6208-2RS1NR/C3 Bearing Product Overview & Core Advantages
The 6208-2RS1NR/C3 is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This sealed bearing is distinguished by its ability to handle significant radial loads and moderate axial loads in both directions. Its compact design, combined with a snap ring groove on the outer ring, facilitates secure mounting and saves space within assemblies. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable and precise operation, making it an ideal choice for applications requiring high reliability and long service life.
6208-2RS1NR/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6208 | Standard designation for a single row deep groove ball bearing with a 40mm bore, 80mm OD, and 18mm width. | Defines the core bearing dimensions and type. |
| 2RS1 | Contact seals on both sides of the bearing. | Provides superior protection against contaminants and retains lubricant, enhancing bearing life. |
| NR | Snap ring groove on the outer ring. | Enables axial location and secure fitting in housings, simplifying assembly and disassembly. |
| C3 | Greater than normal radial internal clearance. | Ideal for applications with expected thermal expansion or where interference fits are used, preventing preload and ensuring smooth operation. |
6208-2RS1NR/C3 Bearing Structural Features & Performance Benefits
The performance of the 6208-2RS1NR/C3 is a direct result of its robust construction. The single row deep groove raceway geometry is optimized for high radial load capacity, while also accommodating axial loads. The use of high-grade chrome steel for all bearing components (rings, balls, and cage) ensures high strength, durability, and resistance to wear. The contact seals (2RS1) are a critical feature, effectively shielding the internal components from dust, moisture, and other abrasive particles. This, combined with the C3 clearance, makes the bearing exceptionally resilient in applications prone to thermal fluctuations or requiring tight fits, preventing binding and ensuring consistent performance. The inclusion of a snap ring groove (NR) adds to its versatility, providing a reliable and cost-effective method for axial positioning within a housing.
6208-2RS1NR/C3 Bearing Typical Application Areas
The 6208-2RS1NR/C3 is a versatile component found in a wide array of industrial machinery. Its combination of load capacity, sealed construction, and secure mounting features makes it particularly suitable for:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., Conveyors)
- Agricultural Machinery
- Construction Equipment
