15 Degree Contact Angle 7654B Gcr15 Angular Contact Ball Bearing 270x330x30mm For Motor Spindle

Product name: Angular contact ball bearing Product Category: Precision machine tool bearing product Material: bearing steel product Characteristics: high speed and low noise product Function: Can be matched at will application range: machine tool spindle dedicated

Category: B70 Series Bearing  Angular Contact Ball Bearings 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. Sealed: No Structural Features: the rings are made of bearing steel with high purity (Electro-slag remelting ESR). The special technology of heat treatment, cold treatment and material modifications leads to the dramatic increase in the fatigue life of bearing. Contact Angle: 15°and 25°. Paired bearings can support axial and radial loads. Cage: the outer-ring-guided Bakelite. Able to work steadily under 80°C for a long term.

Speed Factor when the rolling elements are steel ball, • Grease :DmN≤120000 (that is, limit speed N≤1200000/Dm • Oil (minimum) : DmN≤1800000 when the rolling elements are ceramic ball, • Grease : DmN≤140000 (that is, limit speed N≤1400000/Dm • Oil (minimum) : DmN≤2200000 Applications: 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.
