309S Bearing Product Overview & Core Advantages
The 309S single row deep groove ball bearing is a precision bearing designed for robust radial load applications. Featuring an open design and manufactured to ABEC 1 (ISO P0) tolerance standards, it delivers reliable performance and high rotational accuracy. Its chrome steel construction provides excellent durability, making it suitable for a wide operating temperature range from -30°C to 120°C. This bearing is engineered for applications demanding consistent performance under substantial radial dynamic loads of up to 12,364 lbf.
309S Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 309S | Standard bearing series designation, defining the core bearing dimensions (45mm bore, 100mm OD, 25mm width). |
| Open (Seal Type) | No integral seals or shields, allowing for higher limiting speeds and facilitating custom lubrication regimes. |
| CN (Clearance) | Specifies standard radial internal clearance for normal operating conditions. |
| None (Lubrication) | Supplied without grease, providing flexibility for the user to apply a lubricant optimized for their specific application requirements. |
309S Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove raceway and chrome steel components are engineered to handle significant radial dynamic and static loads, ensuring long service life.
- Precision Performance: Manufactured to ABEC 1 tolerances, this bearing offers smooth operation and reduced vibration, which is critical for maintaining system accuracy.
- Optimized for Speed: The open construction and chrome steel cage contribute to a high limiting speed of 7,500 rpm, making it a capable high-speed bearing option.
- Material Integrity: Constructed entirely from chrome steel, the bearing provides high hardness, wear resistance, and dimensional stability across its specified temperature range.
