6208/W64H Bearing Product Overview & Core Advantages
The 6208/W64H is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This metric bearing is engineered to primarily handle radial loads and offers a robust solution where high precision and consistent performance are required. A key differentiator is its integrated Soild Oil lubrication, which provides long-term, maintenance-free operation across a wide temperature range from -30°C to 120°C. Its ABEC 1 (ISO P0) tolerance ensures reliable performance for a broad spectrum of industrial uses.
6208/W64H Bearing Model Code Explained, Specifications & Naming Convention
The model number 6208/W64H provides specific technical information:
- 6208: Standard designation for a single row deep groove ball bearing with a 40mm bore and 80mm outside diameter.
- W64: Indicates the bearing is filled with Soild Oil, a polymer-based lubricant that is permanently retained.
- H: Signifies that the bearing's radial internal clearance is tighter than the standard CN group.
6208/W64H Bearing Structural Features & Performance Benefits
The performance of the 6208/W64H is defined by its construction and material selection:
- High Load Capacity: Manufactured entirely from Chrome Steel for the rings, balls, and cage, this bearing achieves a high radial dynamic load rating of 6542 lbf and a static load rating of 4002 lbf.
- Maintenance-Free Operation: The Soild Oil lubrication system eliminates the need for re-lubrication, prevents lubricant leakage, and is ideal for applications where contamination must be avoided.
- Optimized Speed Performance: With a limiting speed of 8,300 rpm, it is suitable for a variety of high-speed applications. The precise manufacturing to ABEC 1 standards contributes to smooth, low-vibration operation.
- Standardized Dimensions: Features a 40 mm bore, 80 mm outside diameter, and 18 mm width, conforming to international metric standards for easy integration and replacement.
6208/W64H Bearing Typical Application Areas
The 6208/W64H is versatile and finds use in numerous sectors, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (e.g., conveyor systems)
- Agricultural Machinery
- General machinery requiring a robust, maintenance-free bearing solution.
