6215-2ZNR/C3GJN/JEM Bearing Product Overview & Core Advantages
The 6215-2ZNR/C3GJN/JEM is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This precision bearing features shielded protection and a snap ring groove, offering a robust solution for applications requiring high reliability and simplified mounting. Its design is optimized to handle significant radial loads while accommodating moderate axial loads, making it an ideal choice for compact assemblies where space is at a premium. Manufactured to ABEC 1 | ISO P0 tolerance standards with a C3 radial internal clearance, it ensures consistent performance and long service life.
6215-2ZNR/C3GJN/JEM Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| 2Z | Non-contact shields on both sides | Provides effective protection against contaminants while maintaining high-speed capability. |
| NR | Snap ring groove on the outer ring | Enables secure axial location and simplified bearing mounting within the housing. |
| C3 | Greater than normal radial internal clearance | Suitable for applications with thermal expansion or where interference fits are used. |
| GJN | Polyurea grease, medium viscosity oil | Offers excellent performance over a wide temperature range (-30°C to +120°C). |
6215-2ZNR/C3GJN/JEM Bearing Structural Features & Performance Benefits
This bearing's performance stems from its carefully engineered components and design features. The single row deep groove raceway geometry is fundamental for handling high radial dynamic load ratings of 15,152 lbf. The use of chrome steel for all critical components (rings, balls, and cage) ensures high strength, durability, and resistance to wear. The non-contact shields (2Z) effectively prevent the ingress of solid contaminants without significantly increasing friction, contributing to the high limiting speed of 4,800 rpm. The inclusion of a snap ring groove (NR) enhances design flexibility and reduces assembly costs by eliminating the need for complex housing shoulders. The pre-lubrication with GJN polyurea grease ensures immediate operation and long-term, maintenance-free performance within its specified temperature range.
