6209-2RS1/C3 GJN Bearing Product Overview & Core Advantages
The 6209-2RS1/C3 GJN is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. This sealed bearing is designed to handle primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a generous C3 radial internal clearance for thermal expansion management in high-temperature operations, and integrated rubber seals (2RS1) for superior contamination protection and long service life without re-lubrication. The combination of high-grade chrome steel construction and precision ABEC 1 tolerances ensures reliable operation and extended bearing service life.
6209-2RS1/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6209 | Standard deep groove ball bearing series with 45mm bore, 85mm OD, 19mm width. | Standardized dimensions for easy interchangeability. |
| 2RS1 | Contact rubber seals on both sides. | Effective protection against contaminants and moisture retention; pre-lubricated for life. |
| C3 | Radial internal clearance greater than Normal (CN) group. | Accommodates shaft expansion under high-speed or high-temperature conditions, preventing preload and failure. |
| GJN | Standard polyurea grease filling. | Provides excellent lubrication over the specified temperature range (-30°C to 120°C) and contributes to the limiting speed of 7,700 rpm. |
6209-2RS1/C3 GJN Bearing Structural Features & Performance Benefits
- Robust Single-Row Design: The deep groove raceway and continuous shoulder design enable efficient handling of radial dynamic load ratings up to 7351 lbf and static load ratings of 4564 lbf.
- Superior Sealing Solution: The 2RS1 contact seals provide an effective barrier against dust, dirt, and moisture, significantly extending bearing life in contaminated environments and making it a maintenance-free solution.
- Optimized Internal Clearance: The C3 clearance is critical for applications with expected thermal gradients, ensuring stable operation and preventing premature failure due to thermal expansion.
- High-Speed Capability: The combination of a precision chrome steel cage, optimized geometry, and high-performance GJN grease enables a high limiting speed of 7,700 rpm.
- Material Integrity: Manufactured entirely from high-carbon chromium steel, all bearing components (rings, balls, cage) offer high hardness, wear resistance, and durability.
6209-2RS1/C3 GJN Bearing Typical Application Areas
This versatile bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmission Systems
- Material Handling Equipment such as Conveyors
