6220-2RS1/C3 Bearing Product Overview & Core Advantages
The 6220-2RS1/C3 is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. This sealed bearing excels in handling significant radial loads and moderate axial loads in both directions. Its key advantages include a high radial dynamic load rating of 27,427 lbf, reliable operation up to a limiting speed of 3,600 rpm, and a generous C3 radial internal clearance suitable for applications with thermal expansion or shaft misalignment. Manufactured from high-grade chrome steel and compliant with ROHS and REACH standards, it offers a dependable, long-service-life solution.
6220-2RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6220 | Basic bearing designation indicating a single row deep groove ball bearing with a 100 mm bore and 180 mm outside diameter. |
| -2RS1 | Signifies contact-type nitrile rubber (NBR) seals on both sides. This provides superior protection against contaminants and retains lubricant effectively. |
| /C3 | Indicates a greater than normal radial internal clearance. This is essential for applications involving thermal expansion, high speeds, or where fits may cause clearance reduction. |
6220-2RS1/C3 Bearing Structural Features & Performance Benefits
Robust Construction for High Load Capacity: The single row deep groove raceway geometry is optimized to support high radial loads. Combined with high-precision chrome steel balls and a chrome steel cage, this design ensures stable operation and a high dynamic load rating.
Enhanced Sealing for Reliability: The 2RS1 designation indicates two integral contact seals. These seals provide excellent defense against moisture, dust, and other contaminants, significantly extending the bearing's service life in harsh environments. The seals also effectively retain any subsequently applied lubricant.
Optimized Internal Clearance for Versatility: The C3 clearance group allows for axial displacement of the rings relative to each other, accommodating shaft misalignment and thermal expansion without inducing excessive preload, which can lead to overheating and premature failure.
Precision and Quality: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing provides consistent performance and dimensional accuracy for a wide range of general industrial applications.
6220-2RS1/C3 Bearing Typical Application Areas
- Electric Motors and Generators: A primary application due to its ability to handle radial loads at moderate speeds.
- Industrial Gearboxes and Transmissions: Used in various stages for supporting shafts and gears.
- Material Handling Equipment: Ideal for conveyor pulleys, rollers, and other components requiring reliable, sealed bearings.
- Agricultural Machinery: Suitable for applications in tractors, combines, and other equipment exposed to dusty conditions.
- Pumps and Compressors: Provides dependable performance in fluid handling equipment.
