6206/C3 GJN Bearing Product Overview & Core Advantages
The 6206/C3 GJN is a single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. As a metric bearing, it excels in handling primarily radial loads with high efficiency. Its key advantages include a C3 radial internal clearance, which accommodates thermal expansion in applications with high operating temperatures or heavy loads, ensuring reliable operation and extended service life. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers excellent cost-effectiveness for general-purpose machinery requiring dependable performance.
6206/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6206 | Basic Bearing Series & Size | Indicates a single row deep groove ball bearing with a 30mm bore, 62mm OD, and 16mm width. |
| /C3 | Radial Internal Clearance | Specifies a greater than normal clearance, ideal for applications with thermal expansion or where interference fits are used. |
| GJN | Lubrication Designation | Indicates the bearing is pre-lubricated with a specific, high-quality grease suitable for a wide temperature range. |
6206/C3 GJN Bearing Structural Features & Performance Benefits
Optimized for Versatility and Durability: The single row design with deep raceways provides high radial load capacity and moderate axial load capacity in both directions. All components, including the rings, balls, and pressed steel cage, are manufactured from high-grade chrome steel, ensuring high strength and resistance to wear. The C3 clearance is a critical feature that prevents pre-loading and seizure in applications prone to thermal expansion, making it a reliable choice for electric motors, gearboxes, and industrial fans. With a limiting speed of 11,000 rpm and pre-lubrication, it offers a long service interval and consistent performance.
6206/C3 GJN Bearing Typical Application Areas
This bearing is widely used across various industries due to its robust construction and versatile clearance. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring reliable ball bearing performance
