6306 Bearing Product Overview & Core Advantages
The 6306 is a single row deep groove ball bearing designed for exceptional performance in a wide range of industrial applications. As a metric bearing, it excels at handling primarily radial loads and offers reliable operation under high-speed conditions. Its open design allows for versatile lubrication options, while the ABEC-1 precision class ensures consistent quality and smooth running. This bearing is characterized by its robust construction, high dynamic load rating, and compliance with RoHS and REACH standards, making it a dependable and versatile choice for engineers seeking a balance of performance, durability, and cost-effectiveness.
6306 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 63 | Series designation indicating a medium width, deep groove ball bearing. |
| 06 | Bore diameter code. For a 63 series bearing, this corresponds to a 30 mm bore diameter. |
| Open | No seals or shields are fitted, allowing for high-speed operation and the application of various lubricants. |
6306 Bearing Structural Features & Performance Benefits
Optimized for Radial Loads: The single row deep groove raceway geometry is engineered to efficiently support high radial dynamic loads (6002 lbf), providing stable and reliable performance.
High-Speed Capability: The combination of a stainless steel cage and the open design contributes to a high limiting speed of 9,600 rpm, making it suitable for demanding applications.
Robust Material Construction: Manufactured from chrome steel for both rings and balls, this bearing offers high hardness, wear resistance, and a long operational lifespan.
Standardized Precision: The ABEC-1 tolerance class and standard CN radial internal clearance ensure consistent performance, reduced vibration, and ease of interchangeability.
