6306-Z Bearing Product Overview & Core Advantages
The 6306-Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. As a metric precision bearing with a P6 tolerance class, it offers high running accuracy and reliability. Its core strength lies in its ability to efficiently handle radial loads while accommodating moderate axial loads in both directions. The integral Z-type shield on one side protects against contamination, making it a robust and durable choice for various industrial settings. Its compact design and high limiting speed make it ideal for applications requiring a balance of performance and space constraints.
6306-Z Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 6306 | Basic Bearing Number | Denotes a single row deep groove ball bearing with a 30mm bore, 72mm OD, and 19mm width. |
| -Z | Shield Suffix | Indicates a non-contact steel shield on one side. This provides effective protection against large particulate contaminants while minimizing friction and heat generation, contributing to the high limiting speed. |
6306-Z Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to a P6 tolerance class with a CN radial internal clearance, this bearing ensures precise shaft guidance and smooth operation, reducing vibration and noise.
- Robust Load Capacity: The deep groove raceway and high-quality chrome steel construction provide a high dynamic load rating of 6654 lbf and a static load rating of 3597 lbf, ensuring long service life under significant radial loads.
- Optimized High-Speed Performance: The standard stainless steel cage ensures stability at high rotational speeds, supporting the bearing's impressive limiting speed of 13,000 rpm.
- Pre-Lubricated & Low Maintenance: The bearing is pre-lubricated with grease and features a shield, offering a sealed-for-life solution that reduces maintenance needs and protects the bearing in various operating environments within a temperature range of -30°C to 120°C.
