6213-ZNR/C3 Bearing Product Overview & Core Advantages
The 6213-ZNR/C3 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing is distinguished by its integrated snap ring on the outer ring, which facilitates secure axial location within a housing, simplifying assembly and enhancing operational reliability. Its C3 radial internal clearance makes it particularly suitable for applications involving thermal expansion or where interference fits are used. Constructed entirely from high-grade chrome steel, it offers excellent durability and a high limiting speed, making it a versatile and reliable choice for a wide range of machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6213 | Basic bearing designation indicating a single row deep groove ball bearing with a 65 mm bore and 120 mm outside diameter. |
| ZNR | Specifies the bearing is equipped with a snap ring (Z) fitted into a groove on the outer ring and a non-contact shield (NR) on one side for contaminant protection. |
| C3 | Indicates a greater than normal radial internal clearance, ideal for applications with elevated operating temperatures or tight fits. |
6213-ZNR/C3 Bearing Structural Features & Performance Benefits
- Snap Ring for Axial Location: The integrated snap ring (outer ring locating feature) eliminates the need for complex housing shoulders or end caps, providing a cost-effective and space-saving solution for secure axial positioning.
- Shielded Design: The non-contact shield effectively protects the bearing's internal components from large particulate contaminants, extending bearing service life without significantly increasing friction or temperature.
- Optimized Internal Clearance: The C3 clearance accommodates thermal expansion from high-speed operation or interference fits, preventing premature failure due to excessive preload and ensuring smooth running.
- High-Grade Material Construction: Manufactured from chrome steel for rings, balls, and cage, the bearing delivers high strength, wear resistance, and consistent performance under radial dynamic and static loads.
- Precision Manufacturing: Produced to ABEC 1 | ISO P0 tolerance class, ensuring reliable dimensional accuracy and rotational performance for general industrial applications.
6213-ZNR/C3 Bearing Typical Application Areas
The 6213-ZNR/C3 is ideally suited for applications requiring secure mounting and protection from contaminants. Common uses include:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
