating.
Ceramic hybrid ball bearing research paper.
This paper presents a high speed high precision spindle system with hybrid ceramic bearing along with its lubricant design and numerical calculation method.
In addition to being excellent electric insulators hybrid bearings have a higher speed capability and will provide longer service life than all steel bearings in most applications.
Silicon nitride rolling elements can extend bearing service life by offering enhanced bearing performance even under difficult operating conditions.
Material of bearing ccomponents in advanced hybrid ceramic bearings.
Dry run hybrid bearings have already been successfully employed.
In addition to being excellent electric insulators hybrid bearings have a higher speed capability 1 2 1 5 time limit of rotations compared to steel bearing and will provide longer service life lower friction and a lower level of energy consumption than all steel bearings.
A key for this is the combination of corrosion resistant steels with si3n4 table 1.
Hybrid ceramic bearings have traditional 52100 steel or stainless steel rings with ceramic silicon nitride si3n4 balls.
