6204 TN9/C3 Bearing Product Overview & Core Advantages
The 6204 TN9/C3 is a single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. Engineered to primarily support radial loads, this bearing features an open design that facilitates high-speed operation. Its key advantages include a high limiting speed and a generous radial internal clearance (C3), making it exceptionally suitable for applications where thermal expansion is a consideration. Manufactured with precision to ABEC 1 | ISO P0 tolerance standards, it delivers reliable and consistent performance, ensuring operational longevity and reduced downtime.
6204 TN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6204 | Standard bearing series designation, indicating a single row deep groove ball bearing with a 20mm bore, 47mm OD, and 14mm width. |
| TN9 | Specifies a glass fiber reinforced polyamide (Nylon) cage. This cage design is lightweight and contributes to lower friction, enabling higher rotational speeds and smooth operation. |
| C3 | Indicates a greater than normal radial internal clearance. This is critical for applications with expected thermal expansion, preventing preload and ensuring optimal performance under varying operating temperatures. |
6204 TN9/C3 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of the open seal type and the lightweight, robust TN9 nylon cage minimizes friction and allows for a high limiting speed of 15,000 rpm, making it an excellent choice for high-speed applications.
- Optimized Load Capacity: As a deep groove ball bearing, it is primarily designed to carry significant radial loads. The precision-ground chrome steel rings and balls provide high dynamic (2878 lbf) and static (1495 lbf) load ratings for reliable operation.
- Thermal Stability: The specified C3 clearance provides extra space between the rolling elements and raceways. This accommodates shaft and housing fits and differential thermal expansion, preventing binding and maintaining smooth rotation.
- Versatile Application Range: With a temperature range of -30°C to 120°C and no pre-applied lubrication (open design), it offers flexibility for use in various environments and allows for the application of specialized lubricants as required by the application.
6204 TN9/C3 Bearing Typical Application Areas
