1216C3 Bearing Product Overview & Core Advantages
The 1216C3 is a metric double row angular contact ball bearing engineered for high-performance applications requiring robust support for combined loads. Its double row design provides exceptional high rigidity and stability, making it an ideal choice for precision machinery. This bearing is pre-lubricated and features an open design, optimized for handling significant radial loads while maintaining operational integrity. With its precision construction and C3 radial internal clearance, it is suited for scenarios demanding high reliability and dimensional accuracy.
1216C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1216 | Standard bearing series designation, indicating a bore diameter of 80mm and a specific cross-section. |
| C3 | Indicates a greater than normal radial internal clearance. This is beneficial for applications with thermal expansion or where interference fits are used. |
1216C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior high rigidity, enabling the bearing to effectively support combined loads (radial and axial) with minimal deflection.
- Optimized Cage Design: The Nylon cage contributes to smooth operation, reduced friction, and is suitable for high-speed applications, supporting the bearing's limiting speed of 6000 rpm.
- Precision & Durability: Manufactured from Chrome Steel for both rings and balls, ensuring high durability, wear resistance, and consistent performance under the specified temperature range (-30° to 110 °C).
- Pre-lubrication & Open Design: The bearing comes pre-lubricated, facilitating easy installation and initial operation. The open seal type allows for custom re-lubrication strategies if required by the application.
1216C3 Bearing Typical Application Areas
This double row angular contact ball bearing is commonly specified in:
- Industrial Gearboxes and Transmissions
- Electric Motors and Generators
- Material Handling Equipment
- Agricultural Machinery
- General Industrial Machinery requiring robust bearing support
