6214-ZNR/C3 Bearing Product Overview & Core Advantages
The 6214-ZNR/C3 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing excels in handling primarily radial loads while also accommodating moderate axial loads. A key structural feature is the integral snap ring on the outer ring, which provides secure axial location within a housing, simplifying assembly and reducing the need for complex housing designs. Manufactured to ABEC 1 | ISO P0 tolerance standards and featuring a C3 radial internal clearance, it is designed for applications with potential thermal expansion or where a slightly looser fit is required for optimal performance.
6214-ZNR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Advantage |
|---|---|---|
| 6214 | Basic bearing designation: 60 series, 70mm bore, 125mm OD, 24mm width. | Defines the standard bearing dimensions and load capacity. |
| Z | Shield on one side. | Protects against contamination from one direction. |
| NR | Snap ring groove with snap ring fitted on the outer ring. | Enables secure axial positioning, reducing housing costs and complexity. |
| C3 | Greater than normal radial internal clearance. | Accommodates thermal expansion in shafts or housings, preventing preload and ensuring smooth operation. |
6214-ZNR/C3 Bearing Structural Features & Performance Benefits
Shielded Design for Contamination Resistance: The Z-shield effectively retains lubrication and excludes larger contaminants, enhancing bearing life in moderately dirty environments.
Integrated Snap Ring for Simplified Assembly: The outer ring is machined with a groove and is supplied with a fitted snap ring. This feature provides a positive axial location, eliminating the need for complex shoulder machining or end caps in the housing, which streamlines design and reduces assembly time.
Optimized Internal Clearance for Stable Operation: The C3 clearance is a critical feature for applications with expected temperature variations. It prevents thermal expansion from causing excessive preload, which can lead to overheating and premature failure, ensuring reliable performance.
Robust Load Capacity: With a dynamic load rating of 13,983 lbf and a static load rating of 9,914 lbf, this bearing is built to handle significant radial loads in demanding operational conditions.
6214-ZNR/C3 Bearing Typical Application Areas
The 6214-ZNR/C3 is ideally suited for a wide range of industrial machinery where reliable radial load support and simplified housing design are paramount. Common applications include:
- Electric Motors and Gearboxes: For supporting shafts and providing axial location.
- Industrial Pumps and Compressors: Where contamination resistance and stable operation under load are required.
- Material Handling Equipment: Such as conveyor pulleys and rollers.
- Agricultural Machinery: For use in transmissions and power take-off units.
