Double Row Angular Contact Ball Bearings

• Superior Bidirectional Load Capacity: Utilizing a unique double-row ball arrangement, it can simultaneously withstand radial and bidirectional axial loads, providing comprehensive composite force support.
• Optimal Solution for Space Constraints: Functionally equivalent to two single-row angular contact bearings configured opposite each other, but with a significantly reduced axial width, making it ideal for installation in compact machinery with limited internal space.
• High-Specification Double Groove Precision Manufacturing: This product has extremely stringent requirements for the dimensions, coaxiality, and geometric precision of the two grooves, ensuring that the load is evenly distributed on both sides during operation, achieving excellent mechanical balance.
• Exceptional High Speed ​​and High Rigidity: The low-friction, high-rigidity design maintains a high level of rotational accuracy even under extreme operating conditions of high speed or high load.

Basic Structure and Principle

• Basic Structure: Primarily composed of a one-piece molded double-groove outer ring, a double-groove inner ring, two rows of precision steel balls, and a dedicated cage. Its internal geometry is essentially the same as two single-row angular contact bearings configured back-to-back (DB).
• Operating Principle: When the mechanical operation generates a combined force, the load is transmitted along the set "contact angle." The double-row steel balls can respectively cope with the axial thrust from two opposite directions. To avoid damage to one side of the steel balls due to overload caused by process errors, our company implements extremely strict micron-level precision control on the double grooves of the outer and inner rings, ensuring that the double-row steel balls achieve perfect synchronization and uniform force during rotation, achieving the principle of bidirectional axial positioning and high-rigidity operation.
