he Thin Section Four Point Contact Ball Bearings are capable of supporting double direction axial and radial load, and certain tilting torque. This type of bearings is generally used for the horizontal installation.For the Thin Section Sealed Four Point Contact Ball Bearings, there are two centers of the raceway radius on each side of the raceway and both deviate from the centerline of the steel balls, which enables the Thin Section Sealed Four Point Contact Ball Bearings (X Type) to form four-point contact between the raceway and steel balls. Like the A-Type bearings and the C-Type bearings, the X-Type bearings have the same depth of the groove, which is the 25% of the diameter of the steel ball. The structures of both A-Type bearings and C-Type bearings can carry the radial, axial and moment load, which is like the back-to-back combination of a pair of the A-Type bearings.
