Thin Section Sealed Four-point Contact Ball Bearings( X type)

The thin section sealed four-point contact ball bearings( X type) can support double direction axial and radial load and specific tilting torque. This type of bearing is generally used for horizontal installation.

For the thin section sealed four-point contact ball bearings( X type), there are two centers of the raceway radius on each side of the raceway. 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 groove depth, 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, like the back-to-back combination of a pair of A-Type bearings.

Thin section sealed four-point contact ball bearings( X type) are pre-lubricated with general-purpose grease.

 Applications of thin section sealed four-point contact ball bearings

The thin section sealed four-point contact ball bearings( X type) were developed for applications where space limitations are of the utmost importance. These kinds of bearings are widely used for aviation, astronomical instruments, glass manufacturing machinery, medical instrument, optical and scanning instrument, satellite communication devices, textile machinery, large welding equipment, robot, print machinery, semiconductor manufacturing equipment, etc.
