1307KJC3 Bearing Product Overview & Core Advantages
The 1307KJC3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance under combined loads. Featuring a metric tapered bore (1:12) and open construction, this precision bearing excels in handling significant radial loads while maintaining dimensional stability. Its optimized internal geometry and C3 radial internal clearance make it suitable for applications with thermal expansion or demanding fit conditions, offering robust performance in a compact design with a 21mm width.

| Code Segment | Technical Meaning |
|---|---|
| 1307 | Basic bearing designation: 35mm bore, 80mm OD, 21mm width |
| K | Tapered bore with 1:12 ratio for secure shaft mounting |
| JC3 | Steel cage construction with C3 radial internal clearance for thermal expansion accommodation |
1307KJC3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial stiffness and can accommodate combined loads effectively. With a dynamic load rating of 5962 lbf and static load rating of 1912 lbf, this bearing offers reliable performance in heavy-duty applications.
Precision Engineering: Manufactured from chrome steel for both rings and balls, the bearing ensures consistent performance and long service life. The steel cage maintains proper ball spacing for smooth operation.
Thermal Adaptation: The C3 radial clearance allows for thermal expansion during operation, preventing binding or excessive preload in applications where temperature variations occur.
Mounting Efficiency: The tapered bore design facilitates precise mounting and dismounting using adapter sleeves, ensuring proper fit and alignment on the shaft.
