306/C3 Bearing Product Overview & Core Advantages
The 306/C3 is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Its primary advantage lies in its ability to accommodate high radial loads and moderate axial loads in both directions. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing offers a robust and cost-effective solution for general machinery. The specified C3 radial internal clearance makes it particularly suitable for applications involving thermal expansion or where interference fits are used, ensuring optimal performance under operational conditions.
306/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 306 | Basic bearing designation, indicating a metric series deep groove ball bearing with a 30mm bore diameter, 72mm outside diameter, and 19mm width. |
| /C3 | Indicates a greater than normal radial internal clearance. This is critical for applications with shaft or housing misalignment, high-speed operation, or where temperature differentials can cause expansion. |
306/C3 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built with chrome steel rings, balls, and cage, this bearing delivers high strength and durability. It features a radial dynamic load rating of 6677 lbf and a radial static load rating of 4856 lbf, making it capable of handling significant radial stresses.
- Optimized for Operational Demands: The open seal type design allows for easy re-lubrication and is ideal for clean environments or where specific lubricants are required. The C3 clearance provides operational stability by accommodating thermal expansion and preventing preload, which can lead to premature failure.
- High-Speed Capability: With a limiting speed of 11,000 rpm, this bearing is engineered for efficient high-speed operation, supported by its precision-ground components.
- Precision and Reliability: Conforming to ABEC 1 | ISO P0 tolerance class ensures consistent quality and reliable performance, contributing to reduced vibration and noise in the final application.
306/C3 Bearing Typical Application Areas
This versatile 306/C3 bearing is commonly specified in:
- Electric Motors and Generators
- Industrial Gearboxes
- Agricultural Machinery
- Material Handling Equipment (e.g., conveyor pulleys)
- General Industrial Machinery requiring robust and reliable radial support.
