6418/C3 Bearing Product Overview & Core Advantages
The 6418/C3 is a single row deep groove ball bearing engineered for robust performance in demanding industrial applications. This open-type bearing is designed to primarily accommodate high radial loads, making it a fundamental and reliable component in various machinery. Its metric dimensions (90mm bore, 225mm OD, 54mm width) and construction from high-grade chrome steel ensure durability and consistent operation. A key feature is its specified C3 radial internal clearance, which makes it particularly suitable for applications involving thermal expansion or where interference fits are used, providing enhanced operational stability.
6418/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Advantage |
|---|---|---|
| 6418 | Standard designation for a single row deep groove ball bearing with a 90mm bore and 225mm outside diameter. | Indicates the bearing's size series and core dimensions, ensuring interchangeability. |
| /C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Provides extra clearance to accommodate thermal expansion from high operating speeds or tight interference fits, preventing premature failure due to excessive preload. |
6418/C3 Bearing Structural Features & Performance Benefits
The performance of the 6418/C3 is derived from its fundamental design and material selection:
- High Load Capacity: The single row deep groove construction and chrome steel components provide a high radial dynamic load rating of 41,814 lbf and a radial static load rating of 33,721 lbf, enabling it to handle significant radial forces.
- Optimized for Specific Conditions: The C3 clearance is a critical performance feature, ensuring reliable operation in applications prone to shaft and housing thermal expansion, thereby maintaining optimal performance and extending bearing life.
- Standard Precision & Versatility: Manufactured to ABEC 1 | ISO P0 tolerance class, it offers excellent value and reliable performance for a wide range of general industrial applications without the need for ultra-high precision.
- Broad Operating Range: With a temperature range of -30°C to 120°C, it is suitable for use in diverse environmental conditions.
