1312-K C/3 Bearing Product Overview & Core Advantages
The 1312-K C/3 is a double row angular contact ball bearing designed for applications requiring high rigidity and precise operation. This precision bearing features a tapered bore (1:12) for secure mounting on adapter sleeves or withdrawal sleeves, ensuring accurate positioning and reliable performance. Its double row design enables it to accommodate significant combined loads—both radial and axial—simultaneously, making it an ideal choice for robust machinery. Pre-lubricated and featuring a nylon cage, it is engineered for smooth, high-speed operation and long service life in demanding industrial environments.
1312-K C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1312-K | Basic bearing designation. The "K" suffix indicates a tapered bore with a 1:12 ratio. |
| C/3 | Specifies the radial internal clearance group. "C3" denotes a clearance greater than normal (CN), suitable for applications with thermal expansion or interference fits. |
1312-K C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction provide exceptional stiffness, enabling the bearing to handle high radial dynamic load ratings and moderate axial loads from both directions.
- Precision Tapered Bore: The 1:12 tapered bore allows for precise axial positioning and a secure, interference fit on a shaft when used with an adapter sleeve, minimizing slippage and vibration.
- Optimized High-Speed Performance: The lightweight nylon cage ensures stable guidance of the balls at high rotational speeds, contributing to a high limiting speed and reduced friction.
- Pre-Lubricated & Ready-to-Use: The bearing is factory-filled with lubricant, providing immediate protection and reducing initial maintenance requirements. The open design allows for re-lubrication in service if needed.
- Standard Internal Clearance: The C3 radial internal clearance is selected to accommodate thermal expansion in the shaft-bearing system, preventing preload and ensuring smooth operation under varying temperature conditions.
1312-K C/3 Bearing Typical Application Areas
This double row angular contact ball bearing is widely used in heavy-duty industrial equipment where high rigidity and reliability are paramount. Key applications include:
- Industrial Gearboxes and power transmission systems
- Vibrating Screens and other material handling equipment
- Agricultural Machinery such as tractor transmissions
- Pump and Compressor shafts
- Heavy-duty Electric Motor applications
