Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6306 | Basic bearing series: Deep Groove Ball Bearing with 30mm bore, 72mm OD, 19mm width. |
| 2Z | Shielded on both sides. Provides effective protection against contaminant ingress while allowing for high-speed operation. |
| C4 | Radial internal clearance greater than Normal (CN). Ideal for applications with thermal expansion or where interference fits are used. |
| WT | Bearing is supplied without lubrication (None). |
6306-2Z/C4WT Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove raceway design enables the bearing to handle significant radial loads (Dynamic: 6002 lbf, Static: 3372 lbf) efficiently.
- Contamination Protection: The shielded (2Z) design on both sides acts as a physical barrier, protecting the internal components from dust and debris, thereby enhancing operational reliability.
- Thermal & Fit Adaptability: The C4 radial clearance provides extra internal space, making the bearing suitable for applications prone to thermal expansion or where tight shaft and housing fits are required, preventing binding and premature failure.
- High-Speed Capability: With a limiting speed of 9,600 rpm, this bearing is designed for demanding high-speed operations, supported by its precision construction and shielded design that minimizes friction.
- Material Integrity: Manufactured entirely from chrome steel for the rings, balls, and cage, ensuring high strength, wear resistance, and consistent performance under load.
6306-2Z/C4WT Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial applications, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- General machinery requiring robust radial load support and contamination protection.
