6308-2RS1/C4 Bearing Product Overview & Core Advantages
The 6308-2RS1/C4 is a single row deep groove ball bearing designed for robust performance in demanding applications. This sealed bearing excels at handling significant radial loads while also accommodating moderate axial loads in both directions. Its construction ensures reliable operation, making it suitable for a wide range of industrial machinery. A key feature is its C4 radial internal clearance, which is optimized for applications involving thermal expansion or where fits result in a reduction of internal clearance, ensuring consistent performance under varying operational conditions.
6308-2RS1/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6308 | Standard bearing series designation, indicating a medium duty, single row deep groove ball bearing with a 40mm bore. |
| 2RS1 | Signifies contact seals on both sides of the bearing. The "RS1" type seals provide effective protection against contamination and retain lubricant. |
| C4 | Indicates a greater than normal radial internal clearance. This is critical for applications with shaft or housing fits that reduce clearance or where operational temperatures are elevated. |
6308-2RS1/C4 Bearing Structural Features & Performance Benefits
Robust Sealed Construction: The 2RS1 contact seals are a primary structural feature, effectively shielding the internal components from contaminants like dust and moisture. This significantly enhances bearing life and reliability, making it a maintenance-free solution for many applications as it comes pre-greased from the factory.
Optimized Internal Clearance: The C4 clearance is a critical performance feature. It accommodates thermal expansion and interference fits, preventing excessive preload and subsequent overheating, which can lead to premature failure. This ensures stable operation across the specified temperature range.
High-Quality Material: Manufactured entirely from chrome steel for the rings, balls, and cage, this bearing offers high strength, durability, and resistance to wear, contributing to its dynamic and static load ratings.
6308-2RS1/C4 Bearing Typical Application Areas
The 6308-2RS1/C4 is versatile and finds use in numerous sectors, including:
- Electric Motors and Generators: For supporting shafts and handling radial loads.
- Industrial Gearboxes and Transmissions: Where reliable, sealed performance is required.
- Material Handling Equipment: Such as conveyor pulleys and rollers.
- Agricultural Machinery: Providing durable bearing solutions in dusty environments.
- General Industrial Machinery: Pumps, fans, and blowers that require a robust, sealed deep groove ball bearing.
