6309-2Z/C2ELHT23VP171 Bearing Product Overview & Core Advantages
The 6309-2Z/C2 is a metric single row deep groove ball bearing engineered for reliable performance in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads while offering operational stability. The bearing features integrated shields (2Z) that protect against contamination, and a C2 radial internal clearance optimized for specific fit and thermal conditions. Manufactured from high-grade chrome steel and conforming to ABEC 1 | ISO P0 tolerance standards, it provides a robust and cost-effective solution for general industrial machinery requiring consistent operation.
6309-2Z/C2ELHT23VP171 Bearing Model Code Explained, Specifications & Naming Convention
- 6309: Basic model number denoting a medium-duty, single row deep groove ball bearing with a 45mm bore, 100mm OD, and 25mm width.
- 2Z: Signifies that the bearing is shielded on both sides. These non-contact steel shields retain lubrication and protect the internal components from large particulate contaminants, enhancing service life.
- C2: Indicates a radial internal clearance that is less than the Normal (CN) group. This C2 clearance is selected for applications involving tight interference fits or where operational temperatures are expected to cause significant thermal expansion of the inner ring.
6309-2Z/C2ELHT23VP171 Bearing Structural Features & Performance Benefits
The design of the 6309-2Z/C2 delivers distinct performance benefits. The single row deep groove geometry is versatile and capable of supporting high radial dynamic load ratings (11,915 lbf). The chrome steel construction of the rings, balls, and cage ensures high strength and durability. The presence of shields on both sides (2Z) makes it a pre-lubricated and effectively sealed unit, reducing the need for frequent re-lubrication and protecting against premature failure from contamination. The specified C2 clearance provides precise control over internal bearing play, which is critical for applications with predictable thermal expansion or tight press fits, ensuring optimal performance and reducing noise and vibration.
6309-2Z/C2ELHT23VP171 Bearing Typical Application Areas
This bearing is widely used across various industrial sectors due to its balanced performance and protective features. Common applications include:
- Electric Motors
- Industrial Gearboxes
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring reliable, shielded bearing solutions.
