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 non-contact sealing is used for two end faces of the bearing. 


CHG provide high speed bearing as follows: 


1. The contact angle C is 15°, AC is 25 °.

2. Outer ring guide phenolic resin cage
