6210-2RS1NR/LHT64 Bearing Product Overview & Core Advantages
The 6210-2RS1NR/LHT64 is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This sealed bearing features an integral snap ring on its outer ring, facilitating simplified axial location within a housing. Its primary advantages include robust radial load capacity and long service life, enhanced by contact seals that effectively retain lubrication and exclude contaminants. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and is pre-lubricated with LHT64 grease for a wide operating temperature range, making it a compact and maintenance-friendly solution for a variety of industrial machinery.
Model Code Breakdown
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6210 | Standard designation for a single row deep groove ball bearing with a 50mm bore. | Defines the fundamental bearing dimensions and type. |
| 2RS1 | Designates two-sided contact seals made of NBR rubber. | Provides excellent protection against contamination and effective grease retention. |
| NR | Indicates a snap ring groove on the outer ring. | Simplifies axial location and reduces housing design complexity and cost. |
| LHT64 | Specifies the type of lithium-based grease used. | Ensures reliable performance across a broad temperature range from -30°C to 120°C. |
6210-2RS1NR/LHT64 Bearing Structural Features & Performance Benefits
The performance of the 6210-2RS1NR/LHT64 is derived from its specific construction. The single row deep groove raceway geometry is optimized for handling high radial loads, with a dynamic load rating of 7891 lbf. The use of a stamped steel cage ensures reliable ball guidance and contributes to a high limiting speed of 7,100 rpm. The contact seals (2RS1) are a critical feature, providing a superior barrier against dust and moisture compared to non-contact shields, thereby extending the bearing's operational life. The inclusion of the snap ring (NR) offers a distinct advantage for assembly, allowing for secure axial positioning without the need for complex housing shoulders or end caps. All components are manufactured from chrome steel, providing the necessary hardness and durability for long-term use.
6210-2RS1NR/LHT64 Bearing Typical Application Areas
This versatile and robust bearing is ideally suited for applications requiring reliable performance with minimal maintenance. Common uses include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Conveyor System Pulleys and Idlers
- Agricultural Machinery
- Material Handling Equipment
Its sealed and pre-lubricated design makes it particularly valuable in environments where re-lubrication is difficult or where contamination from dust, dirt, or moisture is a concern.
