6206-ZN/C3 Bearing Product Overview & Core Advantages
The 6206-ZN/C3 is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. This metric bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a high limiting speed of 11,000 rpm and a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. The combination of a shielded design (ZN) and a snap ring groove on the outer ring provides effective contamination protection and secure axial location, ensuring high operational reliability and simplified installation.
6206-ZN/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6206 | Standard bearing series designation, indicating a single row deep groove ball bearing with a 30mm bore and 62mm outside diameter. |
| Z | Denotes a shield on one side of the bearing. |
| N | Indicates a snap ring groove on the outer ring, enabling secure axial positioning within a housing. |
| C3 | Specifies a greater than normal radial internal clearance. This is critical for applications with expected temperature variations or where press fits reduce internal clearance. |
6206-ZN/C3 Bearing Structural Features & Performance Benefits
Shielded Design: The non-contact steel shield (Z) effectively retains lubrication and excludes larger contaminants, enhancing bearing life without significantly increasing friction or temperature.
High-Speed Capability: Manufactured to ABEC 1 | ISO P0 tolerance class with precision-ground chrome steel components, this bearing achieves a high limiting speed for its size, making it ideal for electric motors and spindles.
Robust Load Capacity: The deep groove raceway and chrome steel construction provide a high dynamic load rating of 4384 lbf, ensuring durability under significant radial loads.
Axial Location & Simplified Assembly: The snap ring groove (N) on the outer ring allows for easy and secure mounting, reducing the complexity and cost of the housing design.
Optimized Internal Clearance: The C3 clearance is engineered to prevent preload and seizure in applications prone to thermal expansion, such as in motor end-shields or gearboxes.
6206-ZN/C3 Bearing Typical Application Areas
The 6206-ZN/C3 is widely used across various industries due to its balanced performance characteristics. Key application areas include:
- Electric Motors & Generators: For shaft support in small to medium-sized industrial motors, benefiting from its high-speed capability and shielded protection.
- Gearboxes & Transmissions: Ideal for supporting gears and shafts where thermal growth is a factor, thanks to the C3 clearance.
- Pumps & Compressors: Used in fluid handling equipment where radial loads are predominant and contamination resistance is required.
- Material Handling Equipment: Conveyor pulleys and rollers utilize this bearing for its robust construction and ease of installation with the snap ring groove.
- Agricultural Machinery: Provides reliable performance in demanding environments found in farm equipment.
