Deep groove ball bearings 6306-2RS
The 6306-2RS deep groove ball bearing is a robust, double-sealed bearing designed for demanding industrial and automotive applications. The dual rubber seals (2RS designation) provide superior contamination protection while retaining lubrication. Manufactured from high-grade bearing steel, this unit is ideal for electric motors, gearboxes, pumps, and automotive components requiring reliable performance in harsh operating conditions.
Key Features
Double Rubber Sealed Design (2RS): Features high-performance nitrile rubber seals on both sides that effectively block contaminants while maintaining proper lubrication, significantly extending service life in dusty or wet environments.
Enhanced Load Capacity: Engineered with optimized raceway geometry to handle substantial radial loads (Cr 26.7kN) and moderate axial loads, making it suitable for heavy-duty applications in various industries.
Precision-Ground Components: Manufactured to ABEC-1 standards with precision-ground raceways and balls for smooth, low-vibration operation essential for sensitive machinery.
Versatile Speed Performance: Capable of operating at 9,600 rpm with grease lubrication and up to 12,000 rpm with oil lubrication, accommodating a wide range of industrial speed requirements.
Maintenance-Friendly Design: Pre-lubricated with high-quality grease and sealed for life in many applications, reducing maintenance needs and downtime in industrial settings.
