1312C3 Bearing Product Overview & Core Advantages
The 1312C3 is a double row angular contact ball bearing engineered for applications requiring high load capacity and robust performance. This precision bearing is designed to accommodate significant combined loads, including radial and axial forces in both directions, within a compact bearing size. Its open design, pre-lubricated state, and optimized internal geometry make it an ideal solution for machinery demanding high reliability and operational stability.
1312C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1312 | Standard bearing series designation, indicating the basic dimensions: 60mm bore, 130mm OD, 31mm width. |
| C3 | Specifies a greater radial internal clearance than the standard C0 group. This is crucial for applications involving thermal expansion, high-speed operation, or where interference fits are used, preventing premature failure due to excessive preload. |
1312C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior rigidity and enables the bearing to support high radial dynamic load ratings of 13,162 lbf and radial static load ratings of 4,950 lbf. This makes it exceptionally capable of handling demanding combined loads.
Optimized for Performance: The use of a Nylon cage contributes to smooth operation, reduced friction, and is suitable for high-speed applications, supporting a limiting speed of 6,300 rpm. The C3 radial internal clearance ensures optimal performance under a wide range of operating temperatures and conditions.
Durable Construction: Manufactured from high-grade Chrome Steel for both rings and balls, this bearing offers excellent wear resistance and long service life. It comes pre-lubricated for immediate use and operates effectively within a temperature range of -30°C to 110°C.
1312C3 Bearing Typical Application Areas
This versatile bearing is commonly specified in a variety of industrial sectors, including:
- Electric Motors and Generators
- Industrial Gearboxes and Transmission Systems
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring robust and reliable shaft support
