Loading Direction √ Radial Load √ Radial Load √ Large Uniaxial Load √ Radial Load
√ Unidirectional Axial Load √ Bidirectional Axial Load √ Unidirectional  √ Bidirectional Axial Load
Features Angular contact ball bearings are suitable for high speed & high precision rotation.
HAR(High Speed) small diameter + plenty of balls + mostly used for machine tool spindle
Contact Angle The standard contact angles between the ring and the ball are 15°, 30° and 40°  
The greater the contact angle, the greater the axial load capacity.
The smaller the contact angle, the more suitable for high-speed rotation
