6318/C3W64E Bearing Product Overview & Core Advantages
The 6318/C3W64E is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This metric bearing is characterized by its ability to accommodate high radial loads and moderate axial loads in both directions. A key feature is its C3 radial internal clearance, making it particularly suitable for applications involving thermal expansion or where interference fits are used. The integration of Soild Oil lubrication ensures long-term, maintenance-free operation, enhancing reliability and reducing total cost of ownership.
6318/C3W64E Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6318 | Standard bearing series designation, indicating a 90 mm bore, 190 mm OD, and 43 mm width. | Defines the core bearing dimensions for interchangeability and selection. |
| C3 | Specifies a greater than normal radial internal clearance. | Prevents bearing seizure in applications with high thermal gradients or tight fits, ensuring operational reliability. |
| W64E | Indicates the bearing is pre-lubricated with Soild Oil, a solid polymer-based lubricant. | Provides a maintenance-free, long-life solution. It is resistant to wash-out and can operate in a wide temperature range. |
6318/C3W64E Bearing Structural Features & Performance Benefits
Robust Construction for High Load Capacity: Manufactured from high-grade chrome steel for both rings, balls, and cage, this bearing delivers high strength and durability. The single row deep groove geometry is optimized to support significant radial dynamic load ratings of 32,148 lbf and radial static load ratings of 24,055 lbf.
Optimized for Stable Operation: The C3 clearance is a critical design feature that accommodates dimensional changes from heat or press-fitting, preventing preload and ensuring smooth running. The ABEC 1 | ISO P0 tolerance class guarantees consistent quality and performance for a wide range of industrial applications.
Maintenance-Free Longevity with Soild Oil: The W64E suffix signifies the bearing is filled with Soild Oil. This eliminates the need for re-lubrication, prevents lubricant leakage, and protects against contamination, making it ideal for sealed-for-life applications.
6318/C3W64E Bearing Typical Application Areas
The 6318/C3W64E is ideally suited for a variety of industrial machinery where reliability and minimal maintenance are paramount. Key sectors include:
- Electric Motors and Generators: Handles high speeds and radial loads in industrial motor applications.
- Material Handling Equipment: Used in conveyor pulleys and gearboxes subject to heavy loads.
- Industrial Fans and Blowers: The maintenance-free nature is advantageous in hard-to-reach or continuous operation environments.
- Agricultural Machinery: Withstands harsh conditions and shock loads in equipment such as tractors and harvesters.
- General Industrial Machinery: A versatile choice for pumps, compressors, and other machinery requiring a robust, pre-lubricated ball bearing.
