1317 KC3 Bearing Product Overview & Core Advantages
The 1317 KC3 is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This metric bearing features a tapered bore (1:12) for secure shaft mounting and is supplied pre-lubricated for immediate operation. Its double row design provides high rigidity and the ability to support significant combined loads (radial and axial) simultaneously. Manufactured from high-grade chrome steel and featuring a lightweight nylon cage, it is engineered for high-speed operation and reliable service in industrial machinery.
1317 KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1317 | Standard bearing designation indicating a tapered bore and specific bearing dimensions (85mm bore, 180mm OD). |
| K | Denotes a tapered bore with a 1:12 ratio, facilitating precise interference fit on the shaft. |
| C3 | Specifies a greater than normal radial internal clearance, suitable for applications with thermal expansion or where a tight fit is used. |
1317 KC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior stiffness, enabling it to handle heavy radial loads and moderate axial loads from both directions, making it ideal for applications with combined loads.
- Optimized High-Speed Performance: The lightweight nylon cage reduces centrifugal forces, lowers friction, and contributes to a high limiting speed of 4,800 rpm. The open design allows for efficient lubrication management.
- Precision Tapered Bore: The 1:12 tapered bore ensures a precise and secure fit on a tapered shaft adapter, minimizing slippage and maintaining concentricity under high torque.
- Robust Material Construction: Rings and balls made from chrome steel offer high fatigue resistance and durability, ensuring a long operational lifespan under demanding conditions.
1317 KC3 Bearing Typical Application Areas
This bearing is commonly specified in applications requiring robust support and high-speed capability. Key industries and equipment include:
- Electric Motors and Motorized Spindles
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Vibrating Screens and other material handling equipment
- Agricultural Machinery
