Angular Contact Steel Ball Bearing 7008C-2RZ DBB

The Angular Contact Steel Ball Bearing 7008C-2RZ DBB is a high-performance mechanical component specifically engineered for precision spindle assemblies and high-speed industrial applications. Featuring a 40mm inside diameter and a 68mm outside diameter, this bearing is constructed from premium hardened chrome steel to ensure maximum rigidity and durability under simultaneous radial and axial loads. The 'C' contact angle is optimized for high-speed stability, making it an essential choice for CNC spindles and precision robotics. Its 2RZ double rubber non-contact seals allow for an impressive grease-lubricated limiting speed of 30,600 RPM while providing a reliable barrier against dust and contaminants. Certified to P4 precision standards, it provides the rotational accuracy and minimal vibration required for high-finish machining.
