6220/HC5C4S1VK1761 Bearing Product Overview & Core Advantages
The 6220/HC5C4S1VK1761 is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. This precision bearing is distinguished by its use of Silicon Nitride (Si3N4) ceramic balls, which provide superior speed capabilities, reduced friction, and extended service life compared to standard steel ball bearings. Its open design allows for versatile lubrication options, while the C4 radial internal clearance makes it suitable for applications with significant thermal expansion. This bearing is designed to handle primarily radial loads with high efficiency and reliability.

6220/HC5C4S1VK1761 Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and Silicon Nitride balls significantly reduces friction and heat generation, enabling higher limiting speeds (3,600 rpm) and providing electrical insulation properties.
- High-Temperature Capability: Featuring a stabilized cage and ring material, this bearing operates reliably across a wide temperature range from -30°C to 200°C.
- Optimized Internal Clearance: The C4 radial clearance accommodates differential thermal expansion between the shaft and housing, preventing preload and ensuring smooth operation in varying thermal conditions.
- Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class, ensuring consistent performance and reliable operation in general precision applications.
6220/HC5C4S1VK1761 Bearing Typical Application Areas
- Electric Motors & Generators: Ideal for high-speed spindle motors and generator applications where ceramic hybrid bearings reduce electrical arcing damage.
- Industrial Pumps & Compressors: Suitable for pump shafts and compressor systems requiring reliable performance under radial loads.
- Agricultural Machinery: Used in various agricultural equipment where contamination resistance and durability are essential.
- Material Handling Equipment: Applied in conveyor systems and other material handling machinery requiring robust bearing performance.
