6220/HC5C4HS1VK1761 Bearing Product Overview & Core Advantages
The 6220/HC5C4HS1VK1761 is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. Its open design facilitates high-speed operation, while the use of Silicon Nitride (Si3N4) ceramic balls significantly reduces friction, heat generation, and wear. This bearing is characterized by its high radial dynamic load capacity and is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring reliable and precise operation. It is an ideal solution for applications requiring a combination of high speed, lightweight components, and extended service life.
6220/HC5C4HS1VK1761 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6220 | Standard bearing series designation, indicating a metric deep groove ball bearing with a 100mm bore, 180mm OD, and 34mm width. |
| HC5 | Indicates the use of Hybrid Ceramic construction, specifically Silicon Nitride (Si3N4) balls. |
| C4 | Specifies a greater than normal radial internal clearance, suitable for applications with significant thermal expansion or where a heavy interference fit is used. |
| HS1 | Denotes a special heat-stabilized cage (Chrome Steel), enhancing dimensional stability at high operating temperatures. |
| VK1761 | A manufacturer's internal designation for a specific bearing variant or production batch. |
6220/HC5C4HS1VK1761 Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of steel rings and Silicon Nitride balls provides superior performance, including higher limiting speed, reduced weight, electrical insulation, and longer service life compared to all-steel bearings.
- High-Speed Capability: The open seal type minimizes friction, and the ceramic balls' lower density reduces centrifugal forces, allowing for a high limiting speed of 3,600 rpm.
- Thermal Stability: The heat-stabilized steel cage (HS1) ensures consistent performance and dimensional integrity across the wide operating temperature range of -30°C to 200°C.
- Optimized Internal Clearance: The C4 radial clearance accommodates thermal expansion in high-speed or high-temperature environments, preventing premature failure due to preload.
- High Load Capacity: Engineered to withstand a high radial dynamic load rating of 27,427 lbf, making it suitable for applications with significant radial forces.
6220/HC5C4HS1VK1761 Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications across various industries, including:
- High-Speed Spindles in machining centers and routers
- Electric Motors and generators, especially in variable frequency drive (VFD) applications
- Turbochargers and other high-RPM automotive components
- Aerospace auxiliary systems and instrumentation
- Medical Equipment such as dental handpieces and centrifuges
