1314KC3 Bearing Product Overview & Core Advantages
The 1314KC3 is a metric double row angular contact ball bearing engineered for high-performance applications requiring exceptional rigidity and the ability to handle combined loads. Featuring a tapered bore (1:12) for precise interference fits, this bearing is designed to support significant radial loads while offering high operational accuracy. Its construction, complete with a C3 radial internal clearance and factory-applied lubrication, makes it a robust and reliable choice for demanding industrial environments.
1314KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 1314 | Standard bearing series designation, indicating the core dimensions: 70mm bore, 150mm OD, 35mm width. |
| K | Denotes a tapered bore with a 1:12 ratio, enabling a secure and precise mounting on adapter sleeves or withdrawal sleeves. |
| C3 | Indicates a greater than normal radial internal clearance. This is optimal for applications with expected thermal expansion or where interference fits are used. |
1314KC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior stiffness and enables the bearing to accommodate substantial radial dynamic loads (16,672 lbf) and static loads (6,188 lbf).
- Tapered Bore Design: The 1:12 tapered bore ensures a tight and secure fit on a shaft, minimizing slippage and maintaining positional accuracy under high torque and vibration.
- Optimized for Demanding Conditions: With a stainless steel cage and a C3 clearance, this bearing is pre-conditioned for applications involving thermal gradients and heavy loads, contributing to stable performance.
- Ready for Operation: The bearing is supplied lubricated from the factory, facilitating immediate installation and initial operation within its specified temperature range of -30°C to 110°C.
1314KC3 Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for heavy-duty machinery and precision equipment, including:
- Industrial Gearboxes and power transmission systems
- Vibrating Screens and other material handling equipment
- Agricultural Machinery such as tractor transmissions
- Pump and Compressor shafts
- Paper and Steel Mill machinery
