Four-point Contact Ball Slewing Bearing
Main structural features: The contact angle of the ball and raceway is 45 degrees, so it can bear the axial force, radial force, and overturning moment. Four point Contact Ball Bearing is the most widely used slewing bearings with high static loading capacity and high rotation flexibility.Serial numberDesignationsBoundary dimensionsmounting dimensionsStructure sizeToothlessDdHD1D2nФn1D3d1H1h1010.20..20..20..20..25..25..25..25..30.′010.25..30.′010.25..30.′010.25..30.′010.25..40.′010.30..40.′010.30..40.′010.30..40.′010.30..45.′010.35..45.′010.35..45.′010.35..45.′010.35..60.′010.40..60.′010.40..60.′010.40..60.′010.40..75.′010.50..75.′010.50..75.′010.50..75.′010.50.
