1315 KC3 Bearing Product Overview & Core Advantages
The 1315 KC3 is a metric double row angular contact ball bearing engineered for demanding applications requiring high radial load capacity and rigidity. Its double row design provides superior stability and stiffness compared to single row bearings, making it ideal for supporting combined loads. Featuring a tapered bore (1:12) for precise mounting and a C3 radial internal clearance for optimal performance under operational thermal expansion, this bearing is a robust solution for high-reliability machinery.
1315 KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1315 | Standard bearing series designation, indicating the core dimensions (75mm bore, 160mm OD, 37mm width). |
| K | Denotes a tapered bore with a 1:12 ratio, allowing for precise axial positioning and secure interference fits on adapter sleeves or withdrawal sleeves. |
| C3 | Specifies a greater than normal radial internal clearance. This is essential for applications where thermal expansion is a factor, preventing preload and potential bearing seizure. |
1315 KC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides significantly higher radial stiffness and can support substantial radial loads (Dynamic: 17,842 lbf / Static: 6,750 lbf), ensuring stable operation under heavy loads.
- Precision Tapered Bore: The 1:12 tapered bore facilitates accurate and secure mounting on a shaft, minimizing runout and enhancing overall system precision.
- Optimized for Operational Conditions: The specified C3 clearance accommodates shaft expansion and housing contraction in high-temperature environments, maintaining performance and extending service life.
- High-Speed Capability: The nylon cage contributes to lower friction and allows for a high limiting speed of 5,600 rpm, suitable for various industrial drives.
- Material Integrity: Manufactured from chrome steel for rings and balls, ensuring high durability, wear resistance, and a long operational lifespan within a temperature range of -30°C to 110°C.
1315 KC3 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring robust support and high rigidity, including:
- 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 industrial fans and blowers.
