6202-2ZNR Bearing Product Overview & Core Advantages
The 6202-2ZNR is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This precision bearing features integral shielded protection and a snap ring groove on its outer ring, enabling secure axial location within a housing. Engineered from high-grade chrome steel and pre-lubricated with grease, it offers reliable operation, high limiting speed, and robust radial load capacity. Its compact design and shielded construction make it an ideal, long-lasting solution for applications requiring minimal maintenance and high reliability.
6202-2ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| 2Z | Non-contact steel shields on both sides | Provides effective protection against contaminants while maintaining high-speed capability and low friction. |
| NR | Snap ring groove on the outer ring | Simplifies bearing axial location and housing design, reducing assembly costs and improving positional accuracy. |
6202-2ZNR Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from hardened chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 1812 lbf and a static load rating of 843 lbf, ensuring durability under significant radial loads.
- Enhanced Sealing & Contamination Resistance: The 2Z shields effectively retain grease and exclude larger particulate contaminants, contributing to a longer service life and reduced maintenance needs.
- Simplified Installation & Axial Location: The snap ring groove (NR) allows for secure axial positioning, preventing creep and simplifying the overall housing design. This is critical for maintaining precise bearing dimensions and alignment in the assembly.
- Optimized for High-Speed Operation: The combination of a low-friction stainless steel cage, precision-ground components, and effective sealing enables a high limiting speed of 22,000 rpm.
- Ready-to-Use & Maintenance-Friendly: Pre-lubricated with grease and featuring a standard CN radial internal clearance and P0 tolerance class, the bearing is ready for immediate installation, ensuring consistent performance right out of the box.
