6306-2ZNRJEM Bearing Product Overview & Core Advantages
The 6306-2ZNRJEM is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This metric bearing excels at handling primarily radial loads while offering robust performance. Its key advantages include the convenience of shielded construction for contaminant protection and a snap ring on the outer ring for simplified axial location and secure mounting, making it an ideal choice for applications requiring high reliability and ease of installation.
6306-2ZNRJEM Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Benefit |
|---|---|---|
| 6306 | Basic Bearing Series & Size | Denotes a medium-duty, single row deep groove ball bearing with a 30mm bore, 72mm OD, and 19mm width. |
| 2Z | Non-Contact Shields on Both Sides | Provides effective protection against contamination while maintaining a high limiting speed due to low friction. |
| NR | Snap Ring Groove on Outer Ring | Facilitates secure axial location within a housing, simplifying assembly and reducing the need for complex housing designs. |
| JEM | Japanese/International Manufacturer Designation | Indicates standard manufacturing specifications and quality control. |
6306-2ZNRJEM Bearing Structural Features & Performance Benefits
Optimized Deep Groove Raceway: The geometry of the raceways is engineered for smooth operation and efficient radial load support.
Shielded Protection: The non-contact 2Z shields retain the factory-applied lubrication and protect the internal components from dust and debris, enhancing operational life without a significant impact on speed capability.
Snap Ring Locating Feature: The outer ring snap ring groove (NR) provides a positive axial locating surface, increasing mounting rigidity and stability in the housing.
High-Quality Materials: Constructed entirely from chrome steel for rings, balls, and cage, ensuring high strength, durability, and consistent performance across the specified temperature range of -30°C to 120°C.
Standard Precision: Manufactured to ABEC 1 | ISO P0 tolerance class and standard CN radial internal clearance, guaranteeing reliable and predictable performance for general industrial applications.
