1206-K C/3 Bearing Product Overview & Core Advantages
The 1206-K C/3 is a metric double row angular contact ball bearing engineered for superior performance in demanding applications. Featuring a tapered bore (1:12) design, this precision bearing delivers exceptional rigidity and can accommodate combined radial and axial loads simultaneously. Its double row construction provides high load-carrying capacity in a compact bearing size (30mm bore × 62mm OD × 16mm width), making it ideal for applications requiring high precision and reliability. The bearing comes pre-lubricated and features optimized radial internal clearance (CN group) for stable operation across various conditions.
1206-K C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1206 | Basic bearing designation indicating size series and bore diameter |
| K | Tapered bore with 1:12 taper ratio |
| C/3 | Radial internal clearance group (CN normal clearance) |
1206-K C/3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides enhanced stiffness and can support significant combined radial and axial loads in both directions, making it suitable for applications with complex loading conditions.
Precision Engineering: Manufactured with chrome steel rings and balls, the bearing ensures consistent performance and long service life. The nylon cage contributes to smooth operation and reduced friction at high speeds.
Optimized Performance: With a limiting speed of 15,000 rpm and standard CN radial clearance, this bearing delivers reliable operation across its specified temperature range (-30°C to 110°C). The tapered bore design allows for precise mounting and adjustment on tapered shafts.
Maintenance Efficiency: The open construction with pre-lubrication provides flexibility for specific application lubrication requirements while ensuring immediate operational readiness.
