6301-2Z/C3WT Bearing Product Overview & Core Advantages
The 6301-2Z/C3 is a single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. Its key advantage lies in its ability to efficiently handle radial loads while also accommodating moderate axial loads in both directions. The combination of shielded construction and a C3 radial internal clearance makes it an excellent choice for applications requiring reliable operation, extended service life, and suitability for environments with potential thermal expansion.
6301-2Z/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Meaning |
|---|---|---|
| Basic Designation | 6301 | Denotes a standard single row deep groove ball bearing with a 12mm bore, 37mm OD, and 12mm width. |
| Seal/Shield Type | 2Z | Indicates the bearing is shielded on both sides. This provides effective protection against contamination from solid particles while maintaining low friction and allowing for high-speed operation. |
| Internal Clearance | C3 | Specifies a greater than normal radial internal clearance. This is beneficial for applications where thermal expansion of the shaft or housing is expected, preventing preload and ensuring smooth operation. |
6301-2Z/C3WT Bearing Structural Features & Performance Benefits
- Shielded for Contamination Resistance: The non-contact ZZ shields (2Z) retain the factory-applied lubricant and protect the rolling elements from large contaminants, significantly enhancing bearing life in dusty or dirty environments.
- Optimized for Thermal Conditions: The C3 clearance provides operational stability in applications with elevated temperatures or where fits result in a reduction of internal clearance, preventing binding and reducing friction.
- Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers a high dynamic load rating of 2181 lbf and a static load rating of 944 lbf, ensuring durability under significant radial loads.
- High-Speed Capability: The precision-ground components and optimized internal geometry allow for a limiting speed of 20,000 rpm, making it suitable for demanding high-speed applications like electric motors and spindles.
- Precision & Consistency: Manufactured to ABEC 1 | ISO P0 tolerance class, ensuring reliable and consistent performance for general industrial use.
6301-2Z/C3WT Bearing Typical Application Areas
This versatile bearing is widely used across various industries due to its balanced performance characteristics. Key application areas include:
- Electric Motors and small generators.
- Gearboxes and transmission systems.
- Industrial Fans and blowers.
- Material Handling Equipment such as conveyor rollers.
- Agricultural Machinery.
