6213-2ZN/C3 HT51 Bearing Product Overview & Core Advantages
The 6213-2ZN/C3 HT51 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This precision bearing is distinguished by its shielded design (2Z) on both sides, offering effective protection against contaminants while retaining lubrication. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures reliable operation and consistent performance. A key feature is its snap ring groove on the outer ring, which facilitates secure axial location and simplifies housing design. The C3 radial internal clearance makes it particularly suitable for applications with elevated operational temperatures or where interference fits are used, ensuring stable performance under such conditions.
6213-2ZN/C3 HT51 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6213 | Basic series designation, indicating a medium series deep groove ball bearing with a 65mm bore. | Standardized dimensions for easy interchangeability. |
| -2Z | Bearing is shielded on both sides. | Provides effective protection against solid contaminants, enhancing bearing life in dirty environments. |
| N | Snap ring groove on the outer ring. | Enables secure axial location, simplifying housing design and reducing assembly costs. |
| /C3 | Radial internal clearance greater than Normal (C0). | Accommodates thermal expansion from interference fits or high operating temperatures, preventing premature failure. |
| HT51 | Manufacturer-specific suffix for heat stabilization treatment. | Stabilizes the bearing components, allowing for a consistent operational temperature range up to 120°C. |
6213-2ZN/C3 HT51 Bearing Structural Features & Performance Benefits
Robust Construction for High Load Capacity: Manufactured from high-grade chrome steel for both rings, balls, and cage, this bearing delivers high strength and durability. It offers a substantial dynamic load rating of 12,859 lbf and a static load rating of 9,015 lbf, making it capable of handling significant radial loads.
Optimized for Contaminated Environments: The non-contact steel shields (2Z) effectively prevent the ingress of dust and other particles, protecting the rolling elements and raceways. This design is ideal for applications where sealing is required but minimal friction is critical.
Enhanced Operational Stability: The C3 internal clearance is a critical feature for applications involving thermal expansion. It ensures the bearing does not become preloaded at high temperatures, maintaining smooth operation and extending service life.
Simplified Assembly and Axial Location: The inclusion of a snap ring groove on the outer ring eliminates the need for complex housing shoulders or end caps, reducing part count and assembly time while providing secure axial positioning.
6213-2ZN/C3 HT51 Bearing Typical Application Areas
The 6213-2ZN/C3 HT51 is a versatile component suited for a wide range of machinery and equipment, including:
- Electric Motors and Generators: For supporting shafts and handling radial loads.
- Industrial Gearboxes: Where reliable performance and axial location are key.
- Material Handling Equipment: Such as conveyor pulleys and rollers.
- Agricultural Machinery: Ideal for environments with high levels of dust and debris.
- Pumps and Compressors: Providing robust support for rotating assemblies.
