1320-KM C/3 Bearing Product Overview & Core Advantages
The 1320-KM C/3 is a double row angular contact ball bearing designed for high-performance industrial applications. This precision bearing features a tapered bore (1:12) for secure shaft mounting and is pre-lubricated for immediate operation. Its core advantage lies in its ability to handle significant combined loads—both radial and axial—while offering high rigidity due to its double row ball construction. This makes it an ideal solution for machinery requiring robust support and reliable, long-term performance.
1320-KM C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1320 | Standard bearing series designation. |
| K | Indicates a tapered bore with a 1:12 ratio. |
| M | Designates a brass cage. |
| C/3 | Specifies the radial internal clearance group, which is the standard CN clearance for normal operating conditions. |
1320-KM C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball design provides superior stiffness, enabling the bearing to support substantial radial loads and moderate axial loads from both directions, making it suitable for combined load applications.
- Precision Tapered Bore: The 1:12 taper ensures a tight, interference fit on the shaft, eliminating inner ring creep and enhancing rotational accuracy.
- Optimized Cage Design: The brass cage (M) offers excellent durability and guidance for the balls, contributing to smooth operation and suitability for high-speed applications up to its limiting speed.
- Pre-Lubricated & Ready-to-Use: The bearing comes lubricated, reducing initial setup time and providing immediate protection against wear.
- Robust Material Construction: Manufactured from chrome steel for rings and balls, ensuring high strength, wear resistance, and a long operational lifespan.
