306-ZN Bearing Product Overview & Core Advantages
The 306-ZN is a single row deep groove ball bearing engineered for robust radial load capacity and reliable performance in demanding applications. Its shielded design (ZN suffix) provides effective contaminant protection while maintaining high operational efficiency. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing delivers precise rotation and consistent performance. The inclusion of a snap ring groove on the outer ring facilitates secure axial positioning during installation, making it an ideal choice for applications requiring simplified mounting and maintenance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 306 | Basic bearing designation indicating metric dimensions: 30mm bore, 72mm OD, 19mm width |
| Z | Shield on one side for basic contaminant protection |
| N | Snap ring groove on outer ring for axial locating |
306-ZN Bearing Structural Features & Performance Benefits
Enhanced Protection & Simplified Mounting: The shielded construction effectively prevents the ingress of contaminants while the snap ring groove enables secure axial positioning without additional components. This combination ensures extended service life and reduced maintenance requirements.
Robust Load Capacity: With a dynamic load rating of 6677 lbf and static load rating of 4856 lbf, this bearing delivers reliable performance under significant radial loads. The deep groove raceway geometry optimizes contact between balls and raceways for efficient load distribution.
Precision Engineering: Manufactured from chrome steel throughout (rings, balls, and cage) and built to ABEC 1 precision class, the 306-ZN ensures smooth operation and minimal vibration. The CN radial clearance provides optimal internal fit for most industrial applications.
High-Speed Capability: With a limiting speed of 11,000 rpm, this bearing is suitable for high-rotation applications. The all-steel construction maintains dimensional stability across the operating temperature range of -30°C to 120°C.
306-ZN Bearing Typical Application Areas
- Electric Motors and generators requiring reliable radial support
- Industrial Gearboxes and transmission systems
- Material Handling Equipment including conveyor systems
- Agricultural Machinery and implements
- Automotive Components such as alternators and pumps
- Industrial Fans and blowers
