6209-2RS1K/C3 Bearing Product Overview & Core Advantages
The 6209-2RS1K/C3 is a sealed deep groove ball bearing designed for robust performance in demanding industrial applications. As a single row bearing, it excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a generous C3 radial internal clearance for stable operation under thermal expansion, and integrated contact seals (2RS1) that provide superior protection against contaminants. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers reliable precision and is pre-lubricated for long service life, making it an excellent choice for applications requiring high reliability and minimal maintenance.
6209-2RS1K/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| 6209 | Standard deep groove ball bearing series with 45mm bore, 85mm OD | Standard dimensions for interchangeability |
| 2RS1 | Double-sided contact rubber seals | Effective contamination protection, retains lubrication |
| K | Tapered bore (1:12) | Facilitates precise mounting and dismounting |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion, ideal for high-temperature applications |
6209-2RS1K/C3 Bearing Structural Features & Performance Benefits
Optimized Sealing System: The double-contact rubber seals (2RS1) provide excellent protection against dust, moisture, and other contaminants while effectively retaining the factory-applied lubricant. This design significantly extends bearing service life in harsh environments.
Enhanced Thermal Stability: The C3 radial clearance is specifically engineered to accommodate shaft and housing expansion under operational temperature variations, preventing premature failure due to excessive preload and ensuring consistent performance.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class with chrome steel rings, balls, and cage, this bearing delivers reliable operation with minimal vibration and noise. The tapered bore (K-suffix) allows for precise axial positioning and secure mounting on adapter sleeves.
Robust Load Capacity: With a dynamic load rating of 7351 lbf and static load rating of 4564 lbf, this bearing handles significant radial loads while maintaining operational stability across its temperature range of -30°C to 120°C.
