Angular Contact Steel Ball Bearing 7005C-2RZ DBB

The Angular Contact Steel Ball Bearing 7005C-2RZ DBB is a high-precision component engineered for high-performance industrial applications. Featuring a 25mm bore and 47mm outside diameter, this bearing is constructed from premium high-carbon chrome steel to ensure maximum structural rigidity and fatigue resistance. The 'C' contact angle is specifically optimized for ultra-high-speed stability, making it an ideal choice for high-frequency CNC spindles and robotic arm joints. Its 2RZ double rubber non-contact seals enable a remarkable grease-lubricated limiting speed of 45,800 RPM while maintaining low friction and providing a reliable barrier against dust. Certified to P4 precision standards, it provides the rotational accuracy and minimal vibration required for high-finish machining and precision instrumentation.
