W 623 R-2Z Bearing Product Overview & Core Advantages
The W 623 R-2Z is a metric miniature ball bearing designed for compact, high-precision applications requiring reliable performance. As a single row deep groove ball bearing with shielded construction, it excels at handling radial loads efficiently. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its key advantages include a compact flange design for secure mounting, pre-lubrication for immediate use, and suitability for high-speed operation up to 70,000 rpm, making it ideal for applications demanding high rotational accuracy and long service life.
W 623 R-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| W 623 | Basic bearing designation: Miniature deep groove ball bearing series with a 3mm bore, 10mm OD, and 4mm width. | Defines the core dimensions and type for compact design applications. |
| R | Flanged outer ring. | Enables simplified and secure mounting, ideal for positioning and preventing axial movement. |
| 2Z | Non-contact shields on both sides. | Offers effective protection against contamination while maintaining high-speed capability and low friction. |
W 623 R-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 durability, suitable for harsh environments and clean applications.
- Flanged Design for Enhanced Mounting: The integrated flange on the outer ring simplifies assembly, ensures precise axial location, and increases mounting rigidity.
- Optimized for High-Speed Operation: The deep groove raceway and low-friction shielded design contribute to a high limiting speed of 70,000 rpm, supporting demanding rotational requirements.
- Pre-Lubricated & Low Maintenance: Filled with grease, the bearing is ready for immediate use, reducing initial setup time and offering long-term, maintenance-free operation within its specified temperature range.
- Standard Precision & Clearance: Manufactured to P0 tolerance class and standard CN radial internal clearance, ensuring consistent performance and interchangeability for general precision applications.
