1206KC3 Bearing Product Overview & Core Advantages
The 1206KC3 is a double row angular contact ball bearing designed for applications requiring high rigidity and precise operation. Featuring a metric taper bore (1:12), this bearing excels at handling combined radial and axial loads simultaneously. Its compact bearing dimensions (30mm bore, 62mm OD, 16mm width) and C3 radial internal clearance make it ideal for precision arrangements where thermal expansion compensation is critical. Manufactured with chrome steel rings and balls combined with a nylon cage, it delivers reliable performance in demanding industrial environments.
1206KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1206 | Basic designation indicating bore diameter (30mm) and series |
| K | Tapered bore with 1:12 ratio for secure shaft mounting |
| C3 | Greater than normal radial internal clearance for thermal expansion compensation |
1206KC3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides enhanced stiffness and stability, making it suitable for applications requiring precise shaft positioning and minimal deflection under load.
Superior Load Capacity: Engineered to handle combined radial and axial loads efficiently, with a dynamic load rating of 3510 lbf and static load rating of 1046 lbf.
Optimized Performance: The nylon cage contributes to smooth operation at limiting speeds up to 15,000 rpm, while the open design allows for customized lubrication strategies.
Precision Engineering: Tight dimensional tolerances on bore (-0.01mm to 0) and outside diameter (-0.013mm to 0) ensure consistent performance in precision applications.
