6206-2RS1NR/C3 HT51 Bearing Product Overview & Core Advantages
The 6206-2RS1NR/C3 is a single row deep groove ball bearing engineered for high reliability and robust performance in demanding applications. This sealed bearing features a snap ring groove on its outer ring, enabling secure axial location within a housing. Its key advantages include the ability to accommodate significant radial loads and moderate axial loads in both directions. The combination of C3 radial internal clearance, sealed construction, and a snap ring makes it an ideal, compact solution for applications requiring simplified assembly, contamination protection, and stable operation under varying thermal conditions.
6206-2RS1NR/C3 HT51 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6206-2RS1NR/C3 provides a detailed technical specification. Below is a breakdown of its components:
- 6206: Basic model number denoting a single row deep groove ball bearing with a 30mm bore diameter.
- 2RS1: Designates that the bearing is sealed on both sides with contact rubber seals, providing effective protection against contaminants and retaining lubricant.
- NR: Indicates the bearing is fitted with a snap ring groove on its outer ring. This feature allows for simplified axial positioning and secure mounting within a housing.
- /C3: Specifies a greater than normal radial internal clearance. This is beneficial for applications with shaft or housing fits that cause a reduction in clearance, or where operational temperatures vary significantly.
6206-2RS1NR/C3 HT51 Bearing Structural Features & Performance Benefits
- Robust Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 4384 lbf, ensuring long service life under substantial radial loads.
- Effective Sealing & Contamination Resistance: The 2RS1 double-contact seals effectively shield the internal components from dust, moisture, and other contaminants, while also retaining the factory-applied grease, enhancing bearing longevity.
- Simplified Assembly and Axial Location: The integrated snap ring (NR) eliminates the need for complex housing shoulders or separate retaining components, reducing assembly time and cost while ensuring secure axial positioning.
- Operational Stability: The C3 clearance group provides operational stability in applications where thermal expansion is a factor, preventing premature failure due to excessive preload.
- Precision & Quality: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing offers consistent performance and high running accuracy for a wide range of industrial applications.
6206-2RS1NR/C3 HT51 Bearing Typical Application Areas
The 6206-2RS1NR/C3 is versatile and is commonly specified in:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (e.g., conveyor systems)
- Agricultural Machinery
