6204-2ZNR Bearing Product Overview & Core Advantages
The 6204-2ZNR is a single row deep groove ball bearing engineered for high reliability in demanding applications. This shielded bearing features an integral snap ring on its outer ring, enabling simplified axial location within a housing. Its design excels at handling radial loads while offering robust performance across a wide temperature range. Pre-lubricated with grease and built with chrome steel components, it delivers long service life with minimal maintenance, making it an ideal compact bearing solution for industrial machinery.
6204-2ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6204 | Standard bearing series designation indicating a metric, single row deep groove ball bearing with a 20mm bore, 47mm OD, and 14mm width. | Defines the core bearing dimensions and type for interchangeability. |
| 2Z | Signifies that the bearing is equipped with shields on both sides. | Provides effective protection against contamination from solid particles, enhancing bearing life. |
| NR | Indicates the outer ring has a snap ring groove and a snap ring is fitted. | Allows for secure axial location in the housing, simplifying assembly and reducing the need for complex housing shoulders. |
6204-2ZNR Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The deep groove raceway and high-quality chrome steel construction enable it to carry significant radial dynamic load ratings of 3035 lbf, ensuring dependable performance under stress.
- Integrated Snap Ring Design: The fitted snap ring (52.7mm OD, 1.12mm width) provides a positive axial locating feature, which streamlines the design of the surrounding housing and improves assembly accuracy.
