6303/W64HVU121 Bearing Product Overview & Core Advantages
The 6303/W64 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This metric bearing features an open design and is pre-lubricated with Soild Oil, offering reliable, long-term lubrication. Its key advantages include a high radial dynamic load rating of 3057 lbf, making it suitable for applications requiring robust radial load capacity. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent and reliable operation. The combination of chrome steel construction and optimized internal geometry provides a durable and cost-effective solution for a wide range of industrial machinery.
Model Code Breakdown
- 63: Indicates the bearing series, defining the basic dimensions and performance characteristics.
- 03: Specifies the bore diameter code. For this series, '03' corresponds to a 17 mm bore diameter.
- W64: This suffix denotes that the bearing is lubricated with Soild Oil, a polymer-based solid lubricant that provides maintenance-free operation over a wide temperature range.
6303/W64HVU121 Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High Load Capacity: The deep, continuous raceways on both rings are optimized to support high radial loads and moderate axial loads in both directions, ensuring versatile performance.
- Pre-lubricated with Soild Oil: The integrated Soild Oil lubrication eliminates the need for re-lubrication, prevents lubricant leakage, and is effective across the specified temperature range (-30° to 120 °C).
- Precision & Reliability: Manufactured to ABEC 1 (ISO P0) tolerance class with a standard CN radial internal clearance, this bearing delivers consistent performance, low noise, and low vibration for smooth operation.
- Robust Construction: All components, including the rings, balls, and cage, are made from high-grade chrome steel, providing excellent durability, wear resistance, and a long service life.
