W 608-2Z/R799 Bearing Product Overview & Core Advantages
The W 608-2Z/R799 is a metric single row deep groove ball bearing designed for exceptional performance in compact applications. Engineered with stainless steel rings and balls, it offers excellent corrosion resistance. A key feature is its integral shields (2Z), which effectively retain lubrication and exclude contaminants, enhancing service life. This bearing is precision-manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring reliable operation and high rotational accuracy, making it ideal for applications demanding high reliability and smooth running.
W 608-2Z/R799 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| W | Designates a stainless steel bearing. |
| 608 | Standard bearing series number, defining the bearing dimensions: 8mm bore, 22mm OD, 7mm width. |
| 2Z | Signifies bearing is equipped with shields on both sides. This provides effective protection against contamination. |
| /R799 | Indicates the specific food-grade grease used for lubrication, suitable for the specified temperature range. |
W 608-2Z/R799 Bearing Structural Features & Performance Benefits
- Robust Construction for Radial Loads: The single row deep groove raceway and complement of stainless steel balls are optimized to carry significant radial dynamic loads (up to 447 lbf).
- Shielded for Longevity: The non-contact shields (2Z) protect the internal components from dust and other particulates, contributing to a maintenance-free design and extended service life without re-lubrication.
- Precision and Speed: Manufactured to ABEC 1 precision with a CN radial internal clearance, this bearing ensures smooth operation and is capable of high limiting speeds (48,000 rpm).
- Corrosion Resistance: Constructed entirely from stainless steel, the bearing is highly resistant to rust and corrosion, making it suitable for harsh environments and washdown applications.
W 608-2Z/R799 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and small gearboxes
- Food and Beverage Processing Equipment (due to its food-grade grease and stainless construction)
- Medical Devices and laboratory instruments
- Office Automation Equipment such as printers and scanners
- Fans, blowers, and other light-duty machinery
