1207 KC3 Bearing Product Overview & Core Advantages
The 1207 KC3 is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and reliable performance under combined loads. Featuring a tapered bore (1:12) and open construction, this precision bearing delivers exceptional stability and can accommodate both radial and axial loads simultaneously. Its optimized bearing dimensions (35mm bore, 72mm OD, 17mm width) provide a compact solution for space-constrained installations while maintaining superior load-carrying capacity.
1207 KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1207 | Basic bearing designation indicating size series and bore diameter |
| K | Tapered bore with 1:12 ratio for precise mounting and adjustment |
| C3 | Greater than normal radial internal clearance for thermal expansion compensation |
1207 KC3 Bearing Structural Features & Performance Benefits
Double Row Design: The double row angular contact configuration provides high rigidity and moment load capacity, making it ideal for applications requiring precise shaft positioning and stability.
Optimized Internal Geometry: Precision-ground raceways and chrome steel balls ensure smooth operation and extended service life under demanding conditions.
Nylon Cage: The nylon cage material contributes to the bearing's high-speed capability (up to 13,000 rpm) by reducing friction and providing excellent guidance.
Tapered Bore Advantage: The 1:12 tapered bore allows for precise axial positioning and secure mounting on adapter sleeves, ensuring optimal performance in high-speed applications.
Enhanced Load Capacity: With a dynamic load rating of 4275 lbf and static load rating of 1350 lbf, this bearing reliably handles combined radial and axial loads in demanding environments.
