6202-2ZNR/C3 Bearing Product Overview & Core Advantages
The 6202-2ZNR/C3 is a single row deep groove ball bearing engineered for high-performance industrial applications. This shielded bearing features an integral snap ring on its outer ring, enabling secure axial location within a housing without requiring complex machining. Its C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used. Designed for radial loads with a dynamic load rating of 1812 lbf, this bearing offers reliable operation within a temperature range of -30°C to 120°C, making it an excellent choice for demanding environments.
6202-2ZNR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| 2Z | Non-contact shields on both sides | Provides effective contamination protection while maintaining high-speed capability |
| NR | Snap ring groove with snap ring | Enables secure axial positioning and simplifies housing design |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits, reducing operating temperature risks |
6202-2ZNR/C3 Bearing Structural Features & Performance Benefits
This bearing's construction delivers several key performance advantages:
- Enhanced Contamination Resistance: The dual non-contact shields (2Z) effectively exclude contaminants while minimizing friction, contributing to the limiting speed of 20,000 rpm.
- Simplified Installation & Positioning: The integrated snap ring (NR) provides reliable axial location, eliminating the need for complex housing shoulders and reducing assembly time.
- Optimized Clearance for Demanding Conditions: The C3 radial clearance accommodates thermal expansion in high-speed applications and compensates for interference fits, ensuring consistent performance under varying operating conditions.
- Robust Load Capacity: Manufactured from chrome steel throughout (rings, balls, and cage), the bearing delivers a radial dynamic load rating of 1812 lbf for extended service life in radial load applications.
6202-2ZNR/C3 Bearing Typical Application Areas
The 6202-2ZNR/C3 is widely used across various industries where reliable radial bearing performance with secure positioning is required:
- Electric Motors & Generators: Particularly in smaller industrial motors requiring shielded protection and secure housing location
- Gearboxes & Transmission Systems: Where snap ring positioning simplifies assembly and C3 clearance accommodates thermal changes
- Industrial Fans & Blowers: Benefiting from the contamination protection and high-speed capability
- Material Handling Equipment: Conveyor systems and pulley assemblies requiring reliable radial support
- Agricultural Machinery: Applications demanding robust performance in challenging environments
