1305C3 Bearing Product Overview & Core Advantages
The 1305C3 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loading conditions. This precision bearing features an open design and is pre-lubricated for immediate operation. Its compact construction enables efficient space utilization while providing excellent capability to handle significant radial loads and moderate axial loads in both directions. Manufactured with tight dimensional tolerances and C3 radial internal clearance, it ensures optimal performance in applications with thermal expansion considerations.
Model Code Technical Breakdown
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| 1305 | Standard bore diameter 25mm, outside diameter 62mm | Standard bearing dimensions for interchangeability |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature applications |
| Open | No seals or shields | Allows for custom lubrication regimes and higher speed capability |
1305C3 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.
Superior Load Capacity: Engineered to handle combined loads effectively, with a dynamic load rating of 4275 lbf and static load rating of 1215 lbf, ensuring reliable performance in demanding conditions.
Optimized High-Speed Performance: The nylon cage contributes to reduced friction and allows for limiting speeds up to 15,000 rpm, making it suitable for high-speed applications.
Precision Engineering: Manufactured with tight tolerances (bore: -0.01mm to 0) and chrome steel components for consistent performance and long service life.
Thermal Compatibility: The C3 clearance accommodates differential thermal expansion between bearing components and housing, preventing premature failure in temperature-varying environments.
