1319 K Bearing Product Overview & Core Advantages
The 1319 K is a double row angular contact ball bearing designed for applications demanding high rigidity and reliable performance under combined loads. Its metric bearing dimensions (95 mm bore, 200 mm OD, 45 mm width) provide a compact and robust solution. Featuring an open design and precision Nylon cage, this bearing is optimized for high rotational speeds while maintaining dimensional stability. Its construction enables it to accommodate significant radial loads and bidirectional axial loads simultaneously, making it an ideal choice for high-precision machinery and heavy-duty industrial equipment where space constraints and performance reliability are critical.
1319 K Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| K | Indicates a tapered bore with a taper of 1:12. This design facilitates precise axial adjustment and secure mounting on adapter sleeves or withdrawal sleeves, allowing for optimal internal clearance control. |
| (No Seal Suffix) | The bearing is an Open type, meaning it is supplied without integral seals or shields. This configuration is suitable for applications where external sealing is provided or where the operating environment allows, enabling higher limiting speeds and facilitating custom lubrication regimes. |
1319 K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust Chrome Steel construction provide exceptional rigidity, enabling the bearing to withstand heavy radial dynamic loads (29,925 lbf) and static loads (11,475 lbf) as well as acting axial loads from both directions.
- Optimized High-Speed Performance: The lightweight and durable Nylon cage ensures smooth operation and guides the balls effectively, contributing to a high limiting speed of 4,300 rpm. The low friction of the cage material is crucial for high-speed applications.
- Precision Tapered Bore (K-designation): The tapered bore allows for precise micro-adjustment of the bearing's internal clearance during mounting. This feature is vital for achieving optimal preload, reducing vibration, and enhancing overall system accuracy and service life.
- Wide Operating Range: Manufactured from high-grade Chrome Steel, the bearing operates reliably within a temperature range of -30°C to 110°C, ensuring performance stability across diverse industrial environments.
1319 K Bearing Typical Application Areas
This bearing is engineered for demanding sectors that require robust support and high-speed capability. Key applications include:
- Industrial Gearboxes and Transmissions
- Vibrating Screens and Material Handling Equipment
- Agricultural Machinery (e.g., tractor gearboxes, harvesters)
- Pump and Compressor Systems
- Paper and Pulp Processing Machinery
