1307KC3 Bearing Product Overview & Core Advantages
The 1307KC3 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. Featuring a tapered bore (1:12) and C3 radial internal clearance, this metric bearing excels in handling significant radial forces while maintaining dimensional stability. Its compact bearing dimensions (35mm bore × 80mm OD × 21mm width) make it ideal for space-constrained, high-precision applications where consistent performance is critical.
1307KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1307 | Basic bearing designation indicating 35mm bore diameter |
| K | Tapered bore with 1:12 ratio for precise mounting on tapered shafts |
| C3 | Greater than normal radial internal clearance for thermal expansion applications |
1307KC3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness compared to single row bearings, enabling precise shaft positioning and reduced deflection under heavy radial loads.
Enhanced Load Capacity: Engineered to handle combined loads effectively, with a dynamic load rating of 5962 lbf and static load rating of 1912 lbf, ensuring reliable operation in demanding conditions.
Optimized Performance: The nylon cage contributes to smooth operation at limiting speeds up to 11,000 rpm, while the C3 clearance accommodates thermal expansion in high-speed applications.
Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances, this precision bearing maintains consistent performance across the operating temperature range of -30°C to 110°C.
