1213C3 Bearing Product Overview & Core Advantages
The 1213C3 is a double row angular contact ball bearing designed for applications requiring high load capacity and operational stability. This precision bearing is engineered to accommodate significant combined loads, including radial and bidirectional axial loads, within a compact bearing dimensions envelope. Its open design, pre-lubricated state, and C3 radial internal clearance make it an ideal solution for arrangements where thermal expansion must be accommodated, ensuring reliable performance in demanding industrial environments.
1213C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1213 | Standard bearing designation indicating a double row angular contact ball bearing with a 65mm bore diameter. |
| C3 | Specifies a radial internal clearance greater than normal (C3 group). This is crucial for applications with expected thermal expansion or where fit-up conditions require extra internal space. |
1213C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides superior rigidity and enables the bearing to support high radial dynamic load ratings of 7898 lbf and significant axial loads from both directions simultaneously.
- Optimized for Thermal Expansion: The specified C3 radial internal clearance allows for dimensional changes due to operational heat, preventing preload and potential seizure, thereby enhancing service life.
- Lightweight & Efficient Operation: The use of a Nylon cage reduces weight and inertial forces, contributing to smoother operation and lower energy consumption. The bearing is pre-lubricated for immediate use.
- Material Integrity: Manufactured from Chrome Steel for both rings and balls, ensuring high durability, wear resistance, and consistent performance within a temperature range of -30°C to 110°C.
1213C3 Bearing Typical Application Areas
This bearing is well-suited for a variety of industrial machinery, including:
- Industrial gearboxes and transmissions
- Electric motors and generators
- Material handling equipment (conveyors, pulleys)
- Agricultural machinery
- General industrial machinery requiring robust support for combined loads
