Angular Contact Steel Ball Bearing 7014AC-2RZ DBB

The Angular Contact Steel Ball Bearing 7014AC-2RZ DBB is a high-performance industrial component specifically engineered for mid-to-large bore spindle assemblies. Featuring a 70mm inside diameter and a 110mm outside diameter, this bearing is built from premium hardened chrome steel to ensure maximum rigidity under simultaneous radial and axial loads. The 'AC' contact angle is optimized for superior thrust capacity, making it an essential choice for VMC spindles and heavy-duty industrial motors. Its 2RZ double rubber non-contact seals allow for an impressive grease-lubricated limiting speed of 15,500 RPM while providing a reliable barrier against dust and industrial contaminants. Certified to P4 precision standards, it delivers the rotational accuracy and vibration-free performance required for high-finish machining.
