1208 Bearing Product Overview & Core Advantages
The 1208 is a metric double row ball bearing engineered for high performance in demanding applications. Its double row design provides superior rigidity and enables it to accommodate significant radial loads. Manufactured with precision tolerances and constructed from high-grade chrome steel, this bearing is built for reliability and long service life. The open seal type and pre-lubrication make it a versatile choice for a wide range of industrial machinery.
1208 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1208 | Standard designation for a double row deep groove ball bearing with a 40mm bore and 80mm outside diameter. |
| Open | No integral seals or shields, allowing for higher speeds and easier re-lubrication. |
| Cylindrical Bore | Standard bore design for a secure fit on a shaft. |
| CN Radial Clearance | Standard normal radial internal clearance, suitable for most common operating conditions. |
1208 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides a robust and rigid support system, significantly increasing its radial dynamic load rating (4478 lbf) compared to single row equivalents.
- Optimized for Speed: The combination of an open design and a lightweight nylon cage allows for a high limiting speed of 11,000 rpm, making it suitable for high-speed applications.
- Precision & Durability: Components made from chrome steel offer excellent wear resistance and fatigue life. Tight dimensional tolerances ensure consistent performance and ease of installation.
- Versatile Operation: Pre-lubricated and capable of operating within a temperature range of -30°C to 110°C, this bearing is ready for use in various environments.
1208 Bearing Typical Application Areas
The 1208 double row ball bearing is ideal for applications requiring high radial load capacity and rigidity in a compact envelope. Common uses include:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment
- Agricultural Machinery
- Pumps and Compressors
