6309-2Z/GFF/R806 Bearing Product Overview & Core Advantages
The 6309-2Z is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Its core advantage lies in its ability to accommodate significant radial loads and moderate axial loads in both directions. Featuring integral shielded seals, this bearing offers built-in contamination protection and is supplied without lubrication, providing flexibility for specific application requirements. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent quality and dependable operation, making it a versatile and cost-effective solution for general machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6309 | Standard series designation for a medium-duty, single row deep groove ball bearing with a 45mm bore. |
| 2Z | Indicates the bearing is shielded on both sides. These non-contact steel shields protect the internal components from large particulate contaminants while minimizing friction. |
6309-2Z/GFF/R806 Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from chrome steel, including the rings, balls, and cage, this bearing provides high strength and durability for long service life under dynamic and static loads.
Contamination Protection: The 2Z shields effectively retain the factory-supplied grease (if lubricated by the user) and protect the bearing's interior from large contaminants, enhancing reliability in dusty environments.
High-Speed Capability: With a limiting speed of 6,700 rpm, the 6309-2Z is suitable for a broad spectrum of high-speed applications. The deep groove raceway and optimized cage design contribute to stable operation at these velocities.
Standard Tolerances & Clearance: Built to ABEC 1 (ISO P0) tolerance class with a CN group radial internal clearance, this bearing offers excellent value and performance for most industrial uses without the need for ultra-precision.
