6309-2Z/C5 Bearing Product Overview & Core Advantages
The 6309-2Z/C5 is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. This shielded bearing offers a robust solution for primarily radial loads, featuring a generous C5 radial internal clearance suitable for applications with thermal expansion or misalignment concerns. Its metric dimensions (45mm bore, 100mm OD, 25mm width) and ABEC 1 precision make it a versatile and reliable choice for high-speed operation up to 6,700 rpm, providing a balance of durability, performance, and value.
6309-2Z/C5 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| -2Z | Non-contact steel shields on both sides | Provides effective contamination protection while maintaining high-speed capability with minimal friction increase. |
| /C5 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature applications and compensates for minor misalignments, enhancing operational reliability. |
6309-2Z/C5 Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing delivers high strength, wear resistance, and long service life under substantial radial dynamic load ratings of 11,915 lbf.
- Optimized for Speed: The deep groove raceway and precision-ground components enable smooth operation at limiting speeds of 6,700 rpm, making it suitable for various motor and drive applications.
- Enhanced Reliability with C5 Clearance: The greater internal clearance prevents pre-loading from thermal expansion, reducing friction and heat generation, which is critical for maintaining performance in thermally demanding environments.
- Shielded Protection: The -2Z shields effectively retain the factory-applied lubricant and exclude larger particulate contaminants, extending relubrication intervals and bearing life in dirty operating conditions.
6309-2Z/C5 Bearing Typical Application Areas
The 6309-2Z/C5 is widely used across various industries due to its robust design and protective features. Common applications include:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Conveyors
- Agricultural Machinery
- Construction Equipment
