1208C3 Bearing Product Overview & Core Advantages
The 1208C3 is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and reliable performance under combined loads. Featuring an open design with precision bearing dimensions (40mm bore × 80mm OD × 18mm width), this bearing delivers exceptional stability and can accommodate significant radial loads while managing moderate axial loads in both directions. Its optimized internal geometry and C3 radial internal clearance make it suitable for applications with thermal expansion requirements or where increased operational flexibility is needed.
1208C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Impact |
|---|---|---|
| 1208 | Standard size designation: 40mm bore, 80mm OD | Standardized bearing dimensions for interchangeability |
| C3 | Radial internal clearance greater than normal | Accommodates thermal expansion, reduces preload risk |
| Open | No seals or shields (as per specification) | Enables high-speed operation and custom lubrication |
1208C3 Bearing Structural Features & Performance Benefits
Double Row Construction: The double row angular contact ball bearing design provides high rigidity and superior moment load capacity compared to single row bearings, making it ideal for applications requiring precise shaft positioning.
Enhanced Load Capacity: With a dynamic load rating of 4478 lbf and static load rating of 1564 lbf, this bearing effectively handles combined loads while maintaining operational stability.
High-Speed Capability: The nylon cage ensures smooth operation at limiting speeds up to 11,000 rpm, reducing friction and enabling efficient high-speed bearing performance.
Precision Engineering: Manufactured from chrome steel for both rings and balls, the bearing offers consistent performance across a temperature range of -30°C to 110°C with maintained dimensional stability.
1208C3 Bearing Typical Application Areas
- Industrial Gearboxes: Provides reliable support for transmission shafts under combined loads
- Electric Motors: Suitable for medium-duty motor applications requiring high rigidity
- Material Handling Equipment: Handles radial loads in conveyor systems and pulley assemblies
