Category: HC719 High-Speed Series bearing Angular Contact Ball Bearing
Rolling Element: Steel Ball, Ceramic Balls; Generally, the steel balls are recommended for medium or high speed while the ceramic balls are recommended for high speed or special working conditions.
Seal Type: Sealed, Open
In HC719 Series, the design of small balls enables the bearings to have high-speed performance, high rigidity, and low heat. The rings are made of bearing steel with high purity. The unique technology of heat treatment, cold treatment, and material modifications lead to a dramatic increase in taking fatigue life.
Contact Angle: 15°and 25°. Paired bearings can support axial and radial loads.
Cage: Bakelite (outer-ring guided), Nylon (rolling-element guided), brass
Speed Factor:
when the rolling elements are steel balls,
• Grease: DmN≤1200000 (that is, limit speed N≤1200000/Dm
• Oil (minimum): DmN≤1800000
when the rolling elements are ceramic balls,
• Grease: DmN≤1400000 (that is, limit speed N≤1400000/Dm
• Oil (minimum): DmN≤2200000
They are mainly used for high rotating accuracy and high rotational speed. For example, CNC lathe spindle, high-speed electrical spindle for grinding, grinding wheel spindle, high speed and high precision machinery, etc.
