6209-2RS1/C3HT Bearing Product Overview & Core Advantages
The 6209-2RS1/C3 is a single row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing excels at handling primarily radial loads and offers reliable operation due to its sealed construction. Its key advantages include a generous C3 radial internal clearance for thermal expansion in high-speed or high-temperature environments, and high-quality chrome steel construction for durability. The combination of a sealed design and a standard ABEC 1 | ISO P0 tolerance class makes it a versatile and cost-effective solution for a wide range of industrial machinery.
Model Code Breakdown
- 6209: Standard designation for a single row deep groove ball bearing with a 45mm bore and 85mm outside diameter.
- 2RS1: Indicates the bearing is fitted with two rubber contact seals (RS) on both sides. The "1" suffix denotes a specific seal design, providing effective protection against contaminants and retaining lubricant.
- C3: Specifies a greater radial internal clearance than the standard C0 group. This is critical for applications where thermal expansion of the shaft or housing is expected, preventing pre-load and ensuring smooth operation.
6209-2RS1/C3HT Bearing Structural Features & Performance Benefits
Sealed for Protection and Longevity: The 2RS1 rubber contact seals effectively shield the internal components from dust, moisture, and other contaminants. This design also retains the factory-applied grease, contributing to a maintenance-free service life in many applications and enhancing operational reliability.
Optimized Internal Clearance: The C3 radial clearance is a key performance feature. It accommodates rapid temperature fluctuations and interference fits, reducing friction and the risk of seizure, which is vital for maintaining performance under varying operational conditions.
Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers a high dynamic load rating of 7351 lbf and a static load rating of 4564 lbf, ensuring dependable performance under significant radial loads.
Balanced Performance: With a limiting speed of 7,700 rpm and a wide operating temperature range from -30°C to 120°C, this bearing is suited for a broad spectrum of industrial applications requiring a balance of speed capability and environmental resilience.
6209-2RS1/C3HT Bearing Typical Application Areas
The 6209-2RS1/C3 is a workhorse component found in numerous industrial sectors. Its sealed and robust design makes it ideal for:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- Pumps and Fans
- General machinery where contamination protection and reliable performance are paramount.
