1306C3 Bearing Product Overview & Core Advantages
The 1306C3 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. This precision bearing features an open design with optimized internal geometry that enables it to simultaneously handle substantial radial loads and moderate axial loads in both directions. Its compact bearing dimensions (30mm bore × 72mm OD × 19mm width) make it ideal for space-constrained applications while maintaining excellent operational stability. The C3 radial internal clearance provides optimal performance in applications with thermal expansion considerations.
1306C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1306 | Standard bearing designation indicating 30mm bore diameter and medium cross-section |
| C3 | Radial internal clearance greater than normal, suitable for applications with thermal expansion or interference fits |
1306C3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides enhanced stiffness compared to single row bearings, making it ideal for applications requiring minimal deflection under load. This design ensures stable operation and precise positioning capabilities.
Superior Load Capacity: Engineered to handle combined loads effectively, this bearing can accommodate both radial forces and bidirectional axial loads simultaneously. With a dynamic load rating of 5062 lbf and static load rating of 1530 lbf, it delivers reliable performance in demanding applications.
Optimized High-Speed Performance: The nylon cage contributes to reduced friction and lower operating temperatures, enabling a limiting speed of 13,000 rpm. This makes the bearing suitable for high-speed applications where smooth operation is critical.
Precision Engineering: Manufactured from chrome steel for both rings and balls, the bearing offers excellent durability and wear resistance. The precise dimensional tolerances ensure consistent performance and easy installation.
