6306-ZNB/C3 Bearing Product Overview & Core Advantages
The 6306-ZNB/C3 is a single row deep groove ball bearing engineered for robust performance in demanding applications. This metric bearing features a shielded design and a C3 radial internal clearance, making it exceptionally suitable for applications with thermal expansion or where interference fits are used. Its snap ring groove on the outer ring simplifies axial location and mounting, enhancing assembly efficiency. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable operation and consistent performance for general industrial use.
6306-ZNB/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| Z | One Shield | Protects against contamination from one side. |
| N | Snap Ring Groove | Facilitates secure axial positioning and simplifies housing design. |
| B | Enhanced Internal Design | Optimized for higher load capacity. |
| /C3 | Greater than Normal Radial Internal Clearance | Accommodates thermal expansion, ideal for high-temperature or tight-fit applications. |
6306-ZNB/C3 Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove construction and enhanced internal design (B suffix) provide a high radial dynamic load rating of 6002 lbf and a radial static load rating of 3372 lbf, enabling reliable support for substantial radial loads.
- Robust Construction: All components, including rings, balls, and cage, are manufactured from Chrome Steel, ensuring high strength, durability, and resistance to wear.
- Simplified Mounting & Axial Location: The snap ring groove (N suffix) on the outer ring allows for easy and secure axial fixation, reducing assembly complexity and cost.
- Contaminant Protection: The shielded (Z) design on one side helps retain lubrication and exclude larger contaminants, contributing to a longer service life.
- Operational Flexibility: The C3 clearance provides operational stability in applications prone to thermal expansion or where shaft and housing fits create a reduction in inherent bearing clearance.
6306-ZNB/C3 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- General Machinery requiring reliable radial load support and simplified mounting.
