X-type 4-point Contact Ball Bearing Series Thin-wall Bearings

Introduction to X-type 4-point contact ball bearing series thin-wall bearings

4-point contact ball bearings are designed to handle both radial and axial loads by featuring four points of contact between the balls and the raceways.

This design provides greater axial rigidity and allows for easier mounting and dismounting.

4-point contact ball bearings with an X-type configuration and thin-wall design are often used in applications where a combination of radial and axial loads is present.

Common applications include robotics, turntables, and machinery where precise axial positioning is crucial.
