1320 K Bearing Product Overview & Core Advantages
The 1320 K is a double row deep groove ball bearing designed for applications requiring high radial load capacity and robust performance. This open-type bearing features a compact design that delivers exceptional rigidity and stability, making it ideal for demanding industrial environments. Its construction allows it to accommodate significant radial loads while maintaining smooth operation. Pre-lubricated for immediate use, it offers reliable performance right out of the box and operates effectively within a wide temperature range from -30°C to 110°C.
1320 K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1320 | Standard bearing series designation, indicating a metric double row deep groove ball bearing with a 100mm bore diameter. |
| K | Denotes a tapered bore (conicity 1:12). This facilitates precise axial adjustment and secure mounting on adapter sleeves or withdrawal sleeves. |
1320 K Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The double row ball construction significantly increases the radial dynamic load rating (32,175 lbf) and radial static load rating (12,825 lbf) compared to single row bearings. This provides superior support and minimizes deflection under heavy loads.
- Optimized Cage Design: The Nylon cage ensures quiet operation, reduced friction, and is suitable for the bearing's limiting speed of 4,000 rpm. It contributes to lower operating temperatures and enhanced high-speed performance.
- Tapered Bore Advantage: The K suffix indicates a tapered bore, which allows for precise internal clearance adjustment and a secure, interference fit when mounted with appropriate sleeves, eliminating creep and ensuring maximum power transmission.
- Material & Lubrication: Manufactured from high-grade Chrome Steel for both rings and balls, ensuring durability and long service life. The bearing is pre-lubricated, providing immediate protection and smooth running from startup.
1320 K Bearing Typical Application Areas
The 1320 K bearing is engineered for heavy-duty applications where high radial load capacity and secure mounting are paramount. Key industries and machinery include:
- Industrial Gearboxes and power transmission systems
- Vibrating Screens and other material handling equipment
- Agricultural Machinery such as tractors and harvesters
- Pump Systems requiring robust and reliable shaft support
- Mining and Construction Equipment
