1309 C3 Bearing Product Overview & Core Advantages
The 1309 C3 is a double row angular contact ball bearing designed for applications requiring high radial load capacity and operational stability. This precision bearing features an open design without seals, allowing for optimal lubrication flow and heat dissipation. Its C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, ensuring consistent performance under varying operational conditions. The combination of a nylon cage and chrome steel construction delivers excellent high-speed capability and durability.

|---|---|
| 1309 | Basic bearing designation indicating bearing dimensions: 45mm bore, 100mm OD, 25mm width |
| C3 | Radial internal clearance greater than normal, suitable for applications with thermal gradients or interference fits |
1309 C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior radial stiffness and can handle significant combined loads, making it ideal for applications requiring stable rotational accuracy under heavy loading conditions.
Optimized High-Speed Performance: The nylon cage ensures smooth operation at high rotational speeds (up to 8,500 rpm), reducing friction and heat generation while maintaining dimensional stability.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, this bearing offers excellent wear resistance and fatigue life, ensuring reliable performance in demanding industrial environments.
Thermal Adaptation: The C3 clearance accommodates thermal expansion during operation, preventing binding and maintaining optimal performance across the specified temperature range of -30°C to 110°C.
