6403-2RS1/C3 Bearing Product Overview & Core Advantages
The 6403-2RS1/C3 is a sealed single row deep groove ball bearing engineered for robust performance in demanding applications. Its primary advantage lies in its ability to efficiently handle radial loads while offering operational reliability. The bearing features integral contact seals (2RS1) for excellent contamination protection and is supplied with a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. This combination delivers a compact, long-lasting, and maintenance-friendly solution for a wide range of industrial machinery.
6403-2RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6403 | Standard bearing series designation indicating a metric single row deep groove ball bearing with a 17mm bore, 62mm OD, and 17mm width. | Defines the core bearing dimensions and type. |
| 2RS1 | Designates two (2) integral contact seals, one on each side, made of NBR rubber. | Provides superior protection against contaminants like dust and moisture, extending bearing service life. |
| C3 | Indicates a radial internal clearance greater than the Normal (CN) group. | Accommodates thermal expansion in the shaft or housing, and is ideal for applications with tight interference fits, preventing premature failure. |
6403-2RS1/C3 Bearing Structural Features & Performance Benefits
Deep Groove Raceway & Single Row Design: The optimized raceway geometry allows for smooth operation and high limiting speeds (up to 12,000 rpm), while effectively supporting radial loads.
Robust Construction: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing ensures high strength, durability, and consistent performance under load.
Integrated Sealing (2RS1): The NBR rubber contact seals on both sides effectively retain lubrication and exclude harmful contaminants. This design significantly enhances reliability in dirty or humid environments, contributing to a maintenance-free operational lifespan.
C3 Internal Clearance: This specific clearance group provides operational stability in applications prone to thermal growth or where press fits reduce the internal clearance, ensuring optimal performance and preventing seizure.
6403-2RS1/C3 Bearing Typical Application Areas
The 6403-2RS1/C3 is a versatile component suited for various industrial sectors requiring reliable rotational motion and contamination resistance. Key applications include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Components (e.g., alternators, idlers)
