6418 Bearing Product Overview & Core Advantages
The 6418 is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. As a metric bearing with an open design, it is engineered to primarily handle high radial loads while also accommodating moderate axial loads in both directions. Its robust construction using high-grade chrome steel for rings and balls ensures durability and long service life. This bearing is characterized by its high radial dynamic load rating of 41,814 lbf and is manufactured to ABEC-1 precision tolerances, making it a reliable and cost-effective solution for a wide range of machinery.
6418 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation |
|---|---|
| 6418 | Standard designation for a single row deep groove ball bearing with a 90mm bore and 225mm outside diameter. |
| Open (No Seal/Shield suffix) | Indicates the bearing has no integrated seals or shields, allowing for higher limiting speeds and facilitating custom lubrication regimes. It is not pre-lubricated. |
| ABEC-1 | Specifies the tolerance class, denoting standard precision levels for bore, outside diameter, and width. |
| CN Clearance | Denotes standard radial internal clearance for normal operating conditions. |
6418 Bearing Structural Features & Performance Benefits
- High Load Capacity: The deep groove raceway and robust single row construction are optimized to support the high radial dynamic load rating of 41,814 lbf and a radial static load rating of 33,721 lbf, ensuring reliable operation under significant stress.
- Optimized for Speed: The open design and stainless steel cage contribute to a high limiting speed of 3,000 rpm, minimizing friction and heat generation.
- Precision and Stability: Manufactured to ABEC-1 tolerances, this bearing provides consistent running accuracy, which is crucial for reducing vibration and noise in applications.
- Material Integrity: Components made from chrome steel offer high hardness and wear resistance, while the stainless steel cage provides excellent corrosion resistance and strength.
- Flexible Lubrication: As an open bearing, it allows for the application of specialized lubricants tailored to specific operational needs, such as extreme temperatures within its range of -30°C to 110°C.
6418 Bearing Typical Application Areas
The 6418 deep groove ball bearing is versatile and finds use in numerous sectors, including:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (e.g., conveyor pulleys)
