W 6004-2Z Bearing Product Overview & Core Advantages
The W 6004-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Constructed entirely from stainless steel, it offers superior corrosion resistance. Its key advantage lies in its ability to handle significant radial loads while maintaining smooth operation. The inclusion of integrated shields (2Z) and pre-applied grease lubrication ensures long service life and makes it a maintenance-free solution, ideal for applications requiring high reliability and cleanliness.
Model Code In-Depth Analysis
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| W | Stainless Steel Bearing | Provides excellent corrosion resistance. |
| 6004 | Standard Metric Dimension Series (20mm Bore, 42mm OD, 12mm Width) | Ensures interchangeability and easy sourcing. |
| 2Z | Non-Contact Shields on Both Sides | Protects against contamination while minimizing friction, contributing to the high limiting speed. |
W 6004-2Z Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and optimized geometry enable high radial load capacity (1812 lbf dynamic, 1124 lbf static) and stable operation.
- All-Stainless-Steel Construction: Rings, balls, and cage are made from stainless steel, ensuring consistent performance and durability in harsh or washdown environments.
- Optimized for Speed: The low-friction design, combined with non-contact shields and effective grease lubrication, allows for a limiting speed of 19,000 rpm.
- Sealed and Lubricated for Life: The 2Z shields effectively retain grease and exclude contaminants, making the bearing a maintenance-free component for the majority of its service life.
- Standardized Tolerances: Manufactured to P0 tolerance class and standard CN radial internal clearance, ensuring predictable performance and ease of integration.
W 6004-2Z Bearing Typical Application Areas
This bearing is ideally suited for a wide range of applications where corrosion resistance, reliability, and low maintenance are critical. Key sectors include:
- Food and Beverage Processing Equipment (conveyors, mixers)
- Medical and Laboratory Devices
- Chemical Handling Equipment
- Electrical Motors and Small Gearboxes
