Deep groove ball bearings 6204DDU
The 6204DDU deep groove ball bearing is a premium quality, double-sealed bearing designed for durability and high-speed performance. This bearing features robust construction, excellent load capacity (Cr 12.8kN/Cor 6.65kN), and can operate at speeds up to 17,000 rpm with oil lubrication. The dual rubber seals (DDU designation) provide superior protection against contaminants while retaining lubrication. Ideal for electric motors, automotive components, and industrial machinery, this bearing offers reliable operation with minimal maintenance requirements.
Key Features
Double Rubber Sealed Design (DDU): Features high-quality rubber seals on both sides that effectively prevent dust, dirt, and moisture ingress while retaining lubricant, significantly extending bearing service life in harsh environments.
High-Speed Capability: Engineered for smooth operation at extreme speeds (up to 17,000 rpm with oil lubrication), making it perfect for high-performance applications requiring reliable rotation under demanding conditions.
Optimal Load Distribution: Precision-engineered raceways and high-grade steel construction provide balanced radial and axial load capacity (Cr 12.8kN/Cor 6.65kN), ensuring durability in various operating conditions.
Precision-Ground Components: Raceways and balls are precision-ground to ABEC-1 standards for smooth, low-noise operation with minimal vibration, ideal for sensitive applications.
Versatile Application Range: Suitable for both radial and axial loads in various orientations, offering flexibility in design and application across multiple industries.
