W 619/9-2Z Bearing Product Overview & Core Advantages
The W 619/9-2Z is a single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantages include the ability to handle significant radial loads, smooth operation facilitated by shielded construction that retains lubrication and excludes contaminants, and a compact design ideal for space-constrained assemblies. This bearing is a robust solution for applications demanding high rotational speeds and long-term, maintenance-free operation.
W 619/9-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| W 619/9 | Basic Bearing Designation | Indicates a deep groove ball bearing series with a 9 mm bore diameter. |
| -2Z | Seal Type | Signifies the bearing is equipped with non-contact shields on both sides. This design effectively retains the pre-applied grease lubrication and protects against large particulate contaminants, contributing to its maintenance-free characteristic. |
W 619/9-2Z Bearing Structural Features & Performance Benefits
- Full Stainless Steel Construction: The rings, balls, and cage are all made from stainless steel, providing superior corrosion resistance and making the bearing suitable for harsh environments and washdown applications.
- Optimized Load Capacity: The deep groove raceway and single row design are engineered to support high radial dynamic load ratings (438 lbf), ensuring reliable performance under demanding conditions.
- High-Speed Capability: The combination of a low-friction stainless steel cage and effective shielded design allows for a high limiting speed of 40,000 rpm, suitable for demanding rotational applications.
- Precision and Stability: Manufactured to P0 tolerance class with a standard CN radial internal clearance, this bearing offers consistent running accuracy and smooth operation.
- Long-Term Reliability: The -2Z shields and factory-applied grease create a sealed-for-life system, minimizing maintenance needs and extending service life.
W 619/9-2Z Bearing Typical Application Areas
- Precision Instruments: Optical encoders, medical devices, and small measuring instruments.
- Small Electric Motors: High-speed spindles in dental handpieces, miniature fans, and small pumps.
- Office Automation Equipment: Printers, scanners, and copiers.
- Food and Beverage Machinery: Equipment requiring corrosion-resistant components for washdown.
- Robotics and Automation: Joints and guides in small, high-precision robotic arms.
