1310KC3 Bearing Product Overview & Core Advantages
The 1310KC3 is a double row angular contact ball bearing designed for demanding industrial applications requiring high rigidity and precision. This metric bearing features a tapered bore (1:12) and is pre-lubricated for immediate use. Its double row design enables it to support significant combined loads, including substantial radial forces and bidirectional axial loads, making it an exceptionally robust and high rigidity solution. With a C3 radial internal clearance, it is optimized for applications with thermal expansion considerations, ensuring reliable performance under varying operational temperatures.
1310KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1310 | Standard bearing designation indicating bore diameter (50 mm) and size series. |
| K | Denotes a tapered bore with a 1:12 ratio, facilitating secure and precise mounting on adapter sleeves. |
| C3 | Indicates a greater radial internal clearance than normal (C0), suitable for applications with elevated operating temperatures or where fit interference generates heat. |
1310KC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior stiffness, effectively handling heavy combined loads and moment loads that would challenge single row designs.
- Precision Tapered Bore: The 1:12 tapered bore ensures a tight, slip-free fit on a shaft when used with an adapter sleeve, crucial for maintaining positional accuracy in high-torque applications.
- Optimized for Thermal Expansion: The C3 clearance allows for thermal expansion of the inner ring during operation, preventing preload and potential bearing seizure, thereby enhancing service life.
- Lightweight & Durable Cage: The Nylon cage offers excellent strength-to-weight ratio, contributing to smooth operation at the limiting speed and reduced friction.
- Pre-lubricated & Ready-to-Install: Factory-applied lubrication ensures immediate operation and reduces initial setup time.
1310KC3 Bearing Typical Application Areas
This bearing is engineered for robust machinery and precision systems, including:
- Industrial Gearboxes and power transmission systems
- Vibrating Screens and other material handling equipment
- Agricultural Machinery such as tractor transmissions
- Pump and Compressor shafts
- Electric Motor applications requiring a tapered bore fit
