6303/W64 Bearing Product Overview & Core Advantages
The 6303/W64 is a single row deep groove ball bearing designed for reliable performance in various industrial applications. This metric bearing excels in handling radial loads efficiently while offering moderate capacity for axial loads in both directions. Its open design facilitates high-speed operation, and the integration of Soild Oil lubrication ensures long-term, maintenance-free service. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent precision and is an ideal choice for applications demanding cost-effective reliability and robust performance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6303 | Standard designation for a single row deep groove ball bearing with 17mm bore, 47mm OD, and 14mm width. |
| W64 | Indicates the bearing is pre-lubricated with Soild Oil, a solid polymer-based lubricant, for lifetime lubrication and contamination resistance. |
6303/W64 Bearing Structural Features & Performance Benefits
- Optimized Radial Load Capacity: The deep groove raceway and single row design are engineered to support significant radial dynamic load ratings of 3057 lbf, ensuring stable operation under demanding conditions.
- High-Speed Capability: With a limiting speed of 15,000 rpm, the open structure and precision chrome steel cage minimize friction and allow for smooth, high-velocity rotation.
- Maintenance-Free Operation: The integrated Soild Oil lubrication eliminates the need for re-lubrication, providing consistent performance and protection against lubricant washout across a wide temperature range of -30°C to 120°C.
- Precision & Reliability: Manufactured from high-grade chrome steel for both rings and balls, and adhering to ABEC 1 | ISO P0 tolerances with standard CN radial internal clearance, this bearing delivers consistent accuracy and long service life.
