6303-2Z/HT Bearing Product Overview & Core Advantages
The 6303-2Z is a single row deep groove ball bearing designed for exceptional reliability in a wide range of industrial applications. Its core advantage lies in its ability to efficiently handle radial loads while also accommodating moderate axial loads in both directions. The inclusion of shielded (2Z) construction protects the bearing's internals from contamination, enhancing its operational lifespan. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers a robust and cost-effective solution for applications requiring consistent performance and high limiting speeds.
6303-2Z/HT Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Meaning |
|---|---|---|
| Basic Designation | 6303 | Indicates a single row deep groove ball bearing with a 17mm bore, 47mm OD, and 14mm width. |
| Seal Type | 2Z | Signifies shielded on both sides. This provides effective protection against the ingress of solid contaminants while allowing for high-speed operation. |
6303-2Z/HT Bearing Structural Features & Performance Benefits
- Robust Construction: Built entirely from chrome steel for rings, balls, and cage, ensuring high strength and durability under load.
- Optimized Load Capacity: The deep groove raceway and robust design provide a radial dynamic load rating of 3057 lbf and a radial static load rating of 1495 lbf, making it suitable for significant radial forces.
- High-Speed Capability: The pressed steel cage and shielded design contribute to a limiting speed of 15,000 rpm, ideal for demanding applications.
- Contamination Resistance: The 2Z shields protect the internal components, making the bearing suitable for environments where dust and debris are present.
- Standardized Internal Clearance: Features a CN radial internal clearance, which is the standard group for general applications, ensuring predictable performance and ease of interchangeability.
