309SZZC Bearing Product Overview & Core Advantages
The 309SZZC is a single row deep groove ball bearing designed for robust performance in general industrial applications. Engineered with metric dimensions and manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers a reliable solution for handling primarily radial loads. Its shielded (ZZ) construction provides effective protection against contaminant ingress, enhancing service life. The bearing is supplied without lubrication, allowing for application-specific greasing, and operates effectively within a temperature range of -30°C to 120°C. Its core advantages include a high radial dynamic load rating of 12,364 lbf, a substantial radial static load rating of 9,892 lbf, and a limiting speed of 7,500 rpm, making it a versatile and durable choice for a wide array of machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 309 | Standard bore diameter code, corresponding to a 45 mm bore. |
| S | Indicates a standard radial internal clearance of CN group. |
| ZZ | Denotes shielded on both sides. This non-contact seal protects the bearing interior from large contaminants while minimizing friction. |
| C | Specifies the cage material, which in this case is made from Chrome Steel for strength and durability. |
309SZZC Bearing Structural Features & Performance Benefits
- Robust Construction: The single row deep groove raceway and high-quality Chrome Steel rings and balls provide excellent resistance to wear and fatigue, ensuring a long operational lifespan under demanding conditions.
- High Load Capacity: With a radial dynamic load rating of 12,364 lbf and a static load rating of 9,892 lbf, this bearing is engineered to handle significant radial forces, making it suitable for applications with substantial mechanical stress.
- Effective Contamination Protection: The ZZ shields on both sides serve as a primary defense against dust and debris, helping to maintain internal cleanliness and lubricant integrity without the high torque associated with contact seals.
- Precision & Stability: Manufactured to ABEC 1 (ISO P0) tolerance class with a CN clearance, this bearing offers reliable running accuracy and smooth operation, contributing to reduced vibration and noise in the assembly.
