6309-2ZNR Bearing Product Overview & Core Advantages
The 6309-2ZNR is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This shielded bearing features a snap ring groove on its outer ring, enabling secure axial location within a housing without complex machining. Its design is optimized to handle significant radial loads while offering reliable operation. Manufactured with precision tolerances (P0 class) and pre-lubricated with grease, it delivers high reliability, long service life, and is suitable for applications requiring maintenance-free operation.
6309-2ZNR Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6309 | Standard designation for a single row deep groove ball bearing with a 45mm bore, 100mm OD, and 25mm width. | Defines the core bearing dimensions and basic type. |
| 2Z | Identifies the bearing as having shields on both sides. | Provides effective protection against contamination from solid particles, enhancing bearing life. |
| NR | Indicates the outer ring has a snap ring groove and is supplied with a snap ring. | Simplifies assembly and provides secure axial location, reducing housing design complexity and cost. |
6309-2ZNR Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The single row deep groove construction and high-quality chrome steel components enable it to support a high radial dynamic load rating of 12,432 lbf and a radial static load rating of 7,081 lbf, making it suitable for heavy-duty applications.
- Secure Axial Location: The integrated snap ring groove and supplied snap ring prevent axial movement of the bearing outer ring within the housing, a critical feature for maintaining precise alignment in assemblies.
- Contamination Protection & Maintenance-Free Operation: The non-contact steel shields (2Z) effectively retain the factory-applied grease lubrication and exclude larger contaminants. This sealed-for-life design eliminates the need for re-lubrication in many applications.
- High-Speed Capability: The standard CN radial internal clearance and stainless steel cage contribute to stable operation, supporting a limiting speed of 7,500 rpm.
- Wide Temperature Range: The bearing is capable of operating within a temperature range of -30°C to 120°C, accommodating various industrial environments.
