1215KJC3 Bearing Product Overview & Core Advantages
The 1215KJC3 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric system bearing features a tapered bore (1:12) for secure shaft mounting and is optimized to handle significant radial loads. Its double row construction provides high rigidity and stable operation, making it suitable for demanding industrial environments. The bearing comes pre-lubricated and features C3 radial internal clearance, accommodating thermal expansion in high-speed applications.
1215KJC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1215 | Basic bearing designation with 75mm bore diameter |
| K | Tapered bore (1:12 ratio) for precise mounting |
| J | Steel cage construction |
| C3 | Greater than normal radial internal clearance for thermal expansion management |
1215KJC3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row angular contact configuration provides enhanced stiffness and stability under heavy radial loads, reducing deflection and maintaining precision alignment.
Superior Load Capacity: Engineered to handle substantial radial dynamic loads (8775 lbf) and radial static loads (3510 lbf), ensuring reliable performance in demanding applications.
Optimized Speed Performance: With a limiting speed of 6,700 rpm, the bearing delivers excellent high-speed capabilities supported by its steel cage and proper internal clearance.
Precision Engineering: Manufactured from chrome steel for both rings and balls, ensuring durability and consistent performance across the operating temperature range of -30°C to 110°C.
Mounting Efficiency: The tapered bore design facilitates precise mounting and dismounting, while the generous chamfer dimensions (1.5mm) ease installation.
