W 6305-2Z Bearing Product Overview & Core Advantages
The W 6305-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Constructed entirely from stainless steel, it offers superior corrosion resistance. Its key advantage lies in its ability to handle significant radial loads while also accommodating moderate axial loads in both directions. The integrated shielded (2Z) design provides effective contaminant protection and retains factory-applied grease lubrication, making it a compact, reliable, and often maintenance-free solution for high-precision and high-reliability environments.
W 6305-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W | Designates a stainless steel construction for the bearing rings and balls. |
| 6305 | The standard bearing size designation (35mm bore, 62mm OD, 17mm width). |
| 2Z | Signifies that the bearing is shielded on both sides. This provides excellent protection against contaminants while allowing for higher limiting speeds compared to contact seals. |
W 6305-2Z Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components, including rings, balls, and the cage, are made from stainless steel, ensuring excellent corrosion resistance and suitability for harsh or washdown environments.
- High Load Capacity: With a dynamic load rating of 4002 lbf and a static load rating of 2518 lbf, this bearing is engineered to handle substantial radial loads effectively.
- Optimized for Speed: The combination of a stainless steel cage and non-contact shields contributes to a high limiting speed of 13,000 rpm, making it suitable for various high-speed applications.
- Maintenance-Free Operation: The 2Z shields seal in the factory-applied grease, providing long-term lubrication and protecting against particle ingress, which extends service life and reduces maintenance needs.
- Standard Precision: Manufactured to P0 tolerance class with CN radial internal clearance, it delivers reliable and consistent performance for a wide range of industrial uses.
