6204-2RZTN9/C3VT162 Bearing Product Overview & Core Advantages
The 6204-2RZTN9/C3VT162 is a single row deep groove ball bearing designed for high reliability and performance in demanding applications. This sealed bearing excels at handling significant radial loads while also accommodating moderate axial loads in both directions. Its compact design, combined with a C3 radial internal clearance, makes it particularly suitable for applications where thermal expansion is a concern, ensuring stable operation across a wide temperature range. The bearing is pre-lubricated and sealed for life, offering a maintenance-free solution that enhances operational efficiency and reduces total cost of ownership.
6204-2RZTN9/C3VT162 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6204 | Basic bearing series designation, indicating a single row deep groove ball bearing with a 20mm bore, 47mm OD, and 14mm width. |
| 2RZ | Bearing is equipped with non-contact seals on both sides. The "2" indicates two seals, and "RZ" denotes low-friction, non-contact rubber seals that provide effective protection against contaminants while minimizing torque and heat generation. |
| TN9 | Indicates a glass fiber reinforced polyamide (Nylon) cage, design "TN9". This cage design is lightweight, promotes smooth operation at high speeds, and is compatible with a wide range of lubricants. |
| C3 | Specifies a greater than normal radial internal clearance. This is ideal for applications with expected thermal expansion, such as in electric motors, ensuring optimal performance and preventing premature failure due to excessive preload. |
| VT162 | Identifies the specific high-performance grease used for lubrication. This grease is selected to provide long-term lubrication, stable performance across the specified temperature range (-30°C to 120°C), and extended service life. |
6204-2RZTN9/C3VT162 Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The deep groove raceway geometry and high-quality chrome steel construction enable the bearing to support high radial dynamic load ratings (2878 lbf) and static loads (1495 lbf), making it robust for various industrial applications.
High-Speed Capability: The combination of the lightweight Nylon TN9 cage and the low-friction 2RZ non-contact seals allows for a high limiting speed of 15,000 rpm. This design minimizes centrifugal forces and frictional heat, which is critical for maintaining performance in high-speed operations.
Maintenance-Free Operation: The integrated seals (2RZ) and factory-applied VT162 grease create a sealed-for-life system. This eliminates the need for re-lubrication, protects against contamination, and ensures consistent performance, reducing maintenance downtime and costs.
Thermal Stability: The specified C3 radial internal clearance accommodates dimensional changes due to thermal expansion, preventing binding and ensuring smooth operation even under varying thermal conditions. This feature is vital for applications like electric motors and gearboxes.
6204-2RZTN9/C3VT162 Bearing Typical Application Areas
- Electric Motors: Ideal for main shafts and auxiliary drives in industrial motors, benefiting from the C3 clearance and sealed design.
- Industrial Gearboxes: Used in various gearbox stages where reliable radial load support and contamination protection are required.
- Pumps and Compressors: Suitable for handling radial loads in pump shafts and compressor assemblies, with the seals protecting against fluid and particulate ingress.
- Material Handling Equipment: Applied in conveyor rollers, pulleys, and other components demanding durability and minimal maintenance.
- Agricultural Machinery: Used in applications such as tractor accessories and implement drives, where sealed bearings are essential for operation in harsh, dusty environments.
