309-2Z Bearing Product Overview & Core Advantages
The 309-2Z is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Engineered with metric dimensions, it excels at handling primarily radial loads and offers robust operation due to its shielded construction. A key advantage is its pre-lubricated and shielded design, which provides effective protection against contamination and offers long-term, maintenance-free service. Manufactured with high-grade chrome steel and a lightweight nylon cage, it delivers a favorable balance of durability, high-speed capability, and smooth operation.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 309 | Basic bearing series, defining the standard dimensions: 45mm bore, 100mm OD, 25mm width. |
| 2Z | Indicates the bearing is fitted with shields on both sides. This provides excellent protection against solid contaminants while allowing for high-speed operation with minimal friction. |
309-2Z Bearing Structural Features & Performance Benefits
- Robust Construction & Load Capacity: The single row deep groove raceway and high-quality chrome steel construction provide a high radial dynamic load rating of 12,364 lbf and a radial static load rating of 9,892 lbf, ensuring reliable performance under significant stress.
- High-Speed Performance: The combination of the low-friction nylon cage and grease lubrication enables a high limiting speed of 6,000 rpm, making it suitable for demanding applications.
- Maintenance-Free & Long Service Life: The 2Z shields seal in the factory-applied grease and effectively keep out debris. This pre-lubricated design eliminates the need for re-lubrication, reducing maintenance costs and downtime.
- Precision & Stability: Manufactured to P0 (Normal) tolerance class with a standard CN radial internal clearance, this bearing offers consistent and precise operation for general industrial use.
