W 608-2Z/VT811 Bearing Product Overview & Core Advantages
The W 608-2Z/VT811 is a single row deep groove ball bearing designed for high reliability in demanding applications. Engineered from stainless steel for excellent corrosion resistance, this bearing excels at handling radial loads and is optimized for smooth, low-noise operation. Its compact design, featuring a shielded configuration, protects against contamination while maintaining operational integrity. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance and is an ideal choice for applications requiring a durable, maintenance-free solution.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| W | Designates a stainless steel bearing. |
| 608 | Standard bearing series designation, indicating a metric deep groove ball bearing with an 8 mm bore, 22 mm OD, and 7 mm width. |
| 2Z | Signifies a non-contact shield on both sides. This provides effective protection against contaminants while minimizing friction and allowing for higher limiting speeds compared to contact seals. |
| /VT811 | Indicates the bearing is supplied without lubrication ("None" per specifications), allowing for application-specific lubrication or use in environments where standard greases are not suitable. |
W 608-2Z/VT811 Bearing Structural Features & Performance Benefits
- Corrosion Resistance: Constructed entirely from stainless steel rings and balls, this bearing is inherently resistant to rust and corrosion, making it suitable for harsh environments, including those with exposure to moisture or chemicals.
- Contamination Protection: The 2Z shields on both sides effectively prevent the ingress of solid contaminants like dust and debris, enhancing bearing service life and reliability without significantly increasing rotational torque.
- Precision & Smooth Operation: Manufactured to ABEC 1 (ISO P0) precision class with a standard CN radial internal clearance, it ensures smooth, quiet, and vibration-free running, which is critical for sensitive equipment.
- High-Speed Capability: The combination of a deep groove raceway, low-friction stainless steel components, and non-contact shields enables a high limiting speed of 48,000 rpm.
- Application Flexibility: Being supplied without lubrication offers maximum flexibility. Engineers can select a specialized lubricant tailored to specific operational requirements, such as extreme temperatures or food-grade compatibility.
