6204 TN9/C4HLHT23 Bearing Product Overview & Core Advantages
The 6204 TN9/C4HLHT23 is a single row deep groove ball bearing engineered for superior performance in demanding applications. This precision bearing is characterized by its high radial load capacity and optimized internal geometry. A key feature is its C4 radial internal clearance, making it exceptionally suitable for applications with thermal expansion or where interference fits are used. The lightweight Nylon cage (TN9 designation) ensures smooth operation at high speeds, contributing to its excellent limiting speed and low noise levels. Manufactured to ABEC 1 | ISO P0 tolerance standards, it guarantees reliable and consistent operation.
6204 TN9/C4HLHT23 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6204 TN9/C4HLHT23 provides detailed technical specifications:
- 6204: Standard designation for a single row deep groove ball bearing with a 20mm bore, 47mm OD, and 14mm width.
- TN9: Indicates the cage material and design. "T" signifies a fiberglass-reinforced polyamide (Nylon) cage, and "9" denotes a specific, optimized cage design for high-speed performance and reduced friction.
- C4: Specifies a greater than normal radial internal clearance. This is critical for accommodating shaft expansion in high-temperature environments or heavy interference fits, preventing premature bearing failure.
- HLHT23: This suffix combination refers to a specific, high-temperature, rust-inhibiting grease. However, the provided specification states "Lubrication: None," indicating this bearing is supplied without grease. Please verify the required lubrication for your specific application.
6204 TN9/C4HLHT23 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The TN9 Nylon cage is lightweight and possesses excellent sliding properties, which reduces centrifugal forces and friction, allowing for a high limiting speed of 15,000 rpm.
- Optimized Load Handling: The deep groove raceway and high-quality chrome steel construction provide a high radial dynamic load rating of 2878 lbf and a radial static load rating of 1495 lbf, ensuring durability under significant stress.
- Thermal & Fit Adaptability: The C4 radial clearance is a critical feature that provides operational stability in applications prone to thermal expansion or where tight shaft fits are necessary, preventing internal preload and overheating.
- Precision & Consistency: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing ensures reliable running accuracy, low vibration, and consistent performance in a wide temperature range from -30°C to 120°C.
6204 TN9/C4HLHT23 Bearing Typical Application Areas
This bearing is ideally suited for a variety of industrial applications requiring high speed, reliability, and adaptability to thermal conditions. Common uses include:
- Electric Motors and small machinery spindles
- Industrial Fans and blowers
- Power Tools
- Pump and compressor assemblies
- Agricultural machinery and material handling equipment
