307-Z Bearing Product Overview & Core Advantages
The 307-Z is a high-performance single row deep groove ball bearing designed for robust radial load applications. Engineered with precision Chrome Steel components and a Nylon cage, it delivers reliable operation and extended service life. Its shielded design offers effective contamination protection while its pre-lubricated state ensures immediate, maintenance-free operation upon installation. This bearing is characterized by its high limiting speed and excellent dimensional stability, making it a dependable choice for demanding industrial environments.
307-Z Bearing Model Code Explained, Specifications & Naming Convention
- 307: Basic series designation, indicating a metric deep groove ball bearing with standard dimensions.
- Z: Signifies that the bearing is equipped with a non-contact steel shield on one side. This provides protection against large particulate contaminants while minimizing friction and heat generation, contributing to the high limiting speed.
307-Z Bearing Structural Features & Performance Benefits
Optimized for Radial Loads: The deep groove raceway and single row construction are engineered to efficiently support significant radial dynamic load ratings of up to 7801 lbf.
High-Speed Capability: The lightweight Nylon cage ensures stable ball guidance and reduced centrifugal forces, enabling a high limiting speed of 9,500 rpm. The shielded design further supports this by reducing grease churn and drag.
Dimensional Precision & Stability: Manufactured to P0 tolerance class with a CN radial internal clearance, this bearing provides consistent performance and precise shaft guidance, contributing to overall system accuracy.
Reduced Maintenance: The combination of a shielded seal and factory-applied grease lubrication protects the bearing interior from contaminants and provides long-term lubrication, making it suitable for applications where re-lubrication is difficult.
307-Z Bearing Typical Application Areas
The 307-Z is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring reliable, high-speed operation
