This High Speed Angular Contact Ball Bearing Sealed H72 series select larger ball diameter to increase the carrying capacity. Because the inner and outer rings are single flange, the internal space of the bearing is increased, so that more lubricant can be stored and lubrication performance of the bearing is improved.
The Ultra-high Speed Angular Contact Bearing through the internal structure optimization design, the high speed rolling body friction coefficient, sliding state to a minimum, so that it can achieve ultra-high speed, ring double slope structure design, increase the internal space, can be effectively lubricated.
It is mainly used for high speed and high precision grinding for internal surface. In order to meet the requirement of electric spindle, the internal parameters of the bearing rings are optimized. CHG B719 series bearing can use ceramic balls for higher speed and longer life.
