6008-2ZNR Bearing Product Overview & Core Advantages
The 6008-2ZNR is a single row deep groove ball bearing engineered for exceptional reliability in demanding applications. This metric bearing features integral shielded protection and a snap ring groove on its outer ring, offering a compact and secure mounting solution. Its design is optimized to handle significant radial loads while maintaining smooth operation. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and is ideal for applications requiring a robust, pre-lubricated, and ready-to-install component.
6008-2ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Model Suffix | Technical Meaning | Advantage |
|---|---|---|
| 2Z | Non-contact shields on both sides | Provides effective protection against contamination while minimizing friction, contributing to the limiting speed of 10,000 rpm. |
| NR | Snap ring groove on the outer ring | Enables secure axial location within a housing without the need for complex housing shoulders, simplifying assembly and reducing total bearing dimensions and weight. |
6008-2ZNR Bearing Structural Features & Performance Benefits
- Robust Load Capacity: Constructed from hardened chrome steel for both rings and balls, this bearing delivers a high radial dynamic load rating of 3754 lbf and a radial static load rating of 2585 lbf, ensuring durability under substantial loads.
- Optimized for High-Speed Operation: The single row design with non-contact shields allows for a high limiting speed, making it suitable for applications requiring rapid rotation.
- Simplified Installation and Maintenance: The snap ring groove (NR) facilitates easy and secure mounting. The bearing comes pre-greased and shielded (2Z), making it a maintenance-free solution for the majority of its service life within the specified temperature range of -30°C to 120°C.
- Standardized Precision: Manufactured to ABEC 1 (ISO P0) tolerance class with CN group radial internal clearance, it guarantees reliable and predictable performance for general industrial use.
