6202-2ZNR/C3GJN Bearing Product Overview & Core Advantages
The 6202-2ZNR/C3GJN is a single row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing excels in handling radial loads and offers high operational reliability. Its key advantages include the integrated snap ring on the outer ring for secure axial location, shielded construction for contaminant protection, and a C3 radial internal clearance suitable for applications with thermal expansion or interference fits. This combination makes it an ideal choice for compact assemblies requiring high reliability and simplified installation.
6202-2ZNR/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| 2Z | Non-Contact Shields (Both Sides) | Provides effective contamination protection while maintaining low friction and high-speed capability |
| NR | Snap Ring Groove | Enables secure axial positioning in housings, eliminating the need for complex housing shoulders |
| C3 | Greater than Normal Radial Clearance | Accommodates thermal expansion and interference fits, ideal for industrial applications |
| GJN | Lubrication: None | Requires external lubrication, offering flexibility in lubricant selection for specific operating conditions |
6202-2ZNR/C3GJN Bearing Structural Features & Performance Benefits
Optimized Bearing Design: The single row deep groove raceway geometry ensures smooth operation and efficient radial load distribution across all rolling elements.
Enhanced Sealing Performance: The 2Z non-contact shields provide reliable protection against contaminants while maintaining low operating torque, contributing to the limiting speed of 20,000 rpm.
Simplified Installation: The integrated snap ring groove (NR) allows for secure axial positioning without additional components, reducing assembly complexity and cost.
Thermal Stability: The C3 radial clearance accommodates thermal expansion in demanding applications, ensuring consistent performance across the operating temperature range of -30°C to 120°C.
Material Excellence: Manufactured from chrome steel for both rings and balls, providing excellent wear resistance and durability under dynamic load capacity of 1,812 lbf.
