Four Point Contact Bearings (Sealed, X Type)

Four Point Contact Bearings (Sealed, X Type)



Thin section Four Point Contact Bearings (with seals) can support multiple-direction loads: radial load, double row thrust load, and overturning moment.


Product Description:

Both axial and radial load are weakened for the X-type bearing (Thin Section Sealed Four-point Contact Ball Bearing) with ball-installing holes. The rotational speed is restricted because the contact patch between the balls and the raceway is not continuous.

The groove depth of Thin Section Sealed Four-point Contact Ball Bearing is 25% of the ball diameter. Both structures of the deep groove ball and the four-point contact enable the bearings to support radial load, axial load, and moment load. It is like a back-to-back configuration of A-type bearings.

An axial force from right to left acting on the inner ring is delivered to point D through the contact point B between raceway and balls, and then to the outer circle and the support components. A contact angle of approximately 30° formed between the action line BD and the radial centerline of the bearing. Due to the elastic deformation of the load delivery line between balls and raceway, point A and point C are not under the load; thus, the balls can freely roll, and the rotational shaft is vertical to the line BD. When an axial force from left to right acts on the inner ring, there is a similar force delivery process to points A and C.
