6215-2ZNR/C3GJN Bearing Product Overview & Core Advantages
The 6215-2ZNR/C3GJN is a single row deep groove ball bearing engineered for robust performance in demanding applications. This shielded bearing features a snap ring groove on its outer ring for secure axial location within a housing. Its C3 radial internal clearance makes it suitable for applications with thermal expansion or where interference fits are used. Designed to handle primarily radial loads, it offers high reliability and long service life, making it an excellent choice for general industrial machinery requiring a pre-lubricated, shielded, and easily mounted component.
6215-2ZNR/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| 6215 | Basic designation: 75mm bore, 130mm OD, 25mm width. | Standard bearing dimensions for interchangeability. |
| 2Z | Non-contact shields on both sides. | Effective contamination protection with minimal friction increase. |
| NR | Snap ring groove on the outer ring. | Simplifies axial location and housing design. |
| C3 | Greater than normal radial internal clearance. | Accommodates thermal expansion and interference fits, preventing preload issues. |
| GJN | Pre-lubricated with a specific lithium soap base grease. | Provides maintenance-free operation for the bearing's initial service life. |
6215-2ZNR/C3GJN Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The deep groove raceway and high-quality chrome steel construction enable efficient handling of radial dynamic loads up to 15,152 lbf and radial static loads up to 10,858 lbf.
Integrated Sealing and Location: The combination of 2Z shields and the NR snap ring groove creates a unitized solution. This design protects the bearing from contaminants and simplifies installation by providing a positive axial location, enhancing overall operational reliability.
Enhanced Operational Range: The C3 clearance is a critical feature for applications subject to temperature variations, ensuring consistent performance without binding. The pre-lubrication (GJN) supports operation up to the limiting speed of 4,800 rpm across a wide temperature range of -30°C to 120°C.
