The Double Row Angular Contact Ball Bearing produced by KOMEL can withstand bidirectional axial loads and high radial loads at the same time through the contact angle design of the two rows of steel balls and the inner and outer rings. They are suitable for scenarios that require high stiffness and bidirectional axial positioning (such as machine tool spindles andturbo-machinery).
Structural features
The two rows of steel balls are symmetrically distributed, and the contact angle is usually 25° or 30°.
Non-separable design, with integral flanges on the inner or outer ring.
Load capacity
The radial load capacity is about 1.6~1.8 times that of a single-row bearing.
Strong bidirectional axial load capacity, suitable for combined load conditions.
Rigidity and precision
High inherent stiffness, high-precision rotation can be achieved without preload.
Sensitive to installation errors (angle deviation needs to be <2 arc minutes).
