1319-KM C/3 Bearing Product Overview & Core Advantages
The 1319-KM C/3 is a double row angular contact ball bearing designed for applications requiring exceptional rigidity and the ability to handle combined loads. Its metric design features a tapered bore (1:12 ratio) for precise shaft mounting. This bearing is engineered to support significant radial loads while also accommodating axial loads in both directions, making it an ideal choice for high-precision machinery where stability and reliability are paramount. The open seal type and pre-lubrication ensure optimal performance in demanding industrial environments.
1319-KM C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1319 | Standard bearing series designation, indicating the bearing dimensions (95mm bore, 200mm OD, 45mm width). |
| KM | Indicates a tapered bore (1:12) and a withdrawal sleeve is used for mounting. |
| C | Specifies the radial internal clearance group. In this case, 'C' corresponds to the standard CN clearance group. |
| 3 | Denotes the cage type. The number '3' typically indicates a brass cage, which offers high strength and is suitable for high-speed applications. |
1319-KM C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior rigidity, enabling the bearing to handle substantial combined loads (radial and bidirectional axial loads) with minimal deflection.
- Precision Tapered Bore: The 1:12 tapered bore allows for precise interference fit on the shaft using an adapter sleeve, ensuring a secure and accurate mounting for critical applications.
- Optimized High-Speed Performance: The machined brass cage (Cage material) ensures stable ball guidance and low friction, contributing to a high limiting speed of 4,300 rpm.
- Superior Material Construction: Manufactured from chrome steel for both rings and balls, the bearing offers high durability, wear resistance, and a long operational lifespan.
- Standard Internal Clearance: The CN radial internal clearance is a standard fit for most industrial applications, providing a balance between operational temperature rise and running precision.
1319-KM C/3 Bearing Typical Application Areas
The 1319-KM C/3 is ideally suited for heavy-duty industrial machinery and precision equipment where high rigidity and reliable performance under combined loads are essential. Key application areas include:
- Industrial Gearboxes and power transmission systems
- Vibrating Screens and other material handling equipment
- Pump and Compressor shafts
- Paper Mill Machinery
