6306-2Z/C2EVT143 Bearing Product Overview & Core Advantages
The 6306-2Z/C2EVT143 is a single row deep groove ball bearing designed for reliable performance in demanding applications. This shielded bearing excels in handling significant radial loads while offering protection from contaminant ingress. Its key advantages include a compact design, high operational reliability, and suitability for applications requiring controlled internal clearance. The bearing is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring consistent quality and performance.
6306-2Z/C2EVT143 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6306 | Standard series designation for a medium-duty, single row deep groove ball bearing. |
| 2Z | Indicates the bearing is equipped with non-contact shields on both sides. This provides effective protection against dust and other contaminants while minimizing friction. |
| C2 | Specifies a radial internal clearance that is smaller than the normal (CN) group. This is optimal for applications requiring high precision and reduced running noise. |
| EVT143 | A manufacturer-specific suffix, typically indicating a specific cage design or other proprietary feature that enhances performance. |
6306-2Z/C2EVT143 Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The single row deep groove raceway geometry is optimized to support high radial dynamic load ratings (6002 lbf), making it suitable for a wide range of industrial loads.
- Shielded Protection: The 2Z shields act as a physical barrier, protecting the internal components from contaminants and helping to retain any subsequently added lubricant, thereby extending service life.
- Precision Running: Manufactured with a C2 radial internal clearance, this bearing provides precise and quiet operation, which is critical for electric motors and precision machinery.
- High-Speed Capability: The combination of a high-grade chrome steel cage and optimized internal geometry allows for a high limiting speed of 9,600 rpm.
- Material Integrity: Constructed entirely from chrome steel for rings, balls, and cage, ensuring high hardness, durability, and resistance to wear.
6306-2Z/C2EVT143 Bearing Typical Application Areas
This versatile bearing is ideally suited for a multitude of applications across various industries, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring reliable radial support
