1310 KC3 Bearing Product Overview & Core Advantages
The 1310 KC3 is a metric double row angular contact ball bearing engineered for applications requiring exceptional rigidity and the capacity to handle combined loads. Its double row design provides superior radial load capacity while effectively managing bidirectional axial loads. Featuring a C3 radial internal clearance and a tapered bore (1:12), this bearing is optimized for precision mounting on adapter sleeves or withdrawal sleeves, making it ideal for high-reliability industrial applications where precise shaft positioning is critical.
1310 KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1310 | Standard bearing series designation, indicating the bearing dimensions (50mm bore, 110mm OD, 27mm width). |
| K | Denotes a tapered bore with a 1:12 ratio, facilitating precise axial adjustment and secure mounting. |
| C3 | Specifies a greater than normal radial internal clearance. This is crucial for applications with thermal expansion or where interference fits are used, preventing preload and ensuring optimal performance. |
1310 KC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides significantly greater radial stiffness compared to single row bearings and is designed to support substantial combined loads (radial and bidirectional axial forces).
- Precision Tapered Bore: The 1:12 tapered bore allows for precise axial play adjustment during mounting on an adapter sleeve, ensuring optimal bearing performance and alignment.
- Optimized Cage & Speed: The nylon cage contributes to low friction, lower operating temperatures, and enables a high limiting speed of 8,000 rpm, making it suitable for high-speed applications.
- Robust Material & Lubrication: Manufactured from chrome steel for both rings and balls, the bearing offers high durability and fatigue resistance. It comes pre-lubricated for immediate operation.
1310 KC3 Bearing Typical Application Areas
This double row angular contact ball bearing is widely used in demanding industrial machinery, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
