W 6202-Z/W64L Bearing Product Overview & Core Advantages
The W 6202-Z/W64L is a single row deep groove ball bearing engineered for precision and reliability in demanding applications. Constructed entirely from stainless steel components, it offers excellent corrosion resistance. Its core advantages include the ability to handle significant radial loads and moderate axial loads in both directions. The integrated Solid Oil lubrication and shielded design ensure long-term, maintenance-free operation, making it an ideal choice for applications requiring high reliability and cleanliness.
W 6202-Z/W64L Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W 6202 | Standard deep groove ball bearing series with 15mm bore, 35mm OD. |
| -Z | Denotes a shielded (non-contact) seal on one side, protecting against contaminants. |
| /W64L | Indicates the bearing is lubricated with Solid Oil, a polymer matrix saturated with oil, offering superior retention and contamination resistance compared to traditional greases. |
W 6202-Z/W64L Bearing Structural Features & Performance Benefits
- Corrosion Resistance & Cleanliness: Manufactured from stainless steel for the rings and balls, this bearing is ideal for environments exposed to moisture, chemicals, or where cleanliness is paramount.
- Maintenance-Free Operation: The combination of a shielded design and Solid Oil lubrication creates a sealed-for-life unit. This eliminates relubrication needs and prevents lubricant washout, ensuring consistent performance.
- High-Speed Capability: With a limiting speed of 30,000 rpm, the bearing is suitable for high-speed applications. The precision ABEC 1 tolerance and optimized internal geometry contribute to smooth, low-vibration operation at high rotational speeds.
- Robust Load Capacity: The deep groove raceway and high-quality construction provide a dynamic load rating of 1432 lbf and a static load rating of 809 lbf, enabling it to handle substantial radial loads effectively.
W 6202-Z/W64L Bearing Typical Application Areas
The W 6202-Z/W64L is widely used in industries and equipment where corrosion resistance, high speed, and low maintenance are critical. Key applications include:
- Food and Beverage Processing Machinery (conveyors, mixers)
- Medical and Laboratory Equipment (centrifuges, small motors)
- Chemical Handling Pumps and Mixers
- Precision Instruments and Optical Devices
- Electric Motors and Small Gearboxes in harsh environments
