6203-2RSH/C3VT376 Bearing Product Overview & Core Advantages
The 6203-2RSH/C3 is a single row deep groove ball bearing designed for exceptional reliability and performance in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while offering robust construction and extended service life. The bearing features integral contact seals (2RS) for superior 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, high-value solution for a wide range of industrial machinery.
Model Code Breakdown
- 6203: Standard designation for a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width.
- 2RS: Indicates the bearing is fitted with rubber contact seals on both sides. These seals provide excellent protection against dust and moisture ingress.
- H: Signifies that the seals are made from Hydrogenated Nitrile Butadiene Rubber (HNBR), offering enhanced resistance to high temperatures, oils, and chemicals compared to standard NBR.
- C3: Denotes a greater radial internal clearance than the standard C0 group. This is ideal for applications involving elevated operational temperatures or tight shaft fits to prevent binding.
6203-2RSH/C3VT376 Bearing Structural Features & Performance Benefits
Robust Sealing for Longevity: The double-sided HNBR contact seals (2RSH) effectively shield the bearing's internal components from contaminants, significantly extending lubricant life and overall bearing service life, even in harsh environments.
Optimized Internal Clearance: The C3 clearance provides operational stability in applications prone to thermal expansion, preventing excessive preload and associated heat generation, which contributes to reliable performance.
High-Quality Construction: Manufactured from chrome steel for both rings and balls, this bearing ensures high strength and durability. The ABEC 1 (ISO P0) tolerance class guarantees consistent quality and performance for general industrial applications.
High-Speed Capability: With a limiting speed of 17,000 rpm, this bearing is well-suited for a variety of high-speed applications, supported by its precision-ground components.
6203-2RSH/C3VT376 Bearing Typical Application Areas
The 6203-2RSH/C3 is a versatile component widely used across numerous industries, including:
- Electric Motors: Ideal for main shafts in small to medium-sized industrial and automotive electric motors.
- Pumps and Compressors: Provides reliable support in fluid handling equipment.
- Material Handling Equipment: Used in conveyor rollers, pulleys, and gearboxes.
- Agricultural Machinery: Suitable for applications in tractors, harvesters, and other farm equipment.
- General Industrial Machinery: A standard choice for fans, blowers, and transmission systems.
