1320 KM/C3 Bearing Product Overview & Core Advantages
The 1320 KM/C3 is a double row angular contact ball bearing designed for demanding industrial applications requiring high load capacity and rigidity. This metric bearing features a tapered bore (1:12) for secure shaft mounting and is pre-lubricated for immediate operation. Its primary advantage lies in its ability to support significant radial loads while maintaining stable operation. The C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or heavy interference fits, ensuring reliable performance under challenging conditions.
1320 KM/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1320 | Basic bearing designation indicating dimensions (100mm bore, 215mm OD) |
| KM | Tapered bore (1:12) designation for conical adapter sleeve mounting |
| C3 | Radial internal clearance greater than normal, suitable for thermal expansion and heavy interference fits |
1320 KM/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior rigidity and can handle substantial radial loads with a dynamic rating of 32,175 lbf and static rating of 12,825 lbf.
- Precision Tapered Bore: The KM designation indicates a 1:12 tapered bore that ensures secure mounting on shafts using adapter sleeves, preventing slippage under heavy loads.
- Optimized Material Selection: Constructed from chrome steel rings and balls with a brass cage for durability, corrosion resistance, and stable operation at temperatures from -30°C to 110°C.
- Enhanced Operational Range: The C3 clearance accommodates thermal expansion and interference fits, while the lubricated design supports operation up to 4,000 rpm limiting speed.
