6304-2RSIN Bearing Product Overview & Core Advantages
The 6304-2RS1N is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This metric bearing features integral contact seals (2RS1) and a snap ring groove (N) on its outer ring, offering superior protection against contaminants and simplified axial location within a housing. Engineered to primarily handle radial loads, its deep groove raceway also accommodates moderate axial loads. Manufactured to ABEC 1 / ISO P0 tolerance standards, it provides a cost-effective solution for applications requiring robust performance, extended service life, and minimal maintenance.
6304-2RSIN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6304 | Standard deep groove ball bearing series with 20mm bore, 52mm OD, 15mm width. | Standardized dimensions for easy interchangeability and sourcing. |
| 2RS1 | Bearing with contact seals on both sides. | Provides excellent protection against dust, moisture, and other contaminants, retaining lubricant for maintenance-free operation. |
| N | Snap ring groove on the outer ring. | Facilitates secure axial positioning within a housing, simplifying design and assembly by eliminating the need for complex housing shoulders. |
6304-2RSIN Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS1 contact seals are molded from synthetic rubber and press firmly against the inner ring, creating an effective barrier that significantly extends bearing life in contaminated environments. This design is superior to non-contact shields for exclusion capability.
- Simplified Housing Design: The snap ring groove (N) allows for a cost-effective and compact housing design. A single snap ring can axially locate the bearing, reducing machining costs and assembly time.
- High-Grade Material & Construction: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing ensures high strength, durability, and consistent performance under the specified radial dynamic load rating of 3574 lbf and static load rating of 1765 lbf.
- Standardized Precision: Conforming to ABEC 1 / ISO P0 tolerance class and CN radial internal clearance, it delivers reliable, smooth, and quiet operation for a wide range of industrial applications.
