6202NR/C3 Bearing Product Overview & Core Advantages
The 6202NR/C3 is a single row deep groove ball bearing engineered for high-performance industrial applications. This metric bearing features a snap ring groove on its outer ring for secure axial positioning and simplified installation. With its C3 radial internal clearance, it is specifically designed to accommodate thermal expansion in applications with elevated operating temperatures or where interference fits are used. The open design allows for custom lubrication schemes, while its precision ABEC 1 | ISO P0 tolerance ensures reliable operation and long service life in demanding conditions.
6202NR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6202 | Standard deep groove ball bearing series with 15mm bore, 35mm OD |
| NR | Snap ring groove on outer ring for axial positioning and retention |
| C3 | Greater radial internal clearance than normal for thermal expansion compensation |
6202NR/C3 Bearing Structural Features & Performance Benefits
Snap Ring Design: The integrated snap ring groove provides reliable axial location, eliminating the need for additional housing shoulders and reducing assembly complexity.
Optimized Internal Clearance: The C3 clearance accommodates thermal expansion in high-temperature applications and interference fits, preventing premature bearing failure due to excessive preload.
High-Quality Materials: Constructed entirely from chrome steel for rings, balls, and cage, ensuring consistent performance, high durability, and excellent wear resistance.
Radial Load Capacity: With a dynamic load rating of 1812 lbf and static load rating of 843 lbf, this bearing delivers reliable performance under significant radial loads.
High-Speed Capability: The limiting speed of 20,000 rpm makes it suitable for high-speed applications when properly lubricated and maintained.
