Double Row Angular Contact Ball Bearing – 3306 A/C3

The 3306 A/C3 Double Row Angular Contact Ball Bearing is designed to handle high axial and radial loads while ensuring smooth and stable operation at high speeds. Featuring a back-to-back (O) arrangement, this bearing provides excellent resistance to tilting moments and accommodates axial loads in both directions, making it suitable for stiff bearing arrangements.

Engineered for compact spaces, it delivers superior performance in applications requiring high rigidity and load-carrying capacity. With a contact angle of 30°, it optimizes load distribution for enhanced durability. Its C3 clearance allows for thermal expansion in high-speed applications.
