6021-2RS2/C4S1GJN Bearing Product Overview & Core Advantages
The 6021-2RS2/C4S1GJN is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. Engineered with sealed construction and manufactured to ABEC 1 | ISO P0 precision standards, this bearing delivers reliable operation and long service life. Its key advantage lies in its ability to efficiently handle radial loads, making it an ideal component for machinery requiring consistent performance under standard operating conditions. The combination of chrome steel components and optimized internal geometry ensures high durability and stable operation across a wide temperature range from -30°C to 200°C.
6021-2RS2/C4S1GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6021 | Basic bearing designation (105mm bore, 160mm OD, 26mm width) |
| 2RS2 | Double rubber seals on both sides for superior contamination protection |
| C4 | Greater than normal radial internal clearance for thermal expansion applications |
| S1GJN | Special designation for specific manufacturing process and material treatment |
6021-2RS2/C4S1GJN Bearing Structural Features & Performance Benefits
Sealed Protection System: The double rubber seals (2RS2) provide excellent protection against contaminants while retaining lubrication, significantly extending bearing service life in harsh environments.
Optimized Internal Clearance: The C4 radial clearance accommodates thermal expansion in applications with significant temperature variations, preventing premature failure due to excessive preload.
Superior Material Construction: Manufactured from chrome steel for rings, balls, and cage, ensuring consistent mechanical properties, high wear resistance, and reliable performance under radial dynamic loads up to 16,254 lbf.
Precision Engineering: Built to ABEC 1 | ISO P0 tolerance class with tight dimensional control (bore tolerance: -0.02mm to 0), providing smooth operation and precise rotational accuracy.
6021-2RS2/C4S1GJN Bearing Typical Application Areas
- Industrial Electric Motors and generators requiring reliable radial support
- Material Handling Equipment including conveyor systems and pulley assemblies
- Agricultural Machinery such as tractor components and harvesting equipment
- Industrial Pumps and Compressors where sealed protection is essential
- General Industrial Machinery operating in contaminated environments
- Ventilation Systems and fan assemblies requiring long-term maintenance-free operation
