Double Row Angular Contact Ball Bearing | 0 |

Double Row Angular Contact Ball Bearing is a sophisticated engineering component designed to operate in demanding mechanical environments where installation space is limited. It features two rows of balls arranged in a back-to-back configuration, effectively delivering the performance of two single-row bearings within a single outer ring.

This internal design enables the bearing to support heavy radial loads along with substantial axial loads in both directions simultaneously. It also provides high tilting stiffness to resist moment loads. Due to its rigid construction, it is ideal for applications requiring precise shaft guidance and minimal deflection, such as centrifugal pumps and automotive wheel hubs.
