6210-2RS1NR/GJN Bearing Product Overview & Core Advantages
The 6210-2RS1NR/GJN is a single row deep groove ball bearing engineered for high reliability in demanding applications. Its core advantages stem from a combination of sealed construction and an outer ring snap ring, offering robust protection against contamination and simplified axial location within a housing. This bearing is designed to primarily handle radial loads and is characterized by its low maintenance design and consistent performance within a standard ABEC 1 (ISO P0) tolerance class, making it a versatile and cost-effective solution for a wide range of industrial machinery.
6210-2RS1NR/GJN Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6210 | Basic designation for a single row deep groove ball bearing with a 50mm bore, 90mm OD, and 20mm width. | Defines the core bearing dimensions and type. |
| 2RS1 | Contact seals on both sides of the bearing. | Provides effective protection against contaminants and retains lubricant, enhancing service life. |
| NR | Outer ring has a snap ring groove and a snap ring is fitted. | Simplifies axial location and securing of the bearing in the housing, reducing assembly complexity. |
| GJN | Specifies a standard radial internal clearance group (CN). | Ensures consistent performance under normal operating conditions and fits. |
6210-2RS1NR/GJN Bearing Structural Features & Performance Benefits
Sealed & Protected Design: The 2RS1 contact seals are a critical feature, effectively shielding the bearing's interior from dust, moisture, and other particulate contaminants. This design significantly extends the bearing's operational life by preventing premature failure and maintains performance integrity.
Integrated Mounting Solution: The snap ring (NR) on the outer ring eliminates the need for complex housing shoulders or separate locking devices. This feature provides a secure axial location, simplifies the assembly process, and reduces the overall cost of the surrounding structure.
Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers a substantial radial dynamic load rating of 7891 lbf and a static load rating of 5238 lbf. This ensures reliable performance under significant radial stresses.
Standardized Precision & Operation: Conforming to ABEC 1 (ISO P0) tolerance and CN clearance, this bearing delivers predictable and consistent running accuracy for general industrial applications. Its limiting speed of 7,100 rpm makes it suitable for a wide range of operational speeds.
6210-2RS1NR/GJN Bearing Typical Application Areas
The 6210-2RS1NR/GJN is ideally suited for applications requiring a reliable, pre-sealed, and easily mounted ball bearing. Its combination of features makes it a preferred choice in:
- Electric Motors and Gearboxes
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- Industrial Fans and Blowers
- Pumps and Compressors
- General Machinery where simplified housing design is beneficial
