6220 Bearing Product Overview & Core Advantages
The 6220 is a single row deep groove ball bearing designed for exceptional performance in a wide range of industrial applications. Engineered to primarily accommodate high radial loads, its fundamental design ensures smooth operation and long service life. Manufactured to ABEC-1 precision tolerances, this bearing offers a reliable and cost-effective solution where high precision is not the primary driver but consistent performance is critical. Its open design allows for versatile lubrication options to suit specific operational environments, making it a highly adaptable component for demanding machinery.
6220 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 62 | Series designation, indicating a medium width and a medium diameter series deep groove ball bearing. |
| 20 | Bore diameter code. For this metric bearing, 20 indicates a 100 mm bore diameter (20 x 5 = 100 mm). |
| (Open) | The absence of a seal or shield suffix indicates an open bearing, allowing for optimal lubrication flow and heat dissipation, but requiring an external sealing solution in contaminated environments. |
6220 Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The single row deep groove construction is optimized to carry significant radial loads (Dynamic: 27,427 lbf, Static: 2,093 lbf), making it suitable for heavy-duty applications.
- High-Speed Capability: With a limiting speed of 3,600 rpm, the bearing is capable of stable operation in high-velocity scenarios, supported by its precision-ground chrome steel rings and balls.
- Durable Cage Design: The stainless steel cage provides high strength and corrosion resistance, ensuring reliable ball guidance and structural integrity at high speeds.
- Standardized Precision: Conformance to ABEC-1 tolerance class and CN group radial internal clearance offers a balance of performance, interchangeability, and cost-effectiveness for general industrial use.
- Material Integrity: Components made from high-grade chrome steel offer excellent hardness and wear resistance, contributing to a long operational lifespan.
