1320-K-M-C3 Bearing Product Overview & Core Advantages
The 1320-K-M-C3 is a metric double row angular contact ball bearing engineered for superior performance in demanding applications. Featuring a tapered bore (1:12) and C3 radial internal clearance, it is designed to accommodate combined radial and axial loads efficiently. Its double row ball construction provides exceptional rigidity and load-carrying capacity, making it an ideal choice for high-precision machinery requiring reliable, long-lasting operation. The bearing comes pre-lubricated and is manufactured from high-grade chrome steel for enhanced durability.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 1320 | Basic bearing designation | Defines the standard bearing size series. |
| K | Tapered bore (1:12) | Enables precise interference fit on tapered shafts for secure mounting. |
| M | Brass cage | Provides high strength and excellent guidance for high-speed applications. |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with high operating temperatures or heavy loads. |
1320-K-M-C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design significantly increases the bearing's rigidity and its ability to handle substantial combined loads (radial and axial loads from both directions). This makes it exceptionally stable under complex loading conditions.
Optimized for High Speeds: The brass cage (M) ensures smooth ball guidance and reduces friction, contributing to the bearing's capability to operate at limiting speeds up to 4,000 rpm.
Pre-Configured Internal Clearance: The C3 clearance is a critical feature for applications prone to thermal expansion, preventing premature failure by ensuring optimal internal play under operational heat and load.
Robust Material Construction: Manufactured from chrome steel rings and balls, the bearing offers high wear resistance and a long operational lifespan, even in challenging environments.
1320-K-M-C3 Bearing Typical Application Areas
The 1320-K-M-C3 is ideally suited for heavy-duty industrial machinery where high rigidity and the ability to handle combined loads are paramount. Key application areas include:
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural and Construction Machinery
- Electric Motors requiring a secure tapered bore fit
