W 619/6-2Z Bearing Product Overview & Core Advantages
The W 619/6-2Z is a metric single row deep groove ball bearing designed for high precision applications requiring reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to efficiently handle radial loads, making it ideal for compact assemblies where space is limited and operational reliability is critical. The inclusion of shielded seals (2Z) and pre-applied grease lubrication ensures long service life with minimal maintenance.
W 619/6-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W 619/6 | Denotes the bearing series and size. A single row deep groove ball bearing with a 6 mm bore diameter. |
| 2Z | Signifies non-contact shields on both sides. This provides effective protection against contamination while allowing for high-speed operation with low friction. |
W 619/6-2Z Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from stainless steel for the rings, balls, and cage, providing superior corrosion resistance and durability in harsh environments.
- Optimized Load Capacity: The deep groove raceway is engineered to support significant radial dynamic load ratings (171 lbf), ensuring stable operation under load.
- High-Speed Capability: The non-contact shields and optimized internal geometry contribute to a high limiting speed of 50,000 rpm.
- Maintenance-Free Operation: The combination of shielded seals and factory-applied grease offers long-term, maintenance-free performance within a wide temperature range of -30°C to 120°C.
- Precision Fit: Manufactured to P0 tolerance class and standard CN radial internal clearance, guaranteeing consistent performance and ease of installation.
W 619/6-2Z Bearing Typical Application Areas
This bearing is ideally suited for applications requiring compact size, corrosion resistance, and high-speed operation. Typical uses include:
- Small electric motors and spindles
- Precision instruments and medical devices
- Office machinery and computer cooling fans
- Food processing equipment
- Other machinery where radial load support and low maintenance are key requirements.
