6218-2RS1/C3WT Bearing Product Overview & Core Advantages
The 6218-2RS1/C3WT is a single row deep groove ball bearing designed for robust performance in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads while offering a sealed design for enhanced protection. This bearing features a generous C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides reliable and consistent operation, ensuring high reliability in industrial machinery.
6218-2RS1/C3WT Bearing Model Code Explained, Specifications & Naming Convention
- 6218: Basic designation indicating a single row deep groove ball bearing with a 90mm bore and 160mm outside diameter.
- -2RS1: Signifies that the bearing is equipped with two contact seals (one on each side), providing excellent protection against contamination and retaining lubricant.
- /C3: Denotes a greater than normal radial internal clearance, ideal for applications involving thermal expansion or heavy interference fits.
- WT: Indicates the bearing is supplied without lubrication, allowing for application-specific grease selection.
6218-2RS1/C3WT Bearing Structural Features & Performance Benefits
The 6218-2RS1/C3WT leverages a single row deep groove raceway design, optimized for high-capacity radial load support. The incorporation of contact seals (2RS1) provides a robust barrier against contaminants like dust and moisture, significantly extending service life and enabling use in harsh environments. The C3 clearance accommodates dimensional changes from heat or press-fits, preventing premature failure due to excessive preload. Constructed entirely from chrome steel, including the rings, balls, and cage, the bearing ensures high strength, durability, and consistent performance across its specified temperature range of -30°C to 120°C.
6218-2RS1/C3WT Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial applications where reliability and contamination protection are paramount. Common uses include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- Pumps and Compressors
