W 6306-2Z Bearing Product Overview & Core Advantages
The W 6306-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with stainless steel rings, balls, and cage, it offers superior corrosion resistance. Its key advantage lies in its ability to efficiently handle radial loads while accommodating moderate axial loads in both directions. The integral shielded design (2Z) and factory-applied grease lubrication ensure long-term, maintenance-free operation, making it a compact and highly reliable solution for applications requiring precision and durability.
W 6306-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| W | Designates a stainless steel bearing series. |
| 6306 | Standard bearing series number, defining the bearing dimensions (30mm bore, 72mm OD, 19mm width). |
| 2Z | Signifies bearing with shields on both sides. This provides effective protection against contamination while allowing for higher limiting speeds compared to contact seals. |
W 6306-2Z Bearing Structural Features & Performance Benefits
- High Corrosion Resistance: The all-stainless steel construction (rings, balls, cage) ensures reliable performance in harsh, corrosive environments and is suitable for wash-down applications.
- Robust Load Capacity: The deep groove raceway and optimized geometry enable high radial dynamic load rating (5148 lbf) and radial static load rating (3372 lbf), providing dependable support.
- Optimized Speed Performance: The combination of a low-friction stainless steel cage and non-contact shields contributes to a high limiting speed of 11,000 rpm, making it a capable high-speed bearing.
- Maintenance-Free Operation: With factory-fitted grease lubrication and shields (2Z) on both sides, the bearing is sealed for life, preventing lubricant leakage and contaminant ingress, thus reducing maintenance needs.
- Standard Tolerances: Manufactured to P0 tolerance class and standard CN radial internal clearance, ensuring consistent and predictable performance for a wide range of applications.
W 6306-2Z Bearing Typical Application Areas
This versatile bearing is ideally suited for applications requiring corrosion resistance, high-speed capability, and low maintenance. Key industries and equipment include:
- Food and Beverage Processing Machinery
- Medical and Pharmaceutical Equipment
- Chemical Processing Pumps and Mixers
- Marine and Submerged Applications
