1320 KM Bearing Product Overview & Core Advantages
The 1320 KM metric ball bearing is a double row angular contact ball bearing engineered for demanding industrial applications requiring high load capacity and robust performance. This precision bearing is designed to accommodate significant combined loads, including radial and bidirectional axial loads, within a single, compact unit. Manufactured from high-grade chrome steel and featuring a lightweight nylon cage, it delivers exceptional durability and reliable operation. Its open design, pre-lubricated for immediate use, makes it an ideal choice for applications prioritizing high rigidity and dependable service life.
1320 KM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 1320 | Standard bearing series designation, indicating the bearing dimensions (100mm bore, 215mm OD, 47mm width). | Defines the core geometry and interchangeability. |
| KM | Indicates a specific internal design and tolerance class. | Ensures consistent performance and fit for precision assemblies. |
| Open (Construction) | No integral seals or shields. | Allows for optimal heat dissipation and custom lubrication regimes, suitable for high-speed applications. |
1320 KM Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior high rigidity, enabling the bearing to handle substantial radial dynamic load ratings of 32,175 lbf and combined loads effectively, making it suitable for applications with complex loading conditions.
- Optimized High-Speed Performance: The lightweight nylon cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 4,000 rpm. The open design facilitates efficient lubrication management for sustained high-speed operation.
- Precision & Durability: Components made from chrome steel offer high hardness and wear resistance. The precise bearing dimensions and tight tolerances ensure reliable performance in precision machinery.
- Ready-to-Install: The bearing is pre-lubricated, simplifying installation and providing immediate protection during the initial run-in period.
1320 KM Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for a wide range of industrial machinery, including:
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (conveyors, pulleys)
- Medium-Duty Pumps and Compressors
- Agricultural Machinery
- General Industrial Machinery requiring robust support for combined loads
