1206 KC3 Bearing Product Overview & Core Advantages
The 1206 KC3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and precision. This metric system bearing features a tapered bore (1:12) for secure shaft mounting and is pre-lubricated for immediate use. Its double row design enables it to support significant combined loads (radial and axial) simultaneously, making it an ideal choice for compact arrangements where high reliability and load capacity are critical. The optimized internal geometry and high-quality materials contribute to its stable performance and long service life.
1206 KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1206 | Standard bore diameter (30 mm) and series designation. |
| K | Indicates 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. |
1206 KC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior rigidity and enables the bearing to handle substantial radial loads and moderate axial loads from both directions, offering excellent stability in combined loading scenarios.
- Precision Tapered Bore: The 1:12 tapered bore ensures a tight, secure fit on the shaft, minimizing slippage and maintaining precise alignment, which is crucial for high-performance applications.
- Optimized Internal Clearance: The C3 clearance is engineered for applications where thermal expansion or interference fits are a factor, preventing excessive preload and ensuring smooth operation.
- Lightweight & Durable Cage: The nylon cage offers low friction, quiet operation, and is suitable for the specified temperature range and limiting speed.
- Ready-to-Use Lubrication: The bearing comes pre-lubricated, facilitating easy installation and immediate operation, reducing maintenance downtime.
1206 KC3 Bearing Typical Application Areas
This bearing is well-suited for a variety of industrial machinery and equipment, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment
- Agricultural Machinery
