306S Bearing Product Overview & Core Advantages
The 306S is a single row deep groove ball bearing designed for outstanding performance in general industrial applications. Engineered to primarily accommodate radial loads, this open-type bearing is characterized by its high precision, reliable operation, and robust construction. Manufactured from high-grade chrome steel for all critical components, it offers excellent durability and a long service life. Its ABEC 1 (ISO P0) tolerance class ensures consistent performance, making it a cost-effective and versatile solution for a wide range of machinery and equipment.
306S Bearing Model Code Explained, Specifications & Naming Convention
The model number 306S can be broken down as follows:
- 306: Standard bore diameter code, indicating a 30 mm bore.
- S: Designates a bearing manufactured with enhanced dimensional stability and heat treatment, suitable for higher operating temperatures.
- Seal Type: Open - Allows for high-speed operation and easy re-lubrication.
- Lubrication: None - Supplied without grease, providing flexibility for the user to select the optimal lubricant for the application.
- Internal Clearance: CN - Standard radial internal clearance for normal operating conditions.
306S Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open design and absence of contact seals minimize friction and heat generation, enabling a high limiting speed of 11,000 rpm.
- Robust Load Capacity: With a dynamic load rating of 6677 lbf and a static load rating of 4856 lbf, this bearing is built to handle significant radial forces in demanding environments.
- Precision Engineering: Manufactured to ABEC 1 (ISO P0) tolerance standards with tight dimensional control on the bore diameter, outside diameter, and width, ensuring smooth and precise rotation.
- Material Integrity: The use of chrome steel for the rings, balls, and cage provides high hardness, wear resistance, and consistent performance across its specified temperature range of -30°C to 120°C.
306S Bearing Typical Application Areas
The 306S bearing is ideally suited for a variety of industrial applications, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Fans
- Material Handling Conveyors
- Agricultural Machinery
- General Machinery where reliable radial load support is required.
