1320KC3 Bearing Product Overview & Core Advantages
The 1320KC3 is a double row angular contact ball bearing engineered for demanding industrial applications requiring high load capacity and precision. This metric system bearing features a tapered bore (1:12) for secure shaft mounting and is designed to accommodate significant combined loads, including radial and axial forces. Its robust construction ensures high rigidity and reliable performance in high-precision machinery. Pre-lubricated for immediate use, it offers excellent operational readiness and longevity.
1320KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1320 | Basic bearing designation indicating the size series and bore diameter. |
| K | Denotes a tapered bore with a 1:12 ratio. |
| C3 | Specifies a greater radial internal clearance than normal, suitable for applications with thermal expansion or where interference fits are used. |
1320KC3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball construction provides superior stiffness and enables the bearing to handle high radial dynamic load ratings (32,175 lbf) and static load ratings (12,825 lbf). This design is optimal for applications with significant combined loads.
Precision & Material Quality: Manufactured from chrome steel for both rings and balls, and featuring a stainless steel cage, the bearing ensures high durability, corrosion resistance, and consistent performance. The C3 internal clearance accommodates thermal expansion in high-speed or high-temperature operations.
Mounting & Operational Efficiency: The tapered bore facilitates precise and secure mounting on adapter sleeves or withdrawal sleeves, ensuring optimal alignment and power transmission. The bearing is pre-lubricated, promoting smooth operation from startup and contributing to a long service life within its specified temperature range of -30°C to 110°C.
1320KC3 Bearing Typical Application Areas
The 1320KC3 is ideally suited for heavy-duty industrial machinery and precision equipment, including:
- Industrial Gearboxes and power transmission systems
- Vibrating Screens and material handling equipment
- Pumps and compressors
- Agricultural Machinery
- Mining and Construction Equipment
