6307 ETN9/C3VB116 Bearing Product Overview & Core Advantages
The 6307 ETN9/C3 is a single row deep groove ball bearing engineered for superior performance in demanding industrial applications. This metric bearing is characterized by its open design and C3 radial internal clearance, making it exceptionally suitable for applications with thermal expansion or where interference fits are used. Its high radial dynamic load rating of 7509 lbf ensures reliable operation under significant loads, while the Nylon cage (ETN9) contributes to quiet operation and high-speed capability. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent precision and is an ideal choice for general machinery requiring robust and dependable radial load support.
6307 ETN9/C3VB116 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6307 | Standard bearing series designation. | Defines the basic dimensions: 35mm bore, 80mm OD, 21mm width. |
| E | Reinforced design. | Indicates a high-capacity design with more or larger balls, increasing the load rating. |
| TN9 | Nylon (Polyamide) cage, glass fiber reinforced. | Enables low friction, quiet running, and is suitable for high limiting speeds (8,500 rpm). It is also lightweight and offers good acceleration characteristics. |
| /C3 | Radial internal clearance greater than Normal (CN). | Provides extra clearance to accommodate thermal expansion from high operating temperatures or tight interference fits, preventing premature failure. |
6307 ETN9/C3VB116 Bearing Structural Features & Performance Benefits
High Load Capacity & Reinforced Design: The "E" designation signifies an optimized internal geometry with a full complement of larger balls. This reinforcement significantly boosts the radial dynamic and static load ratings, making the bearing exceptionally durable under heavy loads.
Optimized High-Speed Performance: The TN9 Nylon cage is a key contributor to the bearing's high limiting speed. Its lightweight nature reduces centrifugal forces, while its inherent lubricity minimizes friction between the rolling elements, resulting in cooler and more efficient operation at high RPMs.
Accommodation for Thermal Expansion: The specified C3 radial clearance is a critical feature for applications where operational heat causes the shaft and housing to expand. This prevents the bearing from being pre-loaded, which can lead to excessive heat generation, increased noise, and reduced service life.
Precision & Material Quality: Manufactured from high-grade Chrome Steel and conforming to ABEC 1 | ISO P0 tolerances, this bearing guarantees dimensional accuracy and consistent running precision, ensuring smooth and reliable performance in a wide range of machinery.
6307 ETN9/C3VB116 Bearing Typical Application Areas
