1318 C/3 Bearing Product Overview & Core Advantages
The 1318 C/3 is a double row angular contact ball bearing designed for applications requiring high precision and exceptional load capacity. This metric bearing features an open design and is engineered to accommodate significant combined loads, including substantial radial forces and moderate axial loads in both directions. Its robust construction ensures high rigidity and stable performance, making it an ideal choice for demanding industrial environments where reliability is paramount. The bearing comes pre-lubricated for immediate use and features optimized internal geometry for smooth operation.
1318 C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1318 | Standard bearing series designation, indicating the basic size and type. |
| C | Denotes a specific internal design and contact angle optimized for combined loads. |
| 3 | Indicates the Radial Internal Clearance group is C3, which is greater than normal clearance for applications with thermal expansion or specific fit requirements. |
1318 C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction and optimized raceway geometry provide superior stiffness and enable the bearing to support high radial dynamic load ratings of 26,325 lbf and significant combined loads.
- Precision Engineering: Manufactured from high-grade Chrome Steel for both rings and balls, ensuring dimensional stability and long service life under heavy loads.
- Optimized Cage Design: The Stainless Steel cage ensures precise ball guidance, reduces friction, and contributes to stable operation at the specified limiting speed.
- Standard Internal Clearance: The C3 radial internal clearance is suited for applications where interference fits or operational heat generation are factors, preventing preload and ensuring smooth running.
- Ready-to-Install: The bearing is pre-lubricated, facilitating immediate installation and initial operation without additional greasing.
1318 C/3 Bearing Typical Application Areas
The 1318 C/3 is widely used in heavy-duty industrial machinery and precision equipment, including:
- Gearboxes and power transmission systems
- Industrial Pumps and compressors
- Material handling equipment, such as conveyor pulleys
- Medium-duty machine tool components
- Agricultural and construction machinery
