W 628/6-2Z Bearing Product Overview & Core Advantages
The W 628/6-2Z is a single row deep groove ball bearing designed for high-performance applications requiring compact design and reliable operation. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to efficiently handle radial loads while its shielded design (2Z) and pre-applied grease lubrication ensure long service life and minimal maintenance, making it ideal for applications demanding high reliability and cleanliness.
W 628/6-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W 628/6 | Basic bearing designation, indicating a single row deep groove ball bearing with a 6 mm bore diameter. |
| 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 628/6-2Z Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components, including rings, balls, and cage, are made from stainless steel, providing superior corrosion resistance and suitability for harsh environments.
- Effective Contamination Protection: The non-contact shields (2Z) on both sides effectively keep out contaminants like dust and moisture, enhancing bearing life and reliability.
- Optimized for High Speeds: The combination of a stainless steel cage and shielded design contributes to a high limiting speed of 53,000 rpm, making it a capable high-speed bearing.
- Reduced Maintenance: Pre-lubricated with grease, the bearing is ready for use and requires no initial lubrication, offering a maintenance-free solution for its operational lifespan in many applications.
- Standard Precision & Clearance: Manufactured to P0 tolerance class and standard CN radial internal clearance, ensuring consistent performance and easy interchangeability.
