1310-K C/3 Bearing Product Overview & Core Advantages
The 1310-K C/3 is a metric double row angular contact ball bearing designed for applications requiring high radial load capacity and precise shaft positioning. Featuring a 1:12 tapered bore for secure mounting and nylon cage construction, this bearing delivers exceptional rotational precision and smooth operation. Its double row design provides superior rigidity and stability compared to single row bearings, making it ideal for machinery where minimal deflection under load is critical. The bearing comes pre-lubricated and operates effectively within a wide temperature range of -30°C to 110°C.
1310-K C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1310-K | Basic bearing designation with tapered bore (1:12) |
| C/3 | Specifies CN radial internal clearance group (Normal clearance) |
1310-K C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides significantly higher radial stiffness than single row designs, enabling superior performance under substantial radial loads (Dynamic: 9810 lbf / Static: 3150 lbf).
- Precision Tapered Bore: The 1:12 taper ensures secure interference fit on tapered shaft seats, eliminating creep and maintaining precise shaft alignment under heavy loads and vibration.
- Optimized High-Speed Performance: The lightweight nylon cage reduces centrifugal forces, lowers friction, and enables smooth operation up to 8000 rpm, making it suitable for high-speed applications.
- Maintenance-Friendly Design: The open seal type allows for easy re-lubrication, while the factory-applied lubricant provides immediate operation readiness and protection during run-in periods.
- Premium Material Construction: Manufactured from chrome steel for both rings and balls, ensuring high durability, wear resistance, and consistent performance in demanding industrial environments.
1310-K C/3 Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
- Machine Tool Spindles requiring high precision and rigidity
- Material Handling Equipment such as conveyor pulleys
- Agricultural Machinery including tractor transmissions
- Pump and Compressor Systems demanding reliable bearing performance
- Electric Motors with tapered shaft configurations
