309SZZCG Bearing Product Overview & Core Advantages
The 309SZZCG is a single row deep groove ball bearing designed for reliable performance in demanding industrial applications. Engineered with shielded construction, it effectively protects against contaminant ingress while maintaining low operating torque. This bearing excels at handling radial loads and offers a high limiting speed of 7,500 rpm. Manufactured to ABEC 1 / ISO P0 tolerance standards, it provides consistent, high-quality performance for general precision applications where cost-effectiveness and durability are key.
Model Code Breakdown
- 309: Basic series designation, indicating a medium duty bearing with a 45mm bore.
- S: Denotes the bearing is manufactured from Chrome Steel.
- ZZ: Signifies that the bearing is equipped with non-contact shields on both sides. This provides excellent protection against dust and other particles without significantly increasing friction.
- CG: Indicates the standard radial internal clearance group is "CN" (Normal).
309SZZCG Bearing Structural Features & Performance Benefits
The single row deep groove design is a versatile and robust solution. The raceways are precision-ground to facilitate smooth rotation and efficient radial load distribution. The use of chrome steel for all critical components (rings, balls, cage) ensures high strength, wear resistance, and a long operational lifespan. The shielded (ZZ) design is a key feature, offering superior contamination exclusion compared to open bearings, making it suitable for environments where debris is a concern. Being supplied without lubrication allows for application-specific greasing, providing flexibility for specialized operational conditions.
309SZZCG Bearing Typical Application Areas
This bearing's balance of performance, protection, and value makes it ideal for a wide range of equipment, including:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Conveyors
- Agricultural Machinery
- HVAC Fans and Blowers
