High precision Angular Contact Ball Bearing NSK 7308 Bearing is one kind of ball bearings design. Its dimension is 40×90×23mm , weight is 0.68kg , the material are adopt high quality chrome steel , Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads , i.e. simultaneously acting radial and axial loads.
Angular contact ball bearing NSK 7308 Bearing can bear both radial and axial load . it can be operation under high speed situation . The bigger the contact angle, the higher axial load carrying capacity . The contact angle is the angle between the line which connecting the contact point of the ball and the raceway in the radial plane with the vertical line of the bearing axis . High-precision and high-speed bearings usually take 15 degrees of contact angle . Contact angle will be increase under axial force .
