6203-2RSH Bearing Product Overview & Core Advantages
The 6203-2RSH is a metric single row deep groove ball bearing designed for exceptional reliability in demanding applications. This sealed bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its compact design, featuring a 17 mm bore and 40 mm outside diameter, makes it an ideal choice for space-constrained assemblies requiring high precision and consistent performance. Manufactured with chrome steel rings and balls, it delivers robust durability and long service life.
6203-2RSH Bearing Model Code Explained, Specifications & Naming Convention
The model number 6203-2RSH provides detailed technical specifications through its suffix codes:
- 6203: Basic designation for a single row deep groove ball bearing with a 17 mm bore and 40 mm outside diameter.
- 2RSH: Indicates the bearing features two-sided contact seals made of NBR (Nitrile Butadiene Rubber). The "H" signifies a higher temperature resistance compared to standard NBR seals, enhancing protection against contamination and moisture ingress.
6203-2RSH Bearing Structural Features & Performance Benefits
Superior Sealing & Contamination Resistance: The 2RSH contact seals provide an effective barrier against dust, dirt, and moisture, making this bearing suitable for harsh environments. This contributes to its maintenance-free characteristic and extended operational life.
High Precision & Rigidity: Manufactured to a P6 tolerance class, this bearing ensures precise running accuracy and minimal vibration, which is critical for high-speed applications. The stainless steel cage provides excellent guidance and stability for the balls, contributing to smooth operation and high limiting speed (12,000 rpm).
Optimized Load Capacity & Lubrication: With a dynamic load rating of 2237 lbf and a static load rating of 1068 lbf, it offers reliable performance under significant radial stresses. The bearing is pre-lubricated with high-quality grease, ensuring immediate readiness for installation and smooth operation across its specified temperature range of -30°C to 120°C.
6203-2RSH Bearing Typical Application Areas
The 6203-2RSH is widely used across various industries due to its versatility and reliability. Common applications include:
- Electric Motors and Small Gearboxes
- Industrial Pumps and Compressors
- Agricultural Machinery and Conveyor Systems
- Automotive Components such as alternators and idler pulleys
